A co-heir may sell his or her own undivided hereditary share in inherited land without obtaining the other heirs’ consent. However, that co-heir generally cannot sell the entire property, bind the shares of the other heirs, or guarantee ownership of a specific physical portion before the estate is properly partitioned. The buyer normally acquires only whatever share legally belongs to the seller and may also face the other heirs’ statutory right of redemption.

Why inherited land belongs to all the heirs before partition

Under Article 777 of the Civil Code of the Philippines, succession rights are transmitted from the moment of the owner’s death. The heirs do not need to wait for the title to be transferred before hereditary rights arise.

However, when there are two or more heirs, Article 1078 provides that the decedent’s estate is owned in common by them before partition, subject to the payment of the decedent’s debts. This arrangement is called co-ownership. (Lawphil)

For example, suppose a mother dies leaving a 600-square-meter lot to four children in equal shares. Before partition:

Each child has an ideal one-fourth interest in the property.
No child automatically owns the front, back, left, or right 150 square meters.
The heirs collectively own the entire lot, while each heir holds an undivided percentage.
The estate’s debts, taxes, and legitimate claims must still be considered.

An undivided share is a percentage or fractional interest that has not yet been converted into a separately identified physical area.

Can one heir sell inherited land without the others signing?

The answer depends on what the heir is attempting to sell.

Proposed transaction	Is the other heirs’ consent required?	Legal effect
Sale of the heir’s undivided hereditary share	Generally no	Buyer acquires only the seller’s lawful share
Sale of the entire inherited property	Yes, if the buyer expects to acquire the whole property	Sale cannot bind the shares of non-signing heirs
Sale of a specific physical area before partition	Other heirs’ consent or a valid partition is normally needed for certainty	Sale remains subject to the result of partition
Sale of property exclusively awarded to the heir after partition	No, subject to title, marital-property, tax, and other legal requirements	Heir may sell as exclusive owner
Sale signed by all heirs after estate settlement	Yes, all owners must participate	Buyer may acquire the entire property

Article 493 of the Civil Code allows each co-owner to alienate, assign, or mortgage his or her share. But the effect of the transaction is limited to the portion eventually allotted to that co-owner when the co-ownership ends. (Lawphil)

Selling an undivided share

A co-heir may execute a deed selling or assigning a fractional interest, such as:

“My undivided one-fourth hereditary interest in the property covered by TCT No. _____.”

The buyer steps into the seller’s position as co-owner. The buyer does not automatically receive exclusive possession of a chosen corner of the property.

The Supreme Court confirmed in Heirs of Caburnay v. Heirs of Sison, G.R. No. 230934, December 2, 2020, that a co-owner does not need the other co-owners’ consent to alienate an undivided share. Even when a co-owner purports to sell the whole property, the transfer may remain effective only to the extent of that seller’s lawful interest. (Supreme Court E-Library)

Selling a specific portion before partition

A deed stating that one heir sold “the rear 300 square meters” is legally risky when the estate has never been partitioned.

Before partition, the selling heir ordinarily does not own that exact rear portion. The deed may be recognized only to the extent of the seller’s undivided share, and the buyer must accept the result of the eventual partition.

In Tabasondra v. Spouses Constantino, G.R. No. 196403, December 7, 2016, the Supreme Court recognized an heir’s right to sell her pro indiviso or undivided share. However, because the property had not been partitioned, no particular physical portion could yet be identified as the exclusive object of the sale. (Supreme Court E-Library)

Selling the entire land while other heirs do not consent

One heir cannot transfer ownership of shares belonging to the other heirs.

If a son owns only one-fourth of inherited land but signs a deed stating that he is selling the entire property, the buyer generally acquires no more than the son’s actual one-fourth interest. The remaining three-fourths continues to belong to the other heirs.

The Supreme Court applied this principle in Heirs of Bandoy v. Bandoy, G.R. No. 255258, October 19, 2022, ruling that a sale of portions of inherited property was valid only insofar as the seller’s aliquot or fractional share in the estate was concerned. (Supreme Court E-Library)

Does the buyer become the owner of the land?

The buyer becomes a co-owner only to the extent of the seller’s valid share.

The buyer may:

Participate in the co-ownership.
Receive the fruits or income attributable to the acquired share.
Join negotiations for voluntary partition.
Ask for judicial partition if no agreement is possible.
Sell or transfer the acquired undivided interest, subject to applicable legal restrictions.

The buyer generally may not:

Fence off a chosen area as exclusively his or hers without partition or agreement.
Remove the other heirs from the property merely because one heir signed a deed.
Build, demolish, subdivide, or substantially alter the common property without respecting the rights of the other co-owners.
Demand a physical portion greater than the share acquired.
Obtain ownership rights that the selling heir never possessed.

