Philippine Legal Context

I. Introduction

In the Philippines, a deed of sale is often signed not personally by the owner or seller, but by another person acting as the seller’s representative. This commonly happens when the seller is abroad, elderly, ill, unavailable, or unable to personally appear before the buyer, notary public, Register of Deeds, bank, broker, developer, or government office.

The usual document used for this purpose is a Special Power of Attorney, commonly called an SPA.

A deed of sale signed through an SPA can be valid and legally effective, provided that the agent was properly authorized, the SPA is sufficient, the deed of sale follows legal requirements, and the transaction does not violate law, public policy, or the rights of third persons.

This topic is especially important in real estate transactions because mistakes in the SPA can delay or prevent registration of the sale, cause disputes among heirs or co-owners, expose the buyer to title problems, or even result in allegations of falsification, fraud, or simulated sale.

II. Basic Concept: What Is a Special Power of Attorney?

A Special Power of Attorney is a written authority given by one person, called the principal, to another person, called the agent or attorney-in-fact, authorizing the agent to perform specific acts on behalf of the principal.

In a sale transaction:

the principal is usually the owner or seller;
the agent is the person authorized to sign and complete the sale;
the buyer is the purchaser;
the deed of sale is the contract transferring ownership;
the SPA is the authority of the agent to sign for the seller.

The agent does not sell the property as owner. The agent sells it in a representative capacity.

III. Why an SPA Is Needed for a Deed of Sale

Under Philippine agency law, certain acts require special authority. A sale of real property or other substantial property is not an ordinary administrative act. It is an act of ownership.

The Civil Code generally requires a special power of attorney for important acts such as:

selling real property;
mortgaging property;
leasing real property for more than one year;
entering into compromise agreements;
waiving rights;
accepting or repudiating inheritance;
making payments that are not acts of administration;
any act of strict ownership.

Because a deed of sale transfers ownership, the authority to sell must be clear.

A general phrase such as “to manage my property” is usually not enough to authorize a sale. The SPA should specifically authorize the agent to sell, execute the deed of sale, receive payment, and perform acts necessary for transfer and registration, if those acts are intended.

IV. Deed of Sale vs. Special Power of Attorney

The two documents serve different purposes.

1. Deed of Sale

The deed of sale is the contract between seller and buyer. It contains the terms of the sale, including:

identity of seller;
identity of buyer;
description of the property;
purchase price;
payment terms;
warranties;
delivery of possession;
transfer of title;
taxes and expenses;
signatures;
notarization.

2. Special Power of Attorney

The SPA is not the sale itself. It is merely the principal’s authority for the agent to act.

It should identify:

the principal;
the agent;
the property;
the specific authority to sell;
the authority to sign documents;
the authority to receive payment, if applicable;
the date and place of execution;
notarization or consular acknowledgment, as needed.

A valid SPA does not by itself transfer ownership. Ownership is transferred through the sale and delivery, subject to registration rules for real property.

V. Is a Deed of Sale Signed Through SPA Valid?

Yes. A deed of sale signed by a duly authorized attorney-in-fact may be valid and binding on the principal.

The signature may appear in forms such as:

Juan Dela Cruz represented by Maria Dela Cruz as Attorney-in-Fact under Special Power of Attorney dated __________

or:

For and in behalf of Juan Dela Cruz: Maria Dela Cruz Attorney-in-Fact

The key is that the deed should make clear that the agent signs for the principal, not in the agent’s own personal capacity.

VI. Essential Requirements for Validity

A deed of sale signed through an SPA generally requires the following:

the principal has legal capacity to sell;
the principal owns or has the right to sell the property;
the SPA is valid and sufficiently specific;
the agent acts within the authority granted;
the deed of sale contains the essential elements of a valid sale;
the buyer has capacity to buy;
the object and price are certain or determinable;
consent is freely given;
the deed is properly notarized if it is intended to be a public document;
for real property, registration requirements are complied with.

VII. Essential Elements of Sale

A sale requires:

Consent of the contracting parties;
Object certain, such as land, condominium unit, house, vehicle, shares, or personal property;
Price certain in money or its equivalent.

When the seller acts through an agent, the seller’s consent is manifested through the agent, but only if the agent has proper authority.

If the agent has no authority, the seller may not be bound unless the seller later ratifies the transaction.

VIII. Real Property Sales Through SPA

Most SPA-related issues arise in real estate transactions.

A deed of sale involving land, condominium units, or houses is usually executed as a notarized document so that it may be used for:

payment of capital gains tax;
payment of documentary stamp tax;
securing a certificate authorizing registration;
transfer tax payment;
registration with the Register of Deeds;
issuance of a new title;
updating tax declarations.

