Macau’s legal history may provide grounds for recognition or attribution of Portuguese nationality. The assessment depends on the date and place of birth, parentage, relatives’ nationality and the documents available.

MNF Advogados assesses these cases with attention to the historical legal framework and each family’s documentary evidence, including where applicants live outside Macau or Portugal.

Who may be eligible

The following periods help identify the applicable framework. They are not application deadlines and do not replace an individual assessment or checks for any specific deadlines.

Up to 20 November 1981

Birth in Macau may provide grounds for recognising Portuguese nationality by origin under the legislation applicable at the time, including Law No. 2098 of 1959. The birth must be proved, legal conditions and exceptions checked, and any later changes of nationality assessed.

From 21 November 1981 to 19 December 1999

When Law No. 37/81 entered into force in Macau, Portuguese nationality held by at least one parent became decisive for nationality by descent. Birth in the territory alone is not enough.

From 20 December 1999

The transfer of administration does not exclude descendants of Portuguese nationals. Children of a Portuguese mother or father may qualify under the rules for those born abroad, through birth registration or a declaration, provided the legal conditions are met.

Descendants born in Hong Kong, mainland China or other countries may also have grounds to apply. The requirements for children differ from those for grandchildren. Marriage, a de facto union or naturalisation are separate routes, subject to their own conditions.

Why family records matter

Identity, parentage and relevant nationality must be established in each generation. Differences in names, Chinese transliterations, dates or spelling may require clarification or correction of records. A Macau resident document alone does not establish Portuguese nationality.

Nationality by origin takes effect from birth, even if registered later. It differs from subsequent acquisition, including through naturalisation. This distinction may change the legal basis available to children.

Documents that may be required

Depending on the circumstances, you may need:

  • The applicant’s identity document;
  • A birth certificate and, where legally relevant, historical parish records;
  • Parents’ or grandparents’ birth records and nationality documents;
  • Marriage, parentage or name-change documents, or evidence linking different names.

This list is indicative. Certification, legalisation, translation and verification of authenticity depend on the document and procedure. A baptism certificate alone does not establish all the requirements; a local record may require additional steps with the Portuguese authorities.

Frequently asked questions

I was born in Macau in 1992. Can I apply?

There may be grounds to apply, particularly through a parent’s Portuguese nationality. 1992 is not a cut-off date, but birth in Macau in that year does not, on its own, confer entitlement.

I was born on or after 20 December 1999. Am I excluded?

No. Depending on your circumstances, you may qualify under the rules for children or grandchildren of Portuguese nationals. A territorial connection to Macau ceased to provide grounds for a new acquisition of Portuguese citizenship.

My father or mother does not yet have a Portuguese record. Where should I start?

Start by assessing that parent and their ancestors. The relative’s nationality may need to be proved and registered first, distinguishing nationality by origin from subsequent acquisition.

Are the requirements the same for grandchildren and children of Portuguese nationals?

No. The route for grandchildren requires, among other conditions, a grandparent who held Portuguese nationality by origin and did not lose it, and compliance with the legal requirements for ties to the Portuguese national community.

Do I need to live in Portugal or speak Portuguese?

Nationality by origin as the child of a Portuguese national generally does not require residence in Portugal or proof of language knowledge. Grandchildren and naturalisation applicants have their own requirements.

Does Chinese nationality prevent an application?

Chinese nationality does not, on its own, prevent attribution under Portuguese law. However, status before the Macau authorities, any applicable choice of nationality and consular protection require a separate assessment. The two legal systems have different rules.

How long does it take and what does it cost?

The time required depends on preparation of the application, checks and the authorities’ processing. We explain costs after assessment. Public fee exemptions do not necessarily eliminate document expenses or professional fees.
