Quick answer

Usually, one heir cannot sell the entire inherited property—or a specific physical portion of it—without the consent of the other heirs while the estate remains undivided.

An heir may generally sell only:

The heir’s undivided hereditary interest in the estate; or
The particular property or portion exclusively awarded to that heir after a valid partition.

A deed signed by only one heir does not ordinarily transfer the non-signing heirs’ shares. At most, the buyer acquires the selling heir’s undivided interest and steps into the seller’s position as a co-owner, subject to estate debts, settlement, partition, taxes, title defects, and any applicable right of legal redemption.

The exact result depends on what the deed describes, whether the estate has already been settled and partitioned, who the lawful heirs are, whether there is a will, whether the property belonged partly to a surviving spouse, and whether minors, creditors, tenants, or agrarian-reform restrictions are involved.

Why inherited property is usually owned in common

Successional rights pass from the moment of the owner’s death under Article 777 of the Civil Code. But when there are two or more heirs, Article 1078 provides that the decedent’s estate is owned by them in common before partition, subject to payment of the decedent’s debts.

This means that, before partition, each heir generally owns an ideal or proportional share in the estate, not an automatically identified bedroom, floor, frontage, or surveyed portion of a particular lot.

For example, an heir entitled to one-fourth of an undivided parcel does not necessarily own the northern one-fourth. The heir owns an undivided one-fourth interest throughout the property until a valid partition determines what specific property or portion will be assigned to that heir.

These rules appear in the Civil Code of the Philippines, particularly Articles 493, 777, 1078 and 1088.

What one heir may sell without the others’ consent

Article 493 of the Civil Code allows each co-owner to alienate, assign, or mortgage the co-owner’s share. The transaction’s effect, however, is limited to the portion ultimately allotted to that co-owner when the co-ownership ends.

Accordingly, an heir may generally sell an undivided hereditary right or ideal share without first obtaining every co-heir’s consent. The deed should accurately identify the subject as the seller’s hereditary rights or undivided interest—not the whole property and not an unpartitioned physical portion.

The Supreme Court has repeatedly applied this rule:

In Acabal v. Acabal, G.R. No. 148376, March 31, 2005, the Court explained that a co-owner may alienate an undivided share, with the transaction limited to the portion that may later be allotted to the seller.
In Spouses Del Campo v. Court of Appeals, G.R. No. 168156, December 6, 2006, the Court recognized that an heir may dispose of an ideal share even while the property is under administration, subject to the outcome of the estate proceedings.
In Cabrera v. Ysaac, G.R. No. 166790, November 19, 2014, the Court reiterated that a buyer of an heir’s undivided share becomes a co-owner only to the extent of the seller’s interest.

The buyer therefore does not automatically acquire exclusive possession of a chosen part of the land. The buyer assumes the risks and limitations attached to the seller’s unsettled share.

What one heir generally cannot sell alone

Without authority from the other owners, one heir generally cannot validly transfer:

The entire inherited property, including the shares of the other heirs;
A definite physical portion identified by boundaries, measurements, floor, room, or location when no valid partition has assigned that portion to the seller;
A larger fractional interest than the seller actually inherited;
A minor heir’s share without the required legal representation and court authority;
Property that belongs partly to the surviving spouse as the spouse’s own share in the former absolute community or conjugal partnership; or
Property controlled by an executor or administrator in a pending estate proceeding, except in accordance with the applicable court orders and Rules of Court.

In Heirs of Ureta v. Heirs of Ureta, G.R. No. 246096, January 27, 2021, the Supreme Court distinguished an undivided interest from a definite portion. Before partition, a co-owner may sell the undivided interest but cannot unilaterally select and sell a particular physical area without the other co-owners’ consent.

Is a sale of the entire property automatically void?

Not necessarily in its entirety.

When one co-owner purports to sell the whole property without the others’ authority, Philippine cases commonly treat the conveyance as effective only to the extent of the seller’s lawful share, when the contract can legally operate that way. It does not bind the other co-owners’ interests.

In Spouses Valdez v. Tabisula, G.R. No. 151334, February 13, 2013, the Supreme Court held that a sale of the entire property by one co-owner transferred only that seller’s share, making the buyers co-owners to that extent.

Similarly, Molina v. Court of Appeals, G.R. No. 232437, June 30, 2021 recognized that an unauthorized sale was not totally ineffective where the seller could validly transfer his own interest.

