Spouse and Children From Previous Relationships: Who Inherits in Portugal?

A second marriage does not push children from an earlier relationship to the back of the inheritance queue.

If Portuguese succession law applies, the surviving spouse and the deceased person's descendants inherit in the same first statutory class.

The first question is therefore:

Whose children are they legally?

Children of the deceased remain descendants

A child of the deceased is a descendant whether the child was born:

• in the current marriage
• in a previous marriage
• outside marriage

Portuguese constitutional law prohibits discrimination against children because they were born outside marriage.

For succession, do not create a hierarchy between "children of the first marriage" and "children of the second marriage".

The legal family relationship to the deceased is what matters.

What about the surviving spouse's children?

A child who is only the surviving spouse's child does not automatically become the deceased's descendant simply because the adults married.

A stepchild therefore needs a separate legal basis to inherit from the stepparent, for example a legally relevant parent-child relationship or a valid testamentary disposition within the available portion.

Do not assume emotional family membership equals statutory descendant status.

If there is no will

Under Portuguese intestate rules, the surviving spouse and the deceased's children inherit together.

The general rule is division per head.

But the surviving spouse's share cannot be less than one quarter of the estate.

Examples:

Spouse + one child

Two heirs.

The estate is normally divided:

• spouse: one half
• child: one half

Spouse + two children

Three heirs.

Normally:

• spouse: one third
• child 1: one third
• child 2: one third

Spouse + three children

Four heirs.

Normally:

• spouse: one quarter
• each child: one quarter

With more children, the statutory one-quarter minimum for the spouse becomes relevant.

Does it matter which relationship the children came from?

Not for their rank as the deceased's children.

If the deceased has:

• one child with a former spouse
• one child with the current spouse

both are children of the deceased and enter as descendants.

The current spouse does not receive a larger statutory class position because one child is from the current marriage.

First separate the surviving spouse's own matrimonial property

The inheritance is not necessarily the couple's entire property.

If the spouses owned common matrimonial assets, the surviving spouse's own matrimonial share is separated first.

The estate then contains:

• the deceased's separate property
• the deceased's share of common property

Only that estate is divided among heirs.

This is especially important in blended families because a child may incorrectly assume that all property registered during the marriage belonged entirely to the deceased, or a spouse may incorrectly assume the opposite.

Can a will leave everything to the new spouse?

If Portuguese forced-heirship law applies and the deceased leaves a spouse and children, not generally.

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

Only the remaining one third is freely disposable.

A will can use the disposable portion to favour:

• the spouse
• one child
• another person
• an organisation

but it cannot simply erase the compulsory heirs' protected share.

Can a will leave everything to the children and exclude the spouse?

The same problem works in the other direction.

Where the spouse is a compulsory heir under Portuguese law, the spouse's protected position must also be respected.

A blended-family will needs to work with the forced-heirship structure, not pretend it does not exist.

Intestate shares and forced-heirship shares are different

Without a will, Article 2139 determines how spouse and children share the intestate estate.

With a will, the forced-heirship rules determine the portion that cannot be freely disposed of.

These are related but not identical calculations.

Do not take the spouse's one-quarter minimum from intestate succession and treat it as the spouse's universal minimum under every will scenario.

What happens to the family home?

The family home can become the practical centre of a blended-family succession.

The surviving spouse may have:

• an existing matrimonial ownership share
• inheritance rights
• specific statutory family-home protection

The deceased's children may simultaneously be co-heirs.

What if the deceased had property before the second marriage?

That asset may have remained the deceased's separate matrimonial property during the marriage.

If the deceased still owned it at death, it can enter the estate.

International families need an applicable-law check first

A Portuguese asset does not necessarily mean Portuguese succession law governs the whole succession.

Under the EU Succession Regulation, habitual residence at death is generally the default connecting factor, and a nationality-based choice of law can be possible.

The matrimonial property regime is a separate applicable-law question.

Common blended-family risks

Assuming stepchildren inherit automatically

They do not become the deceased's descendants merely through the marriage.

Treating the entire family home as inheritance

The surviving spouse may already own a matrimonial share before the estate is calculated.

Writing a will that ignores compulsory heirs

The will may not achieve the intended result if forced-heirship rules apply.

Ignoring assets outside Portugal

Cross-border succession can apply one law to the succession as a whole.

Leaving company shares out of the analysis

Business participations can create corporate-law and succession issues on top of family law.

When legal review makes sense

Review the family structure if:

• either spouse has children from an earlier relationship
• there are stepchildren
• the family home is the main asset
• there is a second or later marriage
• one spouse owned major assets before marriage
• a will is being prepared or challenged
• company shares are involved
• assets are spread across countries
• family members disagree on who owns what
