In Philippine civil law, a donation of property is a gratuitous contract whereby a person (donor) disposes of a thing or right in favor of another (donee) who accepts it. Once perfected and validly executed, a donation is generally irrevocable because it transfers ownership immediately. However, the law recognizes exceptional grounds for revocation or reduction to protect the donor, compulsory heirs, public policy, and the donee’s obligations. These rules apply primarily to donations inter vivos (made during the donor’s lifetime) of movable or immovable property. Donations mortis causa (made in contemplation of death) follow testamentary rules and are revocable by the donor at any time.

The governing statutes are the Civil Code of the Philippines (Republic Act No. 386), Book III, Title III, Chapters 1 to 4 (Articles 725–773), particularly Chapter 4 on Revocation and Reduction of Donations (Articles 760–773), and, for donations by reason of marriage (propter nuptias), the Family Code of the Philippines (Executive Order No. 209, as amended), Articles 81–86. Revocation is strictly construed; it is not favored and must be based on express statutory grounds. It is never automatic except in limited cases and almost always requires judicial action.

Distinction Between Revocation, Reduction, and Annulment

Revocation refers to the cancellation of a perfected and valid donation for causes arising after its execution (e.g., ingratitude or non-fulfillment of conditions). It restores the property to the donor or the donor’s estate.
Reduction is a partial revocation or diminution of the donation to the extent necessary to protect the legitime of compulsory heirs when the donation is inofficious (exceeds the disposable portion of the donor’s estate).
Annulment or rescission applies when the donation is void or voidable from the beginning (e.g., due to lack of capacity, formal defects, or fraud at execution). These are distinct from post-perfection revocation and are governed by Articles 1390–1405 (voidable contracts) and the specific formalities for donations under Articles 748–749.

Donations of immovable property require a public instrument and acceptance in the same or a separate public document (Article 749). Failure to comply renders the donation void, not merely revocable. Movable property donations may be oral or written depending on value.

Grounds for Revocation and Reduction

The Civil Code enumerates exhaustive grounds. No other causes exist unless the donor expressly reserves the right to revoke in the deed itself.

Acts of Ingratitude by the Donee (Article 765)
The donor may revoke the donation if the donee commits any of the following:
(1) An offense against the person, honor, or property of the donor, or of the donor’s spouse or children under the donor’s parental authority;
(2) Unjust imputation to the donor of any criminal offense or act involving moral turpitude, even if proven, unless the act was committed against the donee, the donee’s spouse, or the donee’s children; or
(3) Undue refusal to provide support to the donor when the donor is in manifest need of it.
This ground is personal and punitive. The action prescribes in one (1) year from the time the donor had knowledge of the act of ingratitude (Article 763). The donor’s heirs may continue an action already filed by the donor or, in certain cases, institute it themselves if the donor died before filing.
Non-Fulfillment of Conditions or Charges Imposed on the Donee (Article 764)
When the donation is modal or conditional (i.e., imposes a burden, charge, or suspensive/resolutory condition), failure of the donee to comply allows revocation. The donor (or the person in whose favor the condition was imposed) may demand performance or seek revocation. If the condition benefits a third person, that third person may also enforce it. Prescription is one (1) year from knowledge of non-fulfillment. Revocation restores the property free of the unperformed condition.
Appearance of Subsequent Children or Descendants (Article 760)
A donation inter vivos made by a person who, at the time of donation, had no legitimate, legitimated, or illegitimate children or descendants (or by an ascendant to a descendant) is presumed inofficious and subject to revocation or reduction if, afterward, the donor has:
- Legitimate or legitimated children or descendants;
- Illegitimate children or descendants;
- A child believed to be dead who is later found alive; or
- Adopts a child.
  The presumption protects future compulsory heirs. Reduction is proportionate among all donations (Article 761). The donee may retain enough to support himself and his family if the property is his only means of subsistence (Article 762).
Inofficious Donations Impairing Legitime (Articles 771, 911, and related provisions)
Donations that encroach upon the legitime of compulsory heirs (legitimate children/descendants, illegitimate children, surviving spouse, and ascendants in certain cases) are reducible after the donor’s death. Compulsory heirs may demand reduction or revocation to the extent necessary to complete their legitime. Collation (bringing back the value of the donation to the estate for computation) applies (Articles 1061–1075). This action is available only after the donor’s death and is distinct from the donor’s personal right to revoke during lifetime.
Special Grounds for Donations Propter Nuptias (Family Code, Article 86)
Donations made in consideration of marriage are revocable or reducible in these cases:
- The marriage is not celebrated or is declared void ab initio (except donations to common children or in good faith);
- The marriage is annulled and the donee-spouse acted in bad faith;
- Upon legal separation, if the donee-spouse is the offending party (donations to the innocent spouse remain valid).
  These rules also apply to voidable marriages under Article 45. Revocation may occur by operation of law upon final judgment of nullity or annulment.
Other Limited Grounds
- Express reservation of the right to revoke by the donor in the deed itself (allowed but must be clear).
- Donations mortis causa are revocable by the donor through a subsequent will or codicil, or by law (e.g., unworthiness of the donee-heir under Article 1027).
- Public policy or specific statutes may impose additional restrictions (e.g., donations to public officers under Article 739).