Article 494 provides that no co-owner is ordinarily required to remain indefinitely in a co-ownership. Any co-owner, including a buyer who acquired an heir’s share, may demand partition. If the property is indivisible and the parties cannot agree that one owner will keep it while paying the others, Articles 495 and 498 allow the co-ownership to be terminated through a sale and distribution of the proceeds. (Lawphil)

Can the other heirs redeem the share that was sold?

In many cases, yes.

Redemption before partition under Article 1088

Article 1088 of the Civil Code applies when:

There are several heirs.
The estate has not yet been partitioned.
One heir sells his or her hereditary rights.
The buyer is a stranger to the inheritance, meaning someone who is not a co-heir.
One or more co-heirs reimburse the buyer within one month from written notice of the sale by the selling heir.

This is called legal redemption. It allows a co-heir to take the buyer’s place under the same sale by reimbursing the purchase price. (Lawphil)

The short redemption period normally begins only after proper written notice. In Escabarte v. Heirs of Isaw, G.R. No. 208595, August 28, 2019, the Supreme Court explained that written notice identifies the precise date when the redemption period begins. Actual knowledge does not automatically replace the required written notice in ordinary circumstances, although exceptional facts may affect how the rule is applied. (Lawphil)

A prudent written notice should include:

The date of the sale.
The buyer’s full name.
The share sold.
The purchase price.
Material payment terms.
A copy of the signed deed.
Proof that each co-heir received the notice.

Registered mail, personal delivery with a signed acknowledgment, or another method that clearly proves the date of receipt is preferable to an informal text message.

Redemption after partition or ordinary co-ownership

When the heirs are already treated as ordinary co-owners rather than merely co-heirs before partition, Articles 1620 and 1623 may apply. A co-owner may redeem a share sold to a third person within 30 days from written notice.

Article 1623 also requires an affidavit that written notice was given to possible redemptioners before the deed is recorded in the Registry of Property. (Lawphil)

The distinction matters:

Situation	Main provision	Redemption period
Sale of hereditary rights to a stranger before partition	Article 1088	One month from written notice by the vendor
Sale of a co-owner’s share under ordinary co-ownership	Articles 1620 and 1623	30 days from written notice

A sale to another co-heir generally does not trigger Article 1088 because the buyer is not a stranger to the inheritance.

What should the other heirs do if the land was already sold?

1. Obtain the relevant documents

Secure certified or authenticated copies of:

The current Transfer Certificate of Title or Original Certificate of Title.
The deed of sale, assignment, or extrajudicial settlement.
Any new title issued after the transaction.
The tax declaration.
The owner’s death certificate.
Birth and marriage records establishing the heirs.
The will and probate records, if any.
BIR electronic Certificate Authorizing Registration or eCAR documents.
Written notices allegedly sent to the heirs.
Receipts, proof of payment, and records of possession.

Do not rely only on a photocopy supplied by the buyer or selling heir. A certified true copy of the title from the Registry of Deeds will show registered owners and material annotations.

2. Determine the seller’s true hereditary share

The share cannot always be calculated simply by dividing the property by the number of children. It may depend on:

Whether there is a surviving spouse.
Whether the land was exclusive, conjugal, or community property.
Whether the decedent left legitimate, illegitimate, or adopted children.
Whether representation applies because an heir died earlier.
Whether there is a valid will.
Whether donations must be brought into collation.
Whether compulsory heirs’ legitimes were impaired.
Whether the seller had previously assigned or waived rights.

The surviving spouse’s ownership share in marital property must first be separated from the decedent’s estate. Only the decedent’s portion is distributed through succession.

3. Check whether the redemption period has started

Look for actual written notice from the seller and proof of delivery. Registration of the deed, verbal information, family gossip, or seeing a buyer on the property does not necessarily establish the date required by Article 1088.

Because the statutory period is very short, an heir intending to redeem should document the offer to reimburse and be ready to tender the purchase price.

4. Send a formal objection or redemption notice

Depending on the facts, the heir may send:

A written notice exercising legal redemption.
A demand that the buyer recognize only the seller’s undivided share.
A demand to stop fencing, construction, demolition, or exclusion of co-owners.
A proposal for voluntary partition or buyout.
A request for accounting of rent, harvests, or other income.

The communication should identify the property, title number, deed, parties, claimed hereditary share, and specific relief requested.

5. Use barangay conciliation when legally required

Prior barangay conciliation may be a condition before filing a civil action when the individual parties actually reside in the same city or municipality and the dispute falls within the authority of the Katarungang Pambarangay. Real-property disputes are generally brought before the barangay where the property or its larger portion is located, subject to statutory exceptions.

Failure to complete mandatory barangay proceedings can make a court complaint vulnerable to dismissal for prematurity, although the requirement may be waived if not timely raised. (DILG)

6. File the appropriate court action when necessary

Depending on the documents and relief needed, possible actions include:

Judicial partition.
Annulment or declaration of nullity of a deed.
Reconveyance.
Quieting of title.
Cancellation or correction of a title.
Accounting of income and expenses.
Recovery of possession.
Damages.
Injunction against an imminent transfer, construction, or dispossession.