The Register of Deeds, Bureau of Internal Revenue, local assessor, banks, and buyers often examine the SPA carefully.

If the SPA is defective, the sale may still be disputed or may not be accepted for registration.

IX. SPA Must Specifically Authorize the Sale

The SPA should not be vague. It should clearly state that the agent is authorized to sell the specific property.

A strong SPA usually includes authority:

to sell the property;
to negotiate and agree on price and terms;
to sign the deed of absolute sale or conditional sale;
to receive payment;
to issue receipts;
to deliver possession;
to sign tax forms;
to pay taxes and fees;
to process BIR requirements;
to receive the certificate authorizing registration;
to sign transfer documents;
to register the sale with the Register of Deeds;
to secure the new title or tax declaration;
to represent the principal before government offices.

If the SPA only says “to administer,” “to manage,” or “to take care of my property,” that may be insufficient for a sale.

X. Description of the Property in the SPA

The SPA should accurately identify the property. For real property, it should preferably include:

title number;
lot number;
block number;
survey number;
condominium certificate of title number, if applicable;
tax declaration number;
exact location;
area;
registered owner;
technical description, when available.

If the SPA authorizes sale of “my property in Quezon City” but the principal owns several properties in Quezon City, the authority may be questioned.

A precise property description prevents disputes and registration issues.

XI. Authority to Sell vs. Authority to Receive Payment

Authority to sell does not always automatically mean authority to receive payment, especially where the principal wants payment to be made directly to him or her.

For buyer protection, the SPA should state whether the attorney-in-fact may:

receive the full purchase price;
receive earnest money or down payment;
receive installment payments;
issue receipts;
deposit checks;
sign acknowledgment of payment;
turn over possession upon payment.

If the SPA is silent, the buyer should be cautious about paying the agent. The safest arrangement is to pay directly to the principal’s bank account or require clear written authority for the agent to receive payment.

XII. Authority to Negotiate Price and Terms

The SPA may set a fixed selling price or allow the agent to negotiate.

Examples:

To sell the property for a price not lower than ₱5,000,000.00.

or:

To sell the property at such price and under such terms and conditions as my attorney-in-fact may deem just and reasonable.

If the SPA sets a minimum price and the agent sells below that amount, the agent may have exceeded authority. This can create disputes between the principal, agent, and buyer.

XIII. Authority to Sign the Deed of Sale

The SPA should specifically authorize the agent to sign the deed.

A clause may state:

To sign, execute, and deliver the Deed of Absolute Sale, Deed of Conditional Sale, Contract to Sell, and all other documents necessary to transfer the property to the buyer.

This is important because some SPAs authorize negotiation but not execution of the final deed.

XIV. Notarization of the SPA

For real estate transactions, the SPA should be notarized. A notarized SPA becomes a public document and is generally required by the Register of Deeds, BIR, banks, and government offices.

A private, unnotarized SPA may be problematic for registration and may be easier to challenge.

The notary public should verify the identity and personal appearance of the principal. A notarized SPA where the principal did not personally appear before the notary may be attacked as defective or falsified.

XV. SPA Executed Abroad

If the principal is outside the Philippines, the SPA must usually be executed abroad and properly authenticated for use in the Philippines.

Depending on the country, this may be done through:

Apostille, if the country is a party to the Apostille Convention; or
Consular acknowledgment or authentication, if apostille is not applicable.

A Philippine embassy or consulate may also acknowledge an SPA executed abroad.

For Philippine use, the SPA should be in a form acceptable to Philippine institutions, especially the Register of Deeds and BIR.

If the SPA is in a foreign language, a certified English translation may be required.

XVI. Apostilled SPA

An apostille is a certificate that authenticates the origin of a public document for use in another country that is also a party to the Apostille Convention.

An apostilled SPA executed abroad may be accepted in the Philippines if properly issued by the competent authority of the foreign country.

However, practical requirements may vary. Some government offices, banks, developers, or registries may still examine whether the SPA clearly authorizes the transaction.

The apostille authenticates the document’s public character; it does not cure a vague or insufficient authority.

XVII. Consularized SPA

Before apostille practice became common, Filipinos abroad often executed SPAs before a Philippine consular officer. The consular officer acknowledged the document, making it usable in the Philippines.

Consularized SPAs remain common, especially in countries or situations where apostille is not used.

A consularized SPA should still contain complete and specific authority.

XVIII. SPA for Sale of Conjugal or Community Property

A critical issue arises when the property is conjugal or part of the absolute community of property between spouses.

If a married person sells property that belongs to the conjugal partnership or absolute community, the consent of the other spouse may be required.

