Which Country's Law Governs Your Matrimonial Property in Portugal?

Owning a home in Portugal does not automatically mean Portuguese matrimonial property law governs your whole marriage.

For international couples, the first legal question can be:

Which country's law actually governs the matrimonial property regime?

That law can determine how assets are classified, how debts are treated, what powers each spouse has over property and how the regime is liquidated.

The short answer

For couples within the applicable EU framework, Regulation (EU) 2016/1103 can determine the governing law.

The spouses may have made a valid choice of law.

If they did not, the Regulation uses a hierarchy that starts with the couple's first common habitual residence after marriage, then common nationality at marriage, then the State with which the couple jointly had the closest connection at that time.

The result may be Portuguese law.

It may also be the law of another country.

If Portuguese law governs the matrimonial property regime, the next step is to identify which Portuguese regime applies.

Matrimonial Property Regimes in Portugal for International Couples

A Portuguese property does not answer the question by itself

A couple can:

• marry in one country
• live first in another
• later move to Portugal
• own property in several countries
• have different nationalities

The location of one asset is therefore not a complete answer to the matrimonial-property question.

Under the EU Regulation, one applicable matrimonial-property law can govern the regime across assets regardless of where those assets are located.

That is designed to avoid a marriage having a different matrimonial regime for every country where the couple owns property.

Can spouses choose the applicable law?

Within the Regulation's scope, yes.

Spouses or future spouses can agree to designate or change the law governing their matrimonial property regime when the chosen law is:

• the law of the State where either spouse is habitually resident when the agreement is made; or
• the law of a State of nationality of either spouse when the agreement is made

A choice-of-law agreement has formal requirements. It is not simply an email saying "we prefer Portuguese law".

If you are combining a choice of law with a prenuptial or matrimonial-property agreement, the formal requirements need to be coordinated.

What happens if there is no choice of law?

For marriages within the Regulation's applicable-law temporal scope, the hierarchy is:

1. First common habitual residence after marriage

The first question is where the spouses established their first common habitual residence after the marriage.

That can be more important than where the ceremony took place.

2. Common nationality at the time of marriage

If there was no first common habitual residence, the next connecting factor is the spouses' common nationality when they married.

If the spouses had more than one common nationality, the Regulation contains a special rule and the ordinary common-nationality limb does not simply decide the question.

3. Closest connection at the time of marriage

If neither of the first two factors resolves the issue, the law of the State with which the spouses jointly had the closest connection at the time of marriage can apply.

This is fact-specific.

What does the applicable law actually govern?

The governing matrimonial-property law can determine, among other things:

• whether an asset is separate or common
• whether an asset can move from one category to another
• whether one spouse can be responsible for the other's liabilities and debts
• powers and obligations over property
• dissolution and partition of the matrimonial property regime
• effects against third parties within the Regulation's framework
• material validity of a matrimonial property agreement

That is why the applicable-law question comes before many asset-specific questions.

We married before 29 January 2019. Do these rules automatically apply?

Not necessarily.

The Regulation contains transitional provisions.

Its Chapter III applicable-law rules apply to spouses who marry or specify the applicable law to their matrimonial property regime on or after 29 January 2019.

If the marriage predates that date and the couple did not later make a choice that brings the case within the Regulation's applicable-law framework, older conflict-of-laws rules may need to be analysed.

Do not retroactively apply the 2019 hierarchy to every older international marriage.

Can we change the applicable law during marriage?

Within the Regulation's scope, spouses can make a later choice that satisfies Article 22.

Unless they agree otherwise, a change made during marriage operates prospectively.

A retroactive change cannot prejudice third-party rights.

That matters where the couple already has:

• property
• mortgages
• creditors
• company interests
• guarantees
• existing transactions

Does the same law govern inheritance if one spouse dies?

No.

This is one of the most important distinctions.

The matrimonial property regime determines what belongs to each spouse before the deceased's estate is calculated.

Succession is a separate legal layer.

Under the EU Succession Regulation, the default law for the succession as a whole is generally the law of the deceased's habitual residence at death, subject to the Regulation's rules and a valid nationality-based choice of law.

Example: married abroad, now living in Portugal

Suppose a couple:

• married abroad
• first lived together in Country A
• later moved to Portugal
• bought a Portuguese apartment

It is unsafe to conclude that Portuguese matrimonial property law automatically governs simply because the current home is in Portugal.

The first common habitual residence after marriage, any valid choice-of-law agreement and the Regulation's temporal rules may be decisive.

Example: different nationalities

A Portuguese citizen and a foreign citizen may marry and live in a third country.

Nationality alone does not automatically decide the matrimonial property regime.

The hierarchy and any valid choice need to be checked.

Why this matters before a property transaction

A property lawyer may need to know:

• who owns the asset economically
• which spouse has authority to sign
• whether spouse consent is required
• how the marriage regime should be described
• whether a foreign matrimonial regime must be evidenced

When legal review makes sense

Review the applicable law if:

• you and your spouse have different nationalities
• you married in one country and first lived together in another
• you moved countries after marriage
• the marriage predates 29 January 2019
• you signed a foreign prenup
• you own Portuguese real estate
• you own assets in several countries
• a divorce, inheritance or property sale is approaching

Need us to map the applicable law?

We can review the marriage date, nationalities, residence history, agreements and asset geography and identify the matrimonial-property framework that should be analysed.