A real action involving land is generally filed in the proper trial court covering the place where the property is located. Court jurisdiction may depend on the property’s assessed value and the specific relief requested.

How heirs can properly sell inherited land

The cleanest approach is to settle and partition the estate before selling the whole property or a specific portion.

1. Confirm the complete list of heirs

Collect PSA-issued civil registry documents and determine whether the deceased left a will. A valid will must generally undergo probate before its provisions can be implemented.

2. Check the title and property status

Verify:

Registered owner.
Mortgages, liens, adverse claims, and notices of lis pendens.
Tax declarations and unpaid real property taxes.
Road access and boundary issues.
Agricultural classification.
Agrarian-reform annotations, emancipation patents, or Certificates of Land Ownership Award.
Pending cases involving the property.

Agricultural and agrarian-reform land may be subject to separate transfer restrictions and Department of Agrarian Reform requirements.

3. Settle the estate

An extrajudicial settlement under Rule 74 may generally be used when:

The deceased left no will.
There are no outstanding estate debts, or the debts have been paid.
All heirs are of legal age, or minors are properly represented.
The heirs agree on the settlement.
A public instrument is executed and filed with the Registry of Deeds.
The required newspaper publication is completed.

The settlement is normally published once a week for three consecutive weeks in a newspaper of general circulation. An extrajudicial settlement cannot bind an heir who did not participate and had no notice. Publication does not give the signing heirs ownership of an excluded heir’s share. (Lawphil)

A person may execute an Affidavit of Self-Adjudication only when that person is genuinely the sole heir. Using self-adjudication when other heirs exist can lead to cancellation of the resulting title and other civil or criminal consequences.

If the heirs cannot agree, judicial settlement or judicial partition may be necessary.

4. Pay estate taxes and obtain the eCAR

Estate tax and sale taxes are separate obligations.

For deaths on or after January 1, 2018, Republic Act No. 10963 or the TRAIN Law generally imposes estate tax at 6% of the net taxable estate. The law applicable on the date of death governs older estates. The BIR’s eCAR serves as authority for registration and distribution of inherited property. (Lawphil)

The extended estate tax amnesty ended on June 14, 2025. Estates that did not qualify or avail before that deadline may be subject to the estate tax law applicable at the time of death, together with applicable interest and penalties. (Bir Cdn)

Common BIR documents include:

Certified death certificate.
TINs of the decedent and heirs.
Estate tax return.
Extrajudicial settlement, court order, or other proof of settlement.
Certified title and tax declaration.
Property valuation records.
Proof of deductions and debts, when claimed.
Proof of payment.
Valid identification and authority of the representative.

The current documentary checklist should be confirmed through the BIR Estate Tax information page.

5. Partition or clearly identify what is being sold

The heirs may:

Subdivide the property and assign separate lots.
Award the whole property to one heir, who pays the others.
Sell the whole property together and divide the net proceeds.
Keep the land co-owned but specify percentage interests.
Sell only one heir’s undivided share.

If land will be physically subdivided, survey work, subdivision plans, local approvals, and land-registration requirements may be necessary.

6. Prepare the correct deed

The document should accurately state whether the transaction covers:

The entire property.
A separately titled lot.
An undivided co-ownership share.
Hereditary rights before partition.
Rights combined with an extrajudicial settlement.

Describing an undivided interest as a definite physical lot creates avoidable disputes.

7. Give written notice to possible redemptioners

When legal redemption may apply, the seller should provide written notice containing the complete terms of sale and preserve reliable proof of receipt.

8. Pay transfer taxes and register the transaction

Depending on the transaction, costs may include:

Estate tax and penalties.
Capital gains tax or creditable withholding tax.
Documentary stamp tax.
Local transfer tax.
Real property tax arrears.
Registration fees.
Notarial fees.
Publication costs.
Survey and subdivision expenses.

For an individual selling Philippine real property classified as a capital asset, the usual capital gains tax is 6% of the higher of the gross selling price or applicable fair market value. Different rules apply when the property is an ordinary asset or when the transaction is an assignment of hereditary rights rather than a straightforward registered-land sale. (Lawphil)

Special issues for heirs living abroad and foreign buyers

An heir abroad may authorize someone in the Philippines through a Special Power of Attorney. A Philippine consular officer may notarize the document. Alternatively, a document notarized in a country covered by the Apostille Convention is generally apostilled by the competent authority of that country. Documents from non-Apostille countries may require Philippine consular authentication. (Philippine Embassy in New Delhi)

A foreign national may inherit Philippine private land through hereditary succession. However, Article XII, Section 7 of the 1987 Constitution generally prohibits the transfer of private land to persons who are not legally qualified to acquire land, except through hereditary succession. (Lawphil)

This creates an important distinction:

A foreign spouse or child may inherit Philippine land as a lawful heir.
A foreigner who is not inheriting generally cannot buy an heir’s land share.
A foreign heir ordinarily cannot purchase the other heirs’ shares merely to consolidate full ownership, because that additional acquisition is by sale, not hereditary succession.
Former natural-born Filipinos may acquire private land subject to constitutional and statutory limits.