Depending on the property regime and the facts, a deed of sale signed by only one spouse or by an agent of only one spouse may be void, voidable, or otherwise challengeable.

Best practice:

both spouses should sign the deed of sale; or
both spouses should execute the SPA; or
the non-signing spouse should give clear written consent or authority.

If the title is in the name of “Juan Dela Cruz, married to Maria Dela Cruz,” the buyer should not assume Juan alone may sell. The phrase “married to” does not always mean the spouse is a co-owner, but it is a warning sign requiring due diligence.

XIX. Sale of Exclusive Property of a Married Person

If the property is exclusive or separate property of one spouse, that spouse may generally sell it. However, depending on the property regime and use of the property as family home, spousal consent may still become relevant.

A buyer should check:

date of marriage;
date and mode of acquisition;
title annotations;
marriage settlement, if any;
whether the property is the family home;
whether improvements were made using community or conjugal funds.

If the owner is abroad and authorizes an agent, the SPA should still be executed by the true owner. If spousal consent is needed, the spouse should also sign or issue authority.

XX. Sale of Co-Owned Property Through SPA

If property is co-owned, one co-owner cannot sell the entire property without authority from the other co-owners.

A co-owner may generally sell only his or her undivided share, unless authorized to sell the whole property.

If a deed of sale is signed by an attorney-in-fact, the buyer must confirm that:

each co-owner signed the deed; or
each co-owner executed an SPA; or
the agent is authorized by all co-owners.

For inherited property, all heirs must generally participate unless an estate proceeding, extrajudicial settlement, or valid authority gives someone power to sell.

XXI. Sale of Inherited Property Through SPA

Inherited property is a common source of SPA-related disputes.

If the registered owner is deceased, an heir cannot simply sign a deed of sale using an SPA from the deceased. Agency is generally extinguished by death. A dead person cannot be represented by an attorney-in-fact.

The proper process usually involves:

settlement of estate;
extrajudicial settlement among heirs, if allowed;
payment of estate tax;
transfer to heirs or simultaneous sale by heirs;
signatures or SPAs from all necessary heirs.

If one heir signs for others, each represented heir must have given a valid SPA.

XXII. Death of the Principal

As a general rule, agency is extinguished by the death of the principal.

This means that if the seller executed an SPA but died before the deed of sale was signed, the agent’s authority usually ended upon death. A deed of sale signed after the principal’s death may be invalid or highly questionable.

The buyer should verify that the principal is alive at the time the agent signs the deed of sale.

If the principal died after signing the deed but before registration, different issues may arise. The sale may still be valid if perfected and executed during the principal’s lifetime, but tax, estate, and registration issues may need careful handling.

XXIII. Revocation of SPA

The principal may generally revoke the SPA, unless the agency is coupled with an interest or falls under special rules.

A buyer should check whether the SPA remains effective at the time of sale.

Risk indicators include:

old SPA;
family dispute;
principal abroad and unreachable;
agent rushing the sale;
sale below market value;
buyer cannot speak with principal;
conflicting agents;
notice of revocation;
annotated adverse claim;
pending litigation.

If the principal revoked the SPA before the sale and the buyer had notice, the sale may not bind the principal.

XXIV. Expiration of SPA

Some SPAs contain an expiration date or are limited to a particular transaction.

Example:

This authority shall be valid until 31 December 2026.

If the agent signs the deed after expiration, the authority may be invalid.

If there is no expiration date, the SPA may remain effective until revoked, fulfilled, or extinguished by law. Still, institutions may question very old SPAs, especially for high-value real estate transactions.

XXV. Substitution or Delegation by Attorney-in-Fact

An agent cannot always delegate authority to another person. If the principal wants the attorney-in-fact to appoint a substitute or sub-agent, the SPA should expressly allow substitution.

Without authority to substitute, a deed signed by a substitute may be challenged.

A clause may state:

To appoint a substitute or sub-attorney-in-fact under the same terms and conditions, with full power of substitution and revocation.

Even with such clause, buyers should carefully verify the chain of authority.

XXVI. Ratification of Unauthorized Sale

If an agent signs a deed of sale without sufficient authority, the principal may later ratify the act.

Ratification may be express or implied. Express ratification is safer and may be done through:

a confirmatory deed;
affidavit of ratification;
new deed signed by principal;
board resolution, if corporation;
acceptance of payment with knowledge of the sale.

Ratification generally means the principal adopts the agent’s act as his or her own.

However, a buyer should not rely on possible future ratification. The safer course is to require valid authority before payment and signing.