That principle does not validate forgery, a fictitious sale, lack of consent by the person whose share was supposedly sold, or a transaction otherwise void under law. Nor does it guarantee that the buyer will receive the particular area described in the deed. The result must be assessed from the deed, title, estate records, succession documents, and surrounding facts.

When consent of all heirs is ordinarily required

All heirs—or their properly authorized representatives—will generally need to participate when they intend to:

Sell the inherited property as one whole;
Execute an extrajudicial settlement that divides or disposes of the estate;
Assign a specific parcel or physical portion to one heir;
Combine an extrajudicial settlement and sale in one document;
Authorize one heir to sign for everyone through valid special powers of attorney; or
Transfer title from the decedent directly to a buyer through a settlement with sale.

Consent must be genuine and properly documented. Simply knowing about negotiations, receiving a family message, or remaining silent does not automatically authorize another heir to sell one’s share.

Selling after partition

Once a valid partition assigns a particular property or definite portion exclusively to an heir, Article 1091 of the Civil Code gives that heir exclusive ownership of the property adjudicated to him or her.

That heir may then sell the allotted property without the former co-heirs’ consent, subject to matters such as:

Registration and title status;
Estate and transfer taxes;
Existing mortgages, liens, adverse claims, leases, or court orders;
Spousal consent when required by the seller’s own property regime;
Rights of persons in possession; and
Restrictions affecting agricultural, agrarian-reform, homestead, socialized-housing, or similarly regulated property.

The partition itself must be legally effective. An informal family understanding about who “uses” each area is not always equivalent to a valid, registrable partition.

Extrajudicial settlement is not a shortcut around an unwilling or omitted heir

Under Section 1, Rule 74 of the Rules of Court, an estate may be settled extrajudicially when, among other requirements:

The decedent left no will;
The estate has no outstanding debts, subject to the rule’s stated presumption;
All heirs are of age, or minors are properly represented by judicial or legal representatives duly authorized for the purpose;
The heirs agree on the settlement;
The settlement is made in a public instrument and filed with the Register of Deeds when real property is involved;
The required bond concerning personal property is filed; and
The fact of settlement is published as required by the rule.

If there is only one heir, that heir may use an affidavit of self-adjudication when the legal conditions are satisfied.

An extrajudicial settlement is not binding on a person who did not participate in it or had no notice. The Supreme Court has also explained that Rule 74’s two-year provision cannot simply be used to defeat an omitted heir when the rule’s requirements were not strictly followed. See Rule 74 of the Rules of Court and Treyes v. Antonio, G.R. No. 204739, September 8, 2020.

If the heirs cannot agree, the ordinary remedy is usually judicial settlement or partition—not an extrajudicial deed signed by fewer than all the required parties.

The other heirs may have a right of legal redemption

When an heir sells hereditary rights to a stranger before partition, Article 1088 allows any or all co-heirs to take the buyer’s place by reimbursing the purchase price.

The co-heir must exercise this right within one month from written notice of the completed sale given by the selling heir. The notice should disclose the actual sale and its material terms; advance notice of a proposed transaction is not the same as notice of a completed sale.

The Supreme Court emphasized the written-notice requirement in Primary Structures Corporation v. Valencia, G.R. No. 150824, August 19, 2003 and Garcia v. Calaliman, G.R. No. 156536, October 31, 2006.

After an ordinary co-ownership has been established, Articles 1620 and 1623 may also govern legal redemption when a co-owner’s share is sold to a third person. Article 1623 provides a 30-day period from written notice and requires an affidavit of notice before the deed may be recorded. The Supreme Court reaffirmed the mandatory nature of written notice in Heirs of Alido v. Campano, G.R. No. 259662, April 23, 2025.

Because the applicable provision can depend on whether the estate remains unpartitioned, affected parties should not wait to determine which redemption rule controls.

What if an heir refuses to sell or partition?

No co-owner is ordinarily required to remain indefinitely in a co-ownership. Articles 494 and 1083 of the Civil Code generally allow a co-owner or co-heir to demand partition, subject to valid temporary agreements, a testator’s lawful prohibition, and other statutory exceptions.

