Portugal has become a leading destination for individuals and families seeking both quality of life and a clear path to citizenship. As more residents obtain Portuguese nationality through naturalisation, an important question arises: can their children become Portuguese citizens too? For internationally mobile families, citizenship is a shared objective, making it essential to understand how minor children may acquire nationality after a parent naturalises.

Can My Child Become Portuguese If I Naturalise? A Legal Guide for Families

Under Article 6(1) of the Portuguese Nationality Law, Law no. 37/81 of 3 October, residents may apply for Portuguese citizenship once the following requirements are met:

• Be of legal age or emancipated under Portuguese law
• Have been legally resident in Portugal for at least five years
• Have sufficient knowledge of the Portuguese language
• Not have been convicted, by final judgment, to a prison sentence of three years or more for a crime punishable under Portuguese law
• Not pose a danger or threat to national security or defence

For an individual applicant, the legal framework is relatively straightforward. Families, however, often raise an additional question: must minor children  wait until reaching legal age to apply for Portuguese citizenship, or can they benefit from their parent’s naturalisation?
 
It is commonly assumed that once a parent becomes a naturalised Portuguese citizen, nationality may automatically be passed to minor children. That assumption is not entirely accurate.
 
The Portuguese Nationality Law contains a specific provision addressing this situation. Article 2 establishes that minor or legally incapacitated children of a parent who acquires Portuguese nationality may also acquire Portuguese citizenship, by declaration.
 
Article 2 reflects an important principle of nationality law: family unity. When a parent becomes Portuguese, the legal system provides a mechanism to align the status of dependent children.
 
However, acquisition under Article 2 is not automatic and is subject to legal scrutiny.
 
An often overlooked element arises from Article 56(4) of the Portuguese Nationality Regulation, approved by Decree Law no. 237 A/2006 of 14 December. Under this provision, the Public Prosecutor may oppose the acquisition of nationality where no effective connection to the Portuguese community is demonstrated.
 
In practice, such connection is generally evidenced where the child:

• Has legally resided in Portugal for at least five years
• Has attended a Portuguese educational establishment

This requirement frequently raises questions for internationally mobile families.
 
For example, Golden Visa applicants may wonder whether it is sufficient for the main applicant to become a Portuguese citizen, or whether children must also reside or study in Portugal.
 
Due to the specific residency requirements of the Golden Visa regime, children are not expected to reside continuously in Portugal for five years, nor is school attendance in Portugal mandatory. However, it is essential that children hold a valid residence permit as dependent family members.
 
Although it may appear unnecessary at an early stage to submit a residence application for a very young child, maintaining lawful residence status is of fundamental importance to preserve future eligibility under Article 2.
 
Without holding a residence permit for the relevant period, the child’s application may face increased scrutiny regarding the existence of a genuine link to Portugal.
 
In some cases, children born in Portugal to foreign parents may qualify for Portuguese nationality under different provisions of the law, depending on the parents’ residence status at the time of birth. Careful legal analysis is required to determine the most appropriate pathway.
 
Given the ongoing public discussions surrounding nationality law in Portugal, it is essential to rely on the legislation currently in force and on the administrative practice of the Portuguese authorities. Applications should be structured in accordance with the prevailing legal framework rather than anticipated reforms.
 
For internationally mobile families, advance planning and coordinated strategy are key. With proper preparation and specialised legal guidance, the process can be managed efficiently and predictably, ensuring that the entire family progresses together towards a shared legal status.