XXVII. Unauthorized Sale and Its Effects

If the attorney-in-fact had no authority to sell, exceeded authority, or used a forged SPA, possible consequences include:

the sale may not bind the principal;
title transfer may be denied or later cancelled;
the buyer may sue the agent for damages;
the principal may recover the property;
criminal complaints may arise;
notarial violations may be investigated;
banks may refuse financing;
the Register of Deeds may deny registration;
the buyer may lose money if payment was made to the wrong person.

Good faith is important, but it may not always protect a buyer when the agent had no authority and the principal did not participate.

XXVIII. Forged SPA

A forged SPA conveys no authority. If the principal’s signature is forged, the attorney-in-fact has no valid authority to sell.

Warning signs include:

principal denies signing;
principal was abroad but SPA was notarized in the Philippines;
notarial details are suspicious;
ID details are inconsistent;
signature does not match known records;
document lacks notarial register details;
notary is not commissioned;
witnesses are unknown;
agent refuses direct verification with principal;
sale price is unusually low.

A buyer should verify the SPA before paying.

XXIX. Buyer’s Due Diligence

A buyer dealing with an attorney-in-fact should not rely only on the agent’s representations. Due diligence is essential.

The buyer should check:

original owner’s duplicate title;
certified true copy of title from the Register of Deeds;
tax declaration;
real property tax clearance;
identity of principal;
identity of attorney-in-fact;
original notarized, apostilled, or consularized SPA;
notarial details;
principal’s marital status;
spousal consent;
co-owner consent;
encumbrances, liens, mortgages, adverse claims, notices of lis pendens;
estate or inheritance issues;
possession and occupancy;
subdivision or condominium restrictions;
homeowners’ association or condominium dues;
BIR and local tax obligations.

The buyer should also try to communicate directly with the principal, especially if the principal is abroad.

XXX. Payment Precautions

Payment is one of the riskiest parts of an SPA sale.

Best practices include:

pay directly to the principal’s bank account;
use manager’s check payable to the principal;
avoid cash payments to the agent unless expressly authorized;
require written acknowledgment from the principal;
require receipt signed in representative capacity;
verify bank account ownership;
use escrow if possible;
withhold final payment until taxes, CAR, and registration documents are complete;
clearly state in the deed who receives payment and how.

If the SPA authorizes the agent to receive payment, the deed should mention that payment to the agent is payment to the principal.

XXXI. Proper Signature Format in the Deed of Sale

The deed should clearly show representation.

Example:

Seller: JUAN DELA CRUZ represented by MARIA DELA CRUZ Attorney-in-Fact under SPA dated __________

Signature block:

For and in behalf of JUAN DELA CRUZ:

MARIA DELA CRUZ Attorney-in-Fact

Avoid having the agent sign simply as “seller” without indicating representative capacity. That can create ambiguity.

XXXII. Notarization of the Deed of Sale

The deed of sale should be notarized if it will be used to transfer title or presented to government agencies.

The notary should require the personal appearance of:

the buyer;
the attorney-in-fact signing for the seller;
other parties who sign the deed.

The principal need not appear before the notary for the deed if the principal validly appointed the attorney-in-fact. However, the SPA itself must be properly acknowledged by the principal.

The SPA is often attached to or referenced in the deed.

XXXIII. Should the SPA Be Attached to the Deed?

For real property transactions, the SPA is usually attached to the deed of sale when submitted to the BIR and Register of Deeds.

The deed should refer to the SPA by:

date;
notary public or apostille/consular details;
document number, page number, book number, series, if notarized;
place of execution.

Attaching the SPA helps establish authority for the signing.

XXXIV. Registration With the Register of Deeds

For land or condominium sales, the buyer normally registers the deed of sale with the Register of Deeds after paying required taxes.

The Register of Deeds may require:

notarized deed of sale;
owner’s duplicate certificate of title;
valid SPA;
tax clearance;
certificate authorizing registration from the BIR;
transfer tax receipt;
real property tax clearance;
IDs;
other supporting documents.

If the SPA is defective, unclear, expired, unauthenticated, or insufficient, registration may be refused or suspended.

XXXV. BIR Requirements

For real estate sales, the BIR generally requires documents for tax processing, including:

notarized deed of sale;
title;
tax declaration;
tax identification numbers;
valid IDs;
proof of payment of taxes;
SPA if a party signs through representative;
proof of authority if corporate or estate-related;
other documents depending on the transaction.

Taxes may include capital gains tax, creditable withholding tax, documentary stamp tax, value-added tax in certain cases, donor’s tax implications if price is too low, and other applicable taxes.

The BIR may examine whether the SPA authorizes the agent to sign and process tax documents.

XXXVI. Local Government Requirements

The local government may require:

transfer tax payment;
tax clearance;
updated real property tax records;
new tax declaration;
IDs;
SPA for representatives processing documents.