Common mistakes that cause inheritance disputes

Treating a percentage share as a physical area

A one-third hereditary share does not automatically mean a particular one-third section of the lot.

Allowing one sibling to sign for everyone

Family seniority, possession of the title, payment of taxes, or management of the property does not automatically authorize one heir to sell the others’ shares.

Signing a blank or vaguely worded SPA

An SPA should specifically identify the property and authorized acts. Authority to “process documents” does not necessarily include authority to sell, set the price, receive payment, or waive hereditary rights.

Believing newspaper publication cures an excluded heir

Publication is required for an extrajudicial settlement, but it does not validate the deprivation of a known heir who did not participate or receive notice.

Paying the seller before checking the title and heirs

A buyer should verify civil registry records, the death of prior owners, every estate settlement in the chain of title, possession of the land, and possible unregistered heirs.

Assuming tax-declaration ownership is the same as registered ownership

A tax declaration is evidence relating to possession and taxation, but it is not equivalent to a Torrens title.

Ignoring earlier generations of unsettled estates

Some Philippine properties remain titled in the name of a grandparent or great-grandparent. Each deceased owner’s estate may require a separate settlement, estate-tax computation, and supporting set of civil registry documents.

Frequently Asked Questions

Can one sibling sell inherited property without my signature?

The sibling may generally sell only his or her undivided hereditary share. Your signature is required if the transaction is intended to transfer your share or the entire property.

Is the sale automatically void if the other heirs did not consent?

Not necessarily. The sale may remain valid to the extent of the seller’s actual share while being ineffective against the shares of the non-consenting heirs.

Can the buyer take possession of a specific part of the land?

Not as exclusive owner merely because the deed describes a specific area. Before partition, the buyer normally owns an undivided share and must respect the possession and ownership rights of the other co-owners.

Can the other heirs cancel the sale?

They may challenge the deed insofar as it covers their shares, seek reconveyance or title correction, demand partition, or exercise legal redemption when the requirements are present. The proper remedy depends on the deed, title history, notice, possession, and timing.

How long do heirs have to redeem a sold hereditary share?

Under Article 1088, co-heirs generally have one month from written notice by the selling heir. Under Articles 1620 and 1623, ordinary co-owners generally have 30 days from written notice.

What happens if the selling heir never gave written notice?

As a general rule, the statutory redemption period may not have started. The facts must still be reviewed because actual knowledge, prior proceedings, admissions, delay, or exceptional circumstances can affect the dispute.

Can an heir sell rights while the title is still in the deceased parent’s name?

A transfer of hereditary rights may be contractually valid, but registration and issuance of a title to the buyer can be delayed until heirship, estate settlement, estate taxes, and BIR and Registry of Deeds requirements are completed.

What if one heir refuses to sign the extrajudicial settlement?

An extrajudicial settlement by agreement cannot ordinarily be completed as though the refusing heir did not exist. The heirs may negotiate a buyout or voluntary partition. Otherwise, judicial settlement or partition may be required.

Can a foreigner buy one heir’s share?

Generally not, because purchasing a share is a transfer by sale rather than hereditary succession. A foreigner may inherit Philippine private land but is ordinarily constitutionally disqualified from purchasing private land.

How long does the process usually take?

A cooperative extrajudicial settlement may take several months after document collection, three-week publication, BIR processing, tax payment, local clearances, and registration. Missing records, multiple deceased owners, heirs abroad, disputed filiation, unpaid taxes, or title defects can extend the process considerably. A contested judicial partition can take years.

Key Takeaways

A co-heir may generally sell only his or her undivided hereditary share without the other heirs’ consent.
One heir cannot validly transfer the shares belonging to the other heirs.
Before partition, an heir ordinarily cannot guarantee ownership of a particular physical section of the land.
The buyer usually becomes a co-owner and acquires no greater right than the selling heir possessed.
Co-heirs may have a one-month right of redemption under Article 1088 after proper written notice.
A valid extrajudicial settlement normally requires the participation of all heirs and cannot bind an excluded heir who had no notice.
Estate tax settlement and a BIR eCAR are usually necessary before inherited land can be cleanly transferred and registered.
Foreigners may inherit Philippine private land but generally cannot buy additional land shares from co-heirs.
When the heirs cannot agree, judicial partition is the established method for ending the co-ownership.
