Legal Guide to Prenuptial and Cohabitation Agreements in the Philippines

In the Philippine legal system, property relations between spouses and partners are governed primarily by Executive Order No. 209, otherwise known as the Family Code of the Philippines. Understanding the nuances of prenuptial and cohabitation agreements is essential for protecting individual assets and ensuring clarity in the event of legal separation, annulment, or death.


I. Prenuptial Agreements (Marriage Settlements)

A prenuptial agreement, legally referred to as a Marriage Settlement, is a contract entered into by future spouses before the celebration of marriage. Its primary purpose is to fix the property regime that will govern their union.

1. Requisites for Validity

For a marriage settlement to be valid and enforceable under Philippine law, it must meet the following criteria:

  • Timing: It must be executed before the celebration of the marriage.
  • Form: It must be in writing.
  • Execution: It must be signed by both parties.
  • Modifications: Any changes to the settlement must also be made before the wedding. Post-marriage modifications generally require judicial intervention and are only allowed in specific cases like judicial separation of property.

2. Registration for Third-Party Binding

While a signed agreement is binding between the spouses, it does not affect third parties (such as creditors) unless it is:

  1. Notarized; and
  2. Registered in the local civil registry where the marriage is recorded and in the proper Registry of Property.

3. Default and Optional Property Regimes

If no prenuptial agreement is executed, the law automatically imposes a default regime based on the date of the marriage:

  • Marriages on or after August 3, 1988: Absolute Community of Property (ACP).
  • Marriages before August 3, 1988: Conjugal Partnership of Gains (CPG).

Common Regimes Chosen in Prenuptial Agreements:

Regime Description
Complete Separation of Property Each spouse retains ownership, management, and enjoyment of their respective past and future assets.
Conjugal Partnership of Gains (CPG) Spouses retain ownership of properties brought into the marriage, but the "fruits" or income from those assets and everything acquired by chance or industry during the marriage go into a common fund.
Absolute Community of Property (ACP) All property owned by the spouses at the time of marriage and those acquired thereafter become part of a single common pool, with limited exceptions.

II. Property Relations in Cohabitation (Common-Law Unions)

In the Philippines, "cohabitation" refers to a man and a woman living together as husband and wife without the benefit of marriage. The property rules for these unions are divided into two categories under the Family Code.

1. Unions Without Legal Impediment (Article 147)

This applies to partners who are both legally capacitated to marry each other (e.g., both are single, of legal age, and not closely related) but choose not to marry.

  • Ownership Rule: Salaries and wages are owned in equal shares.
  • Property Acquired Through Joint Effort: Properties acquired during the cohabitation are presumed to be owned in equal shares.
  • The "Household Management" Clause: If one party did not have an income but took care of the household and the family, the law considers this a contribution through "joint effort," granting them an equal share in the properties acquired by the other.
  • Disposal: Neither party can sell or encumber their share in the common property inter vivos (during their lifetime) without the other's consent until the union is terminated.

2. Unions With Legal Impediment (Article 148)

This applies to "adulterous" or "bigamous" relationships, or unions where the parties cannot marry due to legal barriers (e.g., one party is still legally married to someone else).

  • No Presumption of Equality: Only the property acquired by both parties through their actual joint contribution of money, property, or industry shall be owned by them in common.
  • Actual Contribution Required: Unlike Article 147, "care and maintenance of the family and household" does not count as a contribution.
  • Proof of Contribution: If a party cannot prove their actual contribution, the property is deemed owned by the party who has the income or the means to acquire it.
  • Forfeiture: If one party is validly married to someone else, their share in the cohabitation property may be forfeited in favor of the legal conjugal partnership.

III. Key Comparison: Prenup vs. Cohabitation

Feature Prenuptial Agreement Cohabitation (Art. 147/148)
Legal Basis Contractual agreement via Family Code. Statutory rules (operation of law).
Flexibility High (parties can customize their rules). Low (rules are fixed by the Code).
Household Care Can be defined by the parties. Recognized as contribution only in Art. 147.
Registration Required for third-party notice. Not applicable; based on proof of acquisition.

IV. Legal Limitations and Prohibitions

Despite the freedom to contract in a prenuptial agreement, certain provisions are considered void in the Philippines:

  1. Waiver of Support: Spouses cannot validly waive the right to future support.
  2. Agreement to Separate: A provision that mandates a "legal separation" or "divorce" (which is currently not recognized for non-Muslims) is void.
  3. Transfer of Parental Authority: Rights and duties regarding children cannot be signed away or altered by a prenuptial contract.
  4. Contravention of Law/Morals: Any clause that violates public policy or mandatory provisions of the Civil Code/Family Code is unenforceable.

In the absence of a written agreement, the state effectively "writes the contract" for the couple through the default provisions of the Family Code. Therefore, legal counsel is typically sought to ensure that pre-existing family wealth, inheritance, and personal earnings are protected through a validly executed and registered Marriage Settlement.