Available routes include:

Negotiated partition. The heirs agree which assets or portions go to each person.
Buyout. One or more heirs purchase the others’ shares at an agreed value.
Sale by agreement. Everyone sells the whole property and divides the net proceeds according to their lawful shares.
Judicial partition. An heir files an action under Rule 69 when agreement is impossible.
Estate administration or probate. This may be necessary when there is a will, unsettled debt, disputed heirship, missing property, or another issue requiring court supervision.

If the property is indivisible or physical division would seriously impair its value, it may be assigned to one heir who pays the others the appropriate amount. If the conditions under Article 1086 apply and an heir demands it, sale at public auction with participation by strangers may be required.

A partition case must generally include all persons with an interest in the property. Venue, jurisdiction, prior barangay conciliation, and the need for estate proceedings depend on the parties and facts.

Practical steps before anyone signs a sale

1. Confirm what the decedent actually owned

Obtain and examine:

A certified true copy of the transfer certificate of title, condominium certificate of title, or original certificate of title;
The tax declaration and latest real-property-tax records;
The deed by which the decedent acquired the property;
Any mortgage, adverse claim, notice of lis pendens, lease, annotation, or restriction;
Survey plans and technical descriptions; and
Documents showing whether the land is agricultural or subject to a government award or restriction.

The name on a tax declaration alone is not conclusive proof of ownership.

2. Identify every lawful heir and the correct shares

Collect civil-registry records such as:

Death certificate;
Birth certificates;
Marriage certificates;
Adoption records, if applicable;
The will and probate records, if a will exists; and
Death certificates of heirs who died after the original owner.

Do not assume that only the children inherit. A surviving spouse, descendants, parents, acknowledged nonmarital children, substitute heirs, or heirs of a child who died may affect the shares. The result depends on the family structure, dates of death, legitimacy or filiation evidence, renunciations, and any valid will.

3. Separate the surviving spouse’s property from the estate

A title in the decedent’s name—or in the spouses’ names—does not by itself establish that the entire property belongs to the estate. The marital property regime must first be examined and, when required, liquidated.

The decedent’s estate includes only the decedent’s lawful interest. A surviving spouse may separately own a share before receiving any inheritance from the decedent.

4. Check whether the estate has been legally settled

Look for:

A probated will;
Letters testamentary or letters of administration;
A court-approved project of partition;
A registered extrajudicial settlement;
An affidavit of self-adjudication;
Prior deeds of sale or assignment;
The new or annotated titles; and
Proof of publication, tax clearance, and registration.

Do not rely solely on photocopies or an heir’s claim that “the family already divided it.”

5. Define exactly what is being sold

The deed should make clear whether the transaction covers:

The seller’s hereditary rights in the estate;
A stated undivided interest in a particular property;
A specific property already awarded in partition; or
The entire property with the participation of all owners.

Avoid describing an unpartitioned hereditary share as an exclusive, surveyed portion unless the legal basis for that physical allocation has been verified.

6. Complete the tax and registration process

Estate tax obligations generally must be addressed before inherited real property can be transferred through the Registry of Deeds. Under the Tax Code as amended by the TRAIN Law, an estate-tax return is generally due within one year from death, although authorized extensions or installment arrangements may apply in qualifying cases.

A later sale may also generate capital-gains tax or other income tax, documentary stamp tax, withholding obligations, local transfer tax, registration fees, and certification requirements. Classification of the property as a capital or ordinary asset materially changes the tax treatment.

For current requirements and filing channels, consult the BIR estate-tax guidance, BIR capital-gains-tax guidance, and the relevant Revenue District Office. Requirements of the Registry of Deeds and local treasurer should also be confirmed before signing because documentary and procedural requirements can vary with the transaction.

Evidence to preserve if a sale is disputed

Keep originals or reliable copies of:

The questioned deed and every page, acknowledgment, attachment, and notarial detail;
Written notices of sale and proof of receipt;
Messages, emails, letters, advertisements, and offers;
Receipts, bank transfers, checks, escrow records, and proof of the true price;
Titles obtained before and after the transaction;
Registry of Deeds certified copies and entry records;
Tax returns, electronic Certificates Authorizing Registration, and payment confirmations;
Estate-settlement, publication, and court records;
Powers of attorney and identification documents used at signing;
Specimen signatures and evidence relevant to an alleged forgery;
Photographs, surveys, possession records, leases, harvest records, and rent receipts; and
Names and contact details of witnesses, the notary, broker, surveyor, and occupants.