The attorney-in-fact may need authority not only to sell but also to process local transfer requirements.

XXXVII. Sale of Motor Vehicle Through SPA

A deed of sale for a motor vehicle may also be signed through SPA.

The SPA should identify the vehicle by:

make;
model;
year;
plate number;
engine number;
chassis number;
certificate of registration number.

The agent should be authorized to sign the deed of sale, receive payment, deliver the vehicle, process transfer with the Land Transportation Office, and sign related documents.

Buyers should check the certificate of registration, official receipt, encumbrance status, chassis and engine numbers, and whether the vehicle is subject to mortgage or alarm.

XXXVIII. Sale of Shares of Stock Through SPA

Shares of stock may be sold through an attorney-in-fact if properly authorized.

The SPA should identify:

corporation;
certificate numbers;
number of shares;
class of shares;
authority to sign deed of sale or stock transfer;
authority to endorse stock certificates;
authority to receive payment;
authority to update corporate stock and transfer book.

Corporate rules, restrictions on transfer, right of first refusal, and tax requirements should be checked.

XXXIX. Corporate Seller Acting Through Representative

If the seller is a corporation, the document is usually not called an SPA from a natural person but a board resolution, secretary’s certificate, or corporate authorization.

A corporate officer must have authority from the board to sell corporate property, especially real estate.

The buyer should ask for:

board resolution approving the sale;
secretary’s certificate;
articles of incorporation;
latest general information sheet;
IDs of authorized signatories;
corporate tax documents;
proof that the corporation owns the property.

If a corporate officer signs a deed of sale without authority, the sale may be challenged.

XL. Partnership, Association, or Estate Representative

For partnerships, associations, estates, or trusts, authority must be verified according to the governing documents and law.

Possible authority documents include:

partnership resolution;
managing partner authority;
board or trustee resolution;
court appointment;
letters of administration;
special administrator authority;
extrajudicial settlement;
SPA from heirs;
trust instrument.

The label “attorney-in-fact” is not enough. The source and scope of authority must be clear.

XLI. SPA and Brokers

A real estate broker’s authority to market property is not the same as authority to sell and sign a deed of sale.

A broker may be authorized to find a buyer, negotiate, advertise, or receive reservation payments, but not necessarily to sign the deed of sale or receive full payment.

If the broker signs for the owner, a separate SPA or written authority must clearly authorize it.

Buyers should distinguish among:

authority to sell as broker;
authority to negotiate;
authority to accept offers;
authority to receive reservation fee;
authority to sign the deed of sale;
authority to receive the purchase price.

XLII. SPA and Contract to Sell

A contract to sell may also be signed through an SPA.

A contract to sell is different from a deed of absolute sale. In a contract to sell, ownership usually remains with the seller until full payment and fulfillment of conditions.

If the attorney-in-fact is authorized only to sign a contract to sell but not a deed of absolute sale, a separate or broader SPA may be needed later for the final deed.

XLIII. SPA and Deed of Conditional Sale

A deed of conditional sale may involve conditions before ownership transfers. The SPA should authorize the agent to agree to those conditions.

If the terms include installment payments, forfeiture clauses, possession turnover, penalties, or mortgage obligations, the principal should authorize the agent clearly.

XLIV. SPA and Donation Disguised as Sale

Sometimes a sale is made for a price far below market value, or no real payment is made. This may raise issues of simulated sale, donation, tax exposure, or fraud against heirs or creditors.

An SPA to sell does not necessarily authorize the agent to donate. If the transaction is actually a donation, the formalities for donation must be followed.

A buyer should ensure that the sale has real consideration and that payment can be proven.

XLV. SPA and Simulated Sale

A deed of sale may be simulated if the parties did not intend a real sale, or if the stated price was not truly paid.

If an agent signs a simulated deed, disputes may arise among family members, heirs, creditors, or the principal.

Evidence of simulation may include:

no payment records;
buyer never took possession;
seller continued to act as owner;
price grossly inadequate;
deed executed to avoid creditors;
transaction done shortly before death;
attorney-in-fact benefited personally;
buyer is closely related to agent;
principal was incapacitated.

A notarized deed is strong evidence of its contents, but it can be challenged with sufficient proof.

XLVI. SPA and Principal’s Capacity

The principal must have legal capacity when executing the SPA.

If the principal was mentally incapacitated, unconscious, under undue influence, or unable to understand the document, the SPA may be attacked.

Common issues include elderly sellers, sick principals, or principals abroad who allegedly signed documents under pressure.

Evidence may include medical records, witness testimony, video calls, notarial records, and surrounding circumstances.

