Surviving Spouse Inheritance Rights in Portugal

A surviving spouse can have two different economic positions after a death:

• 1. property already belonging to the spouse through the matrimonial property regime;
• 2. inheritance rights in the deceased spouse's estate.

Do not calculate inheritance until those two layers are separated.

First: identify what actually belongs to the estate

Death ends the matrimonial property regime.

If the couple owned common property, the surviving spouse's own matrimonial share is not something they "inherit" from the deceased.

The estate then contains the deceased's separate assets and, where applicable, the deceased's share of common matrimonial property.

Only after that step do you calculate the inheritance.

This distinction can radically change the numbers.

Does Portuguese succession law apply?

Not automatically.

For international estates within the EU Succession Regulation, the default law governing the succession as a whole is generally the law of the deceased's habitual residence at death.

A person can also make a valid choice for the law of a State of their nationality to govern the succession.

So a Portuguese apartment does not by itself prove that Portuguese forced-heirship rules govern the entire estate.

If Portuguese succession law does apply, the rules below become central.

If there is no will: spouse and children

The surviving spouse and the deceased's descendants are the first class of statutory heirs.

The inheritance is divided per head between the spouse and children, but the spouse's share cannot be less than one quarter of the estate.

Examples:

• spouse + one child: normally one half each
• spouse + two children: normally one third each
• spouse + three children: normally one quarter each

With a larger number of children, the spouse's statutory minimum of one quarter becomes important.

If there are no children but there are parents or other ascendants

The spouse and ascendants are then called together.

Under Article 2142:

• spouse receives two thirds
• ascendants receive one third

If there are no descendants or ascendants

The surviving spouse is called to the whole intestate estate.

Can a will exclude the spouse?

If Portuguese forced-heirship law applies, not freely.

The spouse is a compulsory heir.

The protected share depends on who else survives.

Spouse alone

If there are no descendants or ascendants, the spouse's reserved share is one half of the estate.

Spouse and children

The spouse and children together have a collective reserved share of two thirds of the estate.

The remaining one third is the freely disposable portion.

Spouse and ascendants

The spouse and ascendants together have a collective reserved share of two thirds.

Again, only the disposable portion can be freely allocated by will.

A will therefore does not normally give unlimited freedom to remove a spouse or child from a Portuguese-law succession.

Intestate share and reserved share are not the same thing

This distinction matters.

The intestate rules answer:

What happens if there is no effective will dealing with the property?

Forced-heirship rules answer:

What minimum part must remain protected even if there is a will?

Do not use an intestate percentage table to calculate a reserved share, or vice versa.

What about a prenuptial waiver of inheritance rights?

Portuguese law contains a specific statutory route allowing spouses in defined separation-of-property arrangements to renounce their status as heirs through the prenuptial framework.

That is a special structure with its own conditions and surviving-spouse protections.

It is not the same as signing a general waiver after marriage.

If such a clause exists, it must be reviewed before calculating the estate.

What happens to the family home?

Inheritance ownership and the right to remain in the family home are separate questions.

Portuguese law gives a surviving spouse specific family-home protections at partition.

A separate rule applies where spouses used the special statutory inheritance-waiver regime.

What if the deceased received an inheritance during the marriage?

An asset inherited by the deceased during marriage may have been separate matrimonial property before death.

That can affect what enters the estate, but not whether the asset is part of the deceased's succession once the deceased owned it at death.

International couples need two applicable-law checks

For an international married couple, determine:

• 1. the law governing the matrimonial property regime;
• 2. the law governing succession.

They can be different.

When legal review makes sense

Review the estate early if:

• the couple has assets in several countries
• one or both spouses have multiple nationalities
• the deceased lived outside Portugal
• there is a foreign will
• there is a prenuptial agreement
• children are from different relationships
• the family home is the main asset
• company shares are part of the estate
• heirs disagree on what belonged to the deceased

Need a clear succession and matrimonial-property analysis?

We can separate the matrimonial estate from the inheritance, identify the applicable-law issues and map the surviving spouse's legal position.