Request certified records promptly. Titles can be transferred again, witnesses become difficult to locate, and electronic communications may be deleted.

Common mistakes

Believing that possession of the owner’s duplicate title allows one heir to sell the whole property;
Assuming the heir who paid taxes, maintained the land, or lived there automatically became sole owner;
Treating an informal family allocation as a completed legal partition;
Omitting a surviving spouse, nonmarital child, adopted child, minor, or branch of a deceased heir;
Signing an extrajudicial settlement stating that there are no other heirs when that is untrue;
Buying a precisely described corner of an unpartitioned lot from only one heir;
Paying the full price before verifying heirship, title, taxes, and registration feasibility;
Using a general power of attorney when a special authority to sell is required;
Confusing Rule 74’s two-year liability period with a universal deadline that automatically validates an invalid settlement;
Ignoring the co-heirs’ possible legal-redemption rights;
Assuming notarization proves ownership or cures lack of authority; and
Delaying action after receiving written notice of a sale.

When legal help is urgent

Consult a Philippine lawyer promptly if:

Written notice of a sale has been received and legal redemption is being considered;
A deed, affidavit of self-adjudication, extrajudicial settlement, or new title omits an heir;
A signature appears forged or was obtained through deception;
The buyer is attempting to evict occupants, fence a specific area, demolish a home, or resell the property;
A title-transfer application is pending;
A court summons, demand letter, notice of adverse claim, or notice of lis pendens has been received;
A minor’s or legally incapacitated person’s share is involved;
The property belonged to a deceased married owner but the marital estate was never liquidated;
There is a will, an unsettled estate debt, disputed filiation, or conflicting settlement documents;
The land is covered by agrarian-reform, tenancy, homestead, ancestral-domain, socialized-housing, or government-award restrictions; or
The seller or buyer is abroad and powers of attorney or consular formalities are involved.

Possible remedies may include legal redemption, partition, estate settlement, reconveyance, annulment or partial invalidation of a deed, cancellation or correction of title, accounting, damages, an adverse claim, or provisional court relief. The proper remedy and filing deadline depend on the documents and facts.

FAQ

Can one heir sell an inherited house without the others signing?

The heir may generally sell only that heir’s undivided interest. Selling the entire house requires the consent or lawful authority of all persons whose shares are being transferred. The buyer of one heir’s share becomes a co-owner and does not automatically obtain exclusive ownership or possession of the house.

Can the eldest child sell the property for the family?

Not merely because the child is the eldest, holds the title, pays the taxes, or acts as family representative. The child needs ownership of the interest being sold or valid authority from the other owners.

What if the deed says the seller owns the entire property?

That statement does not create ownership the seller does not possess. The transaction may operate only over the seller’s lawful interest, subject to the precise facts and the deed’s validity.

Can a buyer choose the seller’s portion of the land?

Not before partition. A buyer of an undivided share generally acquires an interest throughout the property and must await or participate in partition. A specific area sold without the other co-owners’ consent is subject to what is ultimately allotted to the seller.

Can the other heirs cancel the whole sale?

They may challenge any purported transfer of their shares. But if the seller validly transferred the seller’s own undivided interest, the transaction may remain effective to that extent. Cancellation, reconveyance, partition, or another remedy must be matched to the deed and circumstances.

Can the heirs redeem the share sold to an outsider?

Potentially. Article 1088 gives co-heirs a one-month period from written notice of the completed sale of hereditary rights before partition. Articles 1620 and 1623 may govern an ordinary co-owner’s sale and provide a 30-day period from written notice. Immediate advice is important because the applicable characterization and deadline can be contested.

Does publication of an extrajudicial settlement cure the omission of an heir?

No. Publication does not automatically make an extrajudicial settlement binding on an heir who did not participate and had no notice. It also does not cure a false declaration about the heirs.

What if all heirs agree except one?

The agreeing heirs cannot privately transfer the dissenting heir’s share. They may negotiate a buyout or pursue judicial partition or the appropriate estate proceeding.

Does an unnotarized sale transfer inherited land?

A sale of real property raises formal, enforceability, evidentiary, tax, and registration issues. Transfer of registered title requires proper instruments and registration requirements. Have the document reviewed rather than assuming that payment or a private writing conclusively settled ownership.