XLVII. SPA and Fraud by Attorney-in-Fact

An attorney-in-fact owes duties to the principal. The agent must act within authority and in the principal’s interest.

Fraud by the agent may include:

selling below authorized price;
keeping the proceeds;
falsifying payment acknowledgment;
selling to himself or a relative without authority;
hiding the transaction from the principal;
using a forged SPA;
changing pages of the SPA;
misrepresenting the terms to the buyer;
double-selling the property.

The principal may sue the agent for damages, accounting, reconveyance, or other remedies. Criminal liability may also arise depending on the facts.

XLVIII. Can the Attorney-in-Fact Sell the Property to Himself?

An agent generally should not purchase the property entrusted to him for sale without the principal’s informed consent. This is because of conflict of interest and fiduciary duty.

If the principal wants to allow the attorney-in-fact to buy the property, the SPA should expressly authorize self-dealing or sale to the agent, and the transaction should be fair and well documented.

Otherwise, the sale may be challenged.

XLIX. Double Sale Issues

A principal may sell the property personally while an agent also sells it under SPA, or two agents may sell to different buyers.

Double sale disputes are governed by rules on priority, good faith, possession, and registration.

A buyer should register the sale promptly and verify the title before payment. If there is any adverse claim, pending sale, or possession by another buyer, the transaction becomes risky.

L. SPA and Adverse Claims

If someone disputes the agent’s authority or claims ownership, an adverse claim or notice of lis pendens may appear on the title.

A buyer should not ignore title annotations.

Common annotations include:

mortgage;
adverse claim;
notice of lis pendens;
levy;
attachment;
encumbrance;
restrictions;
right of way;
homeowners’ restrictions;
court orders.

The SPA does not override these annotations.

LI. Effect of Notarization of the Deed and SPA

A notarized document is generally considered a public document and is entitled to evidentiary weight. It is admissible in evidence without further proof of authenticity, subject to legal objections.

However, notarization does not make an invalid transaction valid if essential elements are missing. It does not cure:

forgery;
lack of authority;
incapacity;
fraud;
absence of consent;
illegal object;
lack of spousal consent where required;
sale by a non-owner;
expired or revoked SPA.

Notarization strengthens form, not substance.

LII. Common Defects in SPA-Based Sales

Common problems include:

SPA does not mention authority to sell.
SPA does not identify the property clearly.
SPA is not notarized, apostilled, or consularized.
SPA is expired.
SPA was revoked.
Principal died before sale.
Principal’s signature was forged.
Agent exceeded price limits.
Agent received payment without authority.
Only one spouse executed SPA for conjugal property.
Only one co-owner authorized sale of entire property.
SPA authorizes mortgage but not sale.
SPA authorizes sale to a specific buyer only, but agent sold to another.
SPA authorizes sale of one property, but deed covers another.
SPA is a photocopy and original cannot be produced.
SPA was notarized without personal appearance.
SPA lacks competent evidence of identity.
Agent signs personally instead of as representative.
Deed does not refer to the SPA.
The sale violates restrictions on the title.

LIII. Remedies if the Sale Is Questioned

Depending on the facts, possible remedies include:

action for annulment of deed;
action for declaration of nullity;
reconveyance;
cancellation of title;
quieting of title;
damages;
accounting against the agent;
criminal complaint for falsification, estafa, or other offenses;
administrative complaint against notary public;
adverse claim annotation;
injunction;
specific performance;
ratification or confirmatory deed.

The correct remedy depends on whether the defect involves lack of authority, forgery, fraud, breach of agency, lack of consent, or registration issues.

LIV. Buyer in Good Faith

A buyer in good faith is one who buys property without notice of any defect and after reasonable inquiry.

However, when a seller acts through an attorney-in-fact, the buyer is generally expected to examine the agent’s authority. The SPA itself is a warning that the buyer is not dealing directly with the owner.

A buyer may not be considered in good faith if he or she ignored obvious red flags, such as:

vague SPA;
suspicious notarization;
sale price far below market value;
refusal to communicate with principal;
property occupied by someone else;
title annotations;
conflicting documents;
missing owner’s duplicate title;
agent’s name does not match documents;
principal allegedly abroad but SPA notarized locally;
marital or co-ownership issues.

Good faith requires diligence.