No revocation is allowed for mere change of mind or lack of consideration beyond the statutory causes.

Process for Revocation or Reduction

Revocation or reduction is judicial; the donor (or compulsory heirs) must file a civil action. Self-help or extrajudicial cancellation is invalid.

Who May File

During the donor’s lifetime: Primarily the donor (for ingratitude, non-fulfillment, or subsequent children).
After the donor’s death: Compulsory heirs for reduction of inofficious donations or continuation of pending revocation actions. The donor’s heirs may not initiate new ingratitude actions unless expressly reserved.
For propter nuptias: Either spouse or the innocent party, depending on the ground.

Court, Jurisdiction, and Venue

The action is filed in the Regional Trial Court (RTC) with jurisdiction over the donor’s or donee’s residence or where the property is located (for real property actions).
If the property value is below the threshold, Metropolitan Trial Court (MeTC)/Municipal Trial Court (MTC) jurisdiction may apply, but most property donations involve RTC.
The complaint must allege the specific statutory ground, attach the deed of donation, and pray for revocation, return of the property, accounting of fruits, and cancellation of title (if immovable).

Prescription Periods

Ingratitude or non-fulfillment: One (1) year from the donor’s knowledge of the cause (Article 763).
Subsequent children/inofficiousness during lifetime: Generally within the period for reduction actions (four years in some interpretations, but tied to knowledge).
Reduction after donor’s death: Within the prescriptive period for actions on succession (ten years under Article 1144 for real actions, but often five years from death in practice for collation).
Propter nuptias: Tied to the periods for annulment/nullity actions (e.g., five years for certain voidable marriages).

Procedure

Filing of verified complaint with docket fees and summons to the donee.
Donee’s answer; possible counterclaim for reimbursement of necessary expenses (Article 772).
Trial on the merits: Evidence must prove the ground (e.g., criminal conviction for offense, proof of need and refusal for support, birth certificates for subsequent children).
Judgment: If granted, the court orders return of the property, fruits from the date of filing (or earlier if bad faith), and cancellation of any title issued to the donee.
Execution and enforcement: Writ of execution; for immovable property, the judgment is registered with the Registry of Deeds to cancel the donee’s title and restore the donor’s or heirs’ title.

Effects of Revocation

Ownership reverts to the donor or estate as if the donation never occurred (subject to good-faith third-party buyers).
The donee must return the property and its accessions. If the donee is in bad faith, fruits from the date of donation are returnable; if in good faith, only from the filing of the action.
The donee may recover necessary expenses and improvements (with right of retention until reimbursed) but not useful expenses unless the donor elects to pay (Article 772).
If the property has been sold to a third person: The donor may recover its value from the donee if the buyer is in good faith.
Tax implications (donor’s tax already paid) may require refund claims with the Bureau of Internal Revenue, but this is collateral to the civil action.

Special Considerations

Donations Mortis Causa: Treated as wills; revocable by new testamentary disposition or by law (e.g., preterition, unworthiness). No need for revocation suit during donor’s life.
Public or Charitable Donations: May have additional restrictions under special laws; revocation is rarer and often requires governmental approval.
Good Faith Requirement: The donee’s good or bad faith affects liability for fruits and improvements.
Multiple Donees: Revocation affects all proportionally if the ground is common.
Jurisprudential Principles: Courts strictly construe revocation grounds to preserve the stability of ownership. The burden of proof lies on the party seeking revocation.

The rules on revocation balance the donor’s generosity with protection against ingratitude, future family needs, and the rights of compulsory heirs. They ensure that property donations remain instruments of liberality rather than tools for injustice. All actions must strictly comply with the Civil Code and Family Code provisions to be enforceable.
