A minor is eligible for Portuguese citizenship if at least one parent is a Portuguese citizen, by birth or naturalization. Nationality is acquired by declaration, not automatically, and becomes legally effective only after registration with the Portuguese Civil Registry. The process differs depending on whether the child was born before or after the parent became Portuguese.
Minors are never required to submit a criminal record certificate.
Portuguese citizenship for minors is one of the most secure and legally protected nationality pathways under Portuguese law. Children of Portuguese citizens have a legal right to Portuguese nationality, provided the correct civil registrations and declarations are completed. This guide explains eligibility, procedures, documents, fees, and timelines, in accordance with the Portuguese Nationality Law (Lei da Nacionalidade — Law No. 37/81) and current civil registry practice.
A minor may be eligible if at least one parent is a Portuguese citizen, either by birth or by naturalization.

While not legally mandatory, registering the parents' marriage in Portugal before applying is strongly recommended — it helps prevent delays and requests for additional documentation.
Minors born before a parent's naturalization may still acquire Portuguese citizenship by declaration, provided the legal and civil requirements are met.
If the parents are married, marriage transcription in Portugal is required before the child's nationality application. Applications submitted without this step are commonly suspended or rejected.
Consent from both parents is required. If one parent is absent, deceased, or unavailable, additional legal documentation or a court decision may be required.
All foreign documents must be apostilled and, when required, translated into Portuguese.
No. Minors are not required to submit a criminal record certificate. This requirement applies only to adult applicants under specific nationality routes.