LV. Drafting Tips for a Strong SPA

A well-drafted SPA for sale of real property should include:

full name, citizenship, civil status, address, and ID details of principal;
full name, citizenship, civil status, address, and ID details of attorney-in-fact;
clear property description;
express authority to sell;
authority to determine or accept price and terms;
authority to sign deed of sale, contract to sell, and related documents;
authority to receive payment, if intended;
authority to issue receipts and acknowledgments;
authority to deliver possession;
authority to process BIR, local government, Register of Deeds, assessor, and other offices;
authority to pay taxes and fees;
authority to receive CAR and new title, if needed;
authority to sign forms, affidavits, and undertakings;
duration of authority;
power of substitution, if intended;
principal’s signature;
spouse’s signature or consent, if needed;
witnesses;
notarization, apostille, or consular acknowledgment.

LVI. Sample SPA Clause for Sale of Real Property

A typical authority clause may read:

To sell, transfer, and convey, under such price and terms as my attorney-in-fact may deem proper, my parcel of land covered by Transfer Certificate of Title No. ______, located at ______, including all improvements thereon; to negotiate with buyers; to sign and execute the Deed of Absolute Sale, Contract to Sell, Deed of Conditional Sale, and all other documents necessary for the transaction; to receive the purchase price and issue receipts; to pay taxes and fees; to sign BIR, local government, Register of Deeds, assessor’s office, and other forms; and to do all acts necessary to complete the sale and transfer of title.

This is only a sample. The actual wording should be adapted to the transaction.

LVII. Drafting Tips for the Deed of Sale

A deed of sale signed through SPA should:

identify the principal as seller;
identify the attorney-in-fact and the SPA;
attach or reference the SPA;
state that the attorney-in-fact signs for and on behalf of the seller;
describe the property accurately;
state the purchase price and payment method;
identify who received payment;
include warranties;
state delivery of possession;
allocate taxes and expenses;
provide for cooperation in transfer;
include proper signature blocks;
be notarized;
include valid IDs and competent evidence of identity.

LVIII. Sample Signature Block

For the seller:

JUAN DELA CRUZ Seller By: MARIA DELA CRUZ Attorney-in-Fact Under SPA dated __________

Or:

For and in behalf of JUAN DELA CRUZ:

MARIA DELA CRUZ Attorney-in-Fact

For the buyer:

PEDRO SANTOS Buyer

The acknowledgment portion should also reflect that the attorney-in-fact personally appeared and exhibited the SPA and identification documents.

LIX. Frequently Asked Questions

Can someone sell my property using an SPA?

Yes, if you validly authorized that person to sell the property and the person acts within the authority granted.

Is a handwritten SPA valid?

It may be valid between parties if it contains the required authority and signature, but for real estate registration, notarization or proper authentication is usually required.

Does an SPA need to be notarized?

For real property transactions and government registration, yes, it should be notarized, apostilled, or consularized depending on where it is executed.

Can an SPA be used if the owner is abroad?

Yes, but it should be properly executed abroad and authenticated or apostilled for use in the Philippines.

Can the attorney-in-fact receive payment?

Only if the SPA authorizes it, or if circumstances and law support such authority. For safety, the SPA should expressly state this power.

Can the attorney-in-fact sign the deed of sale?

Yes, if the SPA specifically authorizes the agent to sign the deed or sell the property.

Can a general power of attorney authorize sale?

A general power of attorney may not be enough. Sale of real property generally requires special authority.

What if the SPA is fake?

A forged SPA gives no authority. The sale may be challenged, and criminal liability may arise.

What if the principal dies before the sale?

The agency generally ends upon the principal’s death. A sale signed by the agent after the principal’s death is usually invalid or highly questionable.

What if the principal revokes the SPA?

If revoked before the sale, the agent can no longer validly sell, especially if the buyer had notice of revocation.

Can an attorney-in-fact sell to himself?

Generally, this is not allowed unless clearly authorized by the principal and done with full disclosure and fairness.

Is the buyer safe if the deed is notarized?

Not always. Notarization helps, but it does not cure lack of authority, forgery, incapacity, or other serious defects.

LX. Practical Checklist for Buyers

Before buying property from an attorney-in-fact, ask for and verify:

original notarized, apostilled, or consularized SPA;
valid IDs of principal and attorney-in-fact;
certified true copy of title;
owner’s duplicate title;
tax declaration;
real property tax clearance;
marital status of seller;
spouse’s consent or SPA, if needed;
co-owner or heir authority, if applicable;
proof principal is alive and has not revoked SPA;
direct confirmation from principal;
authority to receive payment;
payment trail to principal;
title annotations;
possession and occupancy status;
broker authority, if broker involved;
BIR and transfer requirements.

LXI. Practical Checklist for Principals

Before giving an SPA, the principal should:

choose a trustworthy attorney-in-fact;
specify the property;
set price limits if desired;
specify whether the agent may receive payment;
require accounting;
limit duration;
prohibit self-dealing unless intended;
require updates before signing final documents;
keep copies of the SPA;
inform the buyer how payment should be made;
revoke the SPA in writing if no longer needed;
notify relevant parties of revocation.

