In the Philippines, a prenuptial agreement—legally referred to as a Marriage Settlement—is a contract entered into by future spouses to fix the property regime that will govern their marriage. While often stigmatized, it is a practical legal tool designed to provide clarity and protect the individual interests of both parties before they enter a lifelong commitment.

The Legal Framework: The Family Code

Under the Family Code of the Philippines (Executive Order No. 209), if a couple does not execute a marriage settlement, the default property regime is Absolute Community of Property (ACP). Under ACP, all property owned by the spouses at the time of the celebration of the marriage or acquired thereafter is considered owned by both spouses in common.

By executing a prenuptial agreement, a couple can opt out of ACP and choose:

Conjugal Partnership of Gains (CPG): Only the fruits/income of individual properties and those acquired by effort during the marriage are shared.
Complete Separation of Property: Each spouse retains ownership and control over their respective past and future assets.
Any other regime: Provided it does not violate Philippine law or public policy.

Essential Requirements for Validity

For a prenuptial agreement to be legally binding and enforceable in the Philippines, it must strictly adhere to the following requirements set forth in Articles 75 to 77 of the Family Code:

In Writing: The agreement must be in a written instrument. Oral agreements regarding property settlements are void.
Signed Before the Marriage: The document must be executed and signed by both parties prior to the celebration of the marriage. Any modifications or agreements made after the wedding are generally invalid unless approved by a court during a petition for judicial separation of property.
Voluntary Consent: Both parties must enter the agreement freely, without force, intimidation, or undue influence.
Not Contrary to Law: Provisions must not violate public policy. For instance, a clause waiving the obligation of mutual support or a clause allowing infidelity would be considered void.

Formalities for Third-Party Binding

While a signed and notarized document is valid between the spouses, it must meet additional criteria to affect third parties (such as creditors):

Public Instrument: The document must be notarized.
Registration: The agreement must be registered in the Local Civil Registry where the marriage is recorded and in the Registry of Deeds in the province or city where the properties are located.

Estimated Legal Fees and Costs

The cost of drafting and finalizing a prenuptial agreement in the Philippines varies significantly based on the complexity of the assets involved and the seniority of the legal counsel.

1. Attorney’s Fees

Lawyers typically charge based on the volume of assets to be listed and the intricacy of the conditions.

Drafting Fee: For a standard "Separation of Property" agreement, fees often range from ₱20,000 to ₱100,000+.
Consultation/Acceptance Fees: Some firms charge a separate fee for the initial assessment and negotiations between the parties.

2. Notarial Fees

Since the document must be a public instrument, it must be notarized.

Notarial fees are often a percentage of the total value of the properties declared in the agreement (typically 0.1% to 1%), though many lawyers may agree to a fixed high-value fee for high-net-worth individuals.

3. Registration and Documentation Costs

Registry of Deeds: Fees are calculated based on a schedule provided by the Land Registration Authority (LRA), often tied to the assessed value of the real estate properties involved.
Local Civil Registrar: A nominal filing fee is required to attach the settlement to the marriage certificate records.
Documentary Stamp Tax (DST): Depending on the nature of property transfers (if any are stipulated within the agreement), DST may apply.

Key Clauses to Include

A comprehensive Philippine prenuptial agreement should detail:

Inventory of Assets: A complete list of real estate, bank accounts, stocks, and businesses owned prior to marriage.
Liability for Debts: Clear stipulations that debts incurred prior to the marriage remain the sole responsibility of the debtor spouse.
Future Inheritances: Explicitly stating that properties inherited during the marriage remain exclusive property.
Management and Administration: Who has the right to manage, encumber, or sell specific assets.
