- Regularising a long-standing situation created by nationality rules that have since changed
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.
The assistant explains; it does not fill in or submit anything on your behalf. Do not type passwords or third parties' data.
Things to note
The form comes unfilled; the applicant fills it in and signs it. Please confirm the required documents, such as the marriage certificate, with the registry office. Titus Docs does not send the application and does not ensure that it will be approved.