LXII. Practical Checklist for Attorneys-in-Fact

The attorney-in-fact should:

act only within the SPA;
disclose representative capacity;
avoid conflicts of interest;
keep records of negotiations;
issue receipts only if authorized;
remit proceeds promptly;
avoid changing terms beyond authority;
preserve documents;
account to the principal;
avoid signing after expiration, revocation, or death of principal;
avoid self-dealing without express authority.

LXIII. Practical Checklist for Notaries

A notary handling a deed signed through SPA should:

verify the identity of the appearing attorney-in-fact;
inspect the SPA;
ensure the deed identifies the principal and agent;
confirm the attorney-in-fact signs in representative capacity;
require competent evidence of identity;
record notarial details properly;
avoid notarizing if the parties do not personally appear;
ensure the acknowledgment reflects the correct capacity of the signer.

For the SPA itself, the principal must personally appear before the notary or proper acknowledging officer.

LXIV. Common Litigation Scenarios

Disputes often arise when:

siblings challenge sale by one heir using alleged SPA;
spouse claims lack of consent;
principal denies signing SPA;
buyer paid agent but principal claims no payment;
agent sold below authorized price;
principal died before deed was signed;
SPA was old and allegedly revoked;
deed was signed after the property was already sold to another buyer;
agent sold property to himself or a relative;
property was conjugal but only one spouse authorized sale;
BIR or Register of Deeds refused documents;
buyer discovers title annotations after payment.

Many of these disputes could have been avoided by better drafting and due diligence.

LXV. Legal Effects After Valid Sale Through SPA

If the SPA and deed of sale are valid, the transaction generally binds the principal as if the principal personally signed.

For real property, the buyer may proceed with:

payment of taxes;
securing BIR certificate authorizing registration;
payment of local transfer tax;
registration with the Register of Deeds;
issuance of new certificate of title;
issuance of new tax declaration;
turnover of possession, if not already delivered.

The buyer becomes owner subject to the rules on sale, delivery, and registration.

LXVI. Distinction Between Validity and Registrability

A deed of sale may be valid between the parties but not immediately registrable if documentary requirements are incomplete.

For example, the parties may have a valid sale, but the Register of Deeds may require a clearer SPA, tax clearance, CAR, or other documents before transfer.

Conversely, registration does not always cure fundamental defects like forgery or lack of authority.

LXVII. Risk Allocation in the Deed

A deed of sale may include representations and warranties from the seller, through the attorney-in-fact, such as:

seller is the lawful owner;
property is free from liens except disclosed encumbrances;
SPA is valid, subsisting, and unrevoked;
principal is alive and has capacity;
taxes are paid or will be paid;
no pending case affects the property;
no other sale or contract exists;
attorney-in-fact has authority to sign and receive payment.

The deed may also include indemnity provisions if any representation is false.

LXVIII. When to Require the Principal’s Personal Signature Instead

Even if an SPA is available, it may be better to require the principal to sign personally when:

transaction value is high;
buyer cannot verify the principal;
SPA is old or vague;
there are family disputes;
property is inherited;
title has annotations;
principal is elderly or ill;
agent is also the buyer;
property is conjugal or co-owned;
buyer is paying a large amount directly to agent;
bank financing requires stricter documentation.

An SPA is convenient, but personal signing by the owner is often safer.

LXIX. Conclusion

A deed of sale signed through a Special Power of Attorney is valid in the Philippines when the attorney-in-fact is properly and specifically authorized, the principal has capacity and ownership rights, the deed contains the essential elements of sale, and legal formalities are observed.

The most important rule is that the SPA must clearly grant the power to sell. For real property, the SPA should be notarized, apostilled, or consularized as appropriate, should accurately identify the property, and should expressly authorize the agent to sign the deed of sale and perform transfer-related acts. If the agent will receive payment, that authority should also be clearly stated.

Buyers should exercise heightened due diligence because they are not dealing directly with the owner. They should verify the SPA, title, identity of the principal and agent, marital or co-ownership issues, authority to receive payment, and the absence of revocation, death, forgery, or title defects.

For sellers, the SPA should be carefully drafted to limit risk and prevent misuse. For attorneys-in-fact, the authority must be followed strictly, with transparency, accounting, and loyalty to the principal.

In Philippine practice, SPA-based sales are common and useful, especially for overseas Filipinos and unavailable owners. But they require careful documentation. A valid SPA can make a sale efficient; a defective SPA can make the transaction vulnerable to denial of registration, civil litigation, cancellation of title, or criminal accusations.
