Recovery of Nationality Lost Through Marriage to a Foreign National (Recuperação da nacionalidade perdida por casamento com estrangeiro)

Blank form for the historical case of a woman who lost Portuguese nationality by marrying a foreign national and wishes to recover it.

What it is for

  • Recovering Portuguese nationality lost as a result of marriage
  • Regularising a long-standing situation created by nationality rules that have since changed
Example (fictitious). Titus Gorila's grandmother, born in Portugal, lost her nationality when she married in the 1960s and now wants to become Portuguese again.

What it is

This is an IRN form for women who lost Portuguese nationality through marriage to a foreign national, a historical situation. It is used to apply for nationality to be restored. It does not apply to people who lost nationality for any other reason, and it does not, by itself, guarantee the decision.

What you receive

You receive the official blank PDF form, with an explanation of what it is for. The Titus assistant answers your questions about filling it in. You can combine it with other documents in the same request, with a single payment. We do not ask for any password for forms.
