Using a Foreign Will in Portugal: What Heirs Need to Do

A person has died, the family has a will made outside Portugal, and there are Portuguese assets or a Portuguese succession procedure.

The key point is this:

there is no single universal Portuguese step called "recognise the foreign will" that solves every case.

The will has to be placed into the correct succession framework, supported by the right evidence and then used for the specific Portuguese assets or procedures that follow.

A practical file normally separates five questions:

  • 1. Which succession law governs the estate?
  • 2. Is the will formally and evidentially usable for this case?
  • 3. What document preparation is required in Portugal?
  • 4. How are the heirs or beneficiaries formally established?
  • 5. How are the resulting rights implemented against Portuguese property, bank accounts or company interests?

Step 1: do not confuse the place of the will with the law governing succession

A will being signed in one country does not automatically mean that country's law governs the entire succession.

For cross-border estates within the EU Succession Regulation framework, the governing-law analysis can depend on matters such as the deceased person's habitual residence and any valid choice of nationality law.

That is a planning and applicable-law question already covered in depth by International Wills in Portugal: Which Succession Law Can You Choose?.

After death, the immediate task is to apply that framework to the actual estate and actual will.

Step 2: obtain the correct will evidence

The family should preserve the complete instrument and determine what type of document it is.

Questions can include:

  • Is it the original instrument, an official copy or only a scan?
  • Was it executed before a notary or other public authority?
  • Is it a private will?
  • Is there a probate or succession certificate from the country of origin?
  • Has any court already dealt with its validity or effect?
  • Is there also a will registered in Portugal?

Portugal has a central system through which the existence of a Portuguese-registered will can be checked after death.

But a negative Portuguese will search does not prove that the deceased never made a will abroad.

Step 3: separate formal validity from substantive effect

Two different questions are often mixed together.

Formal validity

Was the will made in a form recognised by the applicable cross-border rules?

Substantive succession effect

What can the will legally do under the law governing the succession?

A document can be formally valid without giving the beneficiary everything they expected under the applicable succession law.

For example, where Portuguese succession law governs, compulsory-heir rules can affect how much of the estate may be disposed of freely.

This is why the correct analysis starts with the succession framework, not with the document stamp alone.

Step 4: prepare the foreign document for Portuguese use

The Portuguese institution receiving the document may need an official version that it can legally rely on.

Depending on the country and document type, the file can involve:

  • original or certified copy;
  • certified translation into Portuguese;
  • an apostille;
  • another legalisation route;
  • an EU rule that removes a formality for a particular document;
  • accompanying succession certificates;
  • proof of foreign law.

There is no safe rule that every foreign will always needs an apostille.

There is also no safe rule that every will from an EU country can simply be filed without any further document work.

The route has to be checked for the actual document and actual Portuguese authority.

See Foreign Documents for Use in Portugal and Certified Translations.

Step 5: establish the heirs for the Portuguese file

Portuguese banks and registries generally need more than the will itself.

The file may also have to prove:

  • the death;
  • the family relationships;
  • who the heirs are;
  • who is authorised to represent the estate;
  • how the foreign will fits into those rights.

This is where Habilitação de Herdeiros in Portugal can become central.

For some participating EU cross-border estates, a European Certificate of Succession can also help prove the status or powers of an heir, legatee, executor or administrator in another participating state.

It is optional. It is not a universal replacement for Portuguese habilitação or for the will itself.

Step 6: use the succession file against the actual Portuguese asset

Once the succession basis is clear, the implementation still depends on the asset.

Portuguese bank account

The bank will want the succession authority and its own required evidence before it releases information or funds.

Portuguese property

The heirs may need the succession evidence for land-registry and later partition, transfer or sale work.

Portuguese company interest

The will and succession documents may identify the successors, but company-law rules and the company's articles can separately affect what happens to a quota or shareholding. See What Happens to Portuguese Company Shares and Quotas When a Shareholder Dies?.

Unknown Portuguese assets

If the family does not yet know what the deceased owned, the first operational step may be Foreign Deceased With Assets in Portugal: How Heirs Find Property, Bank Accounts and Other Assets.

What if the will and the family expectations do not match?

This is common in cross-border estates.

Examples include:

  • the will appears to leave everything to one person, but compulsory-heir rules may apply;
  • the will was made before a later marriage or divorce;
  • a beneficiary named in the will has died;
  • the deceased had several nationalities;
  • the deceased moved countries after making the will;
  • Portuguese assets are held jointly with a spouse;
  • a Portuguese company has articles affecting transfer on death;
  • the family is unsure whether to accept the inheritance.

The correct response is not to force the will into the expected answer. It is to map the succession law, the estate composition and the document chain together.

If acceptance or renunciation is still open, see Accepting or Renouncing an Inheritance in Portugal.

If the surviving spouse's rights are part of the issue, see Surviving Spouse Inheritance Rights in Portugal.

A practical foreign-will file

Before presenting the will in Portugal, build a file containing the answers to these questions:

QuestionWhy it matters
Where was the deceased habitually resident?Helps determine the succession framework
Did the deceased choose a nationality law?Can change the governing succession law
What exactly is the will document?Determines evidentiary/document route
Is there Portuguese will evidence too?Avoids incomplete testamentary picture
Who are the heirs/beneficiaries?Needed for Portuguese authority file
Which Portuguese assets exist?Determines the implementation route
Are translations or formalities required?Prevents rejection by the receiving institution
Is a European Certificate useful?May simplify cross-border proof in participating EU cases

Need the foreign will prepared for Portuguese use?

THE-Ö can review the document route, coordinate translation/legalisation requirements where they actually apply and prepare foreign succession documents for Portuguese procedures. Where the legal effect of the will or the applicable succession law is uncertain, we can also provide a written legal analysis.
