Having a baby in Portugal drops you into three separate bureaucracies at once, and which ones actually apply depends on your own status when the baby is born — not a fixed checklist everyone follows the same way. Portugal is a jus sanguinis country by default (citizenship follows the parents’ nationality, not the place of birth), with a narrow exception that puts Portuguese nationality within reach for some expat families, and a separate digital process through AIMA for families who don’t qualify or don’t go that route. Note: Portugal’s nationality law changed significantly on May 19, 2026 — if anything you’ve read elsewhere says a parent only needs one year of residence for their baby to qualify, it’s citing the old rule. See our full breakdown of what changed in the May 2026 reform for the bigger picture; this guide reflects the current law. Here’s the order to actually work through this in.
Step 1: Register the Birth Within 20 Days
This part is the same for everyone. Portuguese law requires the birth to be registered within 20 days, and it’s free. In practice, almost every public hospital and many private maternity units have a Nascer Cidadão desk on-site — a one-stop registration point where you can register the birth (and often request the Citizen Card, if the baby qualifies for one) before you even leave the hospital. If your hospital doesn’t have one, or you miss the window there, you register at any Conservatória do Registo Civil (civil registry office) instead — appointments can usually be booked in advance.
One practical note for foreign parents: Portugal also offers online birth registration, but it requires the registering parent to authenticate with their own Cartão de Cidadão or Chave Móvel Digital — Portuguese digital ID tools you won’t have unless you’re already a Portuguese citizen yourself. For almost every expat family, that means registering in person, either at the hospital or the Conservatória.
Step 2: Find Out If Your Baby Qualifies for Portuguese Nationality
This is the fork that determines everything downstream, and it’s worth getting right before you assume you need AIMA or CRUE at all — especially since this rule changed materially in 2026. Under Portugal’s Nationality Law (Lei n.º 37/81, Article 1(1)(f), as amended by Lei Orgânica n.º 1/2026, in force May 19, 2026), a child born in Portugal to foreign parents qualifies for Portuguese nationality at birth only if:
- At least one parent has held legal residence in Portugal for five years at the time of birth. This replaced a far more permissive test that applied before May 2026 — legal residence on the birth date with no minimum duration, or just one year of physical presence even without formal status. Both of those routes are gone. Five years of documented legal residence for one parent is the bar now, with no shortcut.
Practically, this means a family that arrives in Portugal on a D7, Digital Nomad Visa, or Golden Visa and has a baby in year one, two, or three no longer gets an easy nationality path for that child — the parent simply won’t have five years on the clock yet. That’s a real change from how this worked before 2026, so don’t assume an older article (or someone else’s experience from a few years back) still applies. Full detail on the reform itself, including a grandfather clause for cases already filed before May 18, 2026: what changed in Portugal’s 2026 nationality law.
If your family does clear the five-year bar, nationality still isn’t automatic on its own — a parent has to formally declare it. In practice, this declaration is made at the Conservatória, either when you register the birth or afterward, and if it’s accepted, the baby’s Portuguese birth certificate reflects Portuguese nationality from that point. From there, you can request the baby’s first Citizen Card (Cartão de Cidadão) — free for children under one — and apply for a Portuguese passport.
Step 3 (Non-EU Parents): The AIMA Residence Permit Route
If nationality doesn’t apply — or your family simply prefers to keep the baby on your own citizenship for now and get them a standard residence permit instead — and you’re a non-EU/third-country national parent who already holds a valid Portuguese residence permit yourself, the baby needs their own residence permit under Article 124 of the Foreigners Law, processed by AIMA (the agency that replaced SEF in 2023).
As of 2026, AIMA runs this specifically through a new digital scheduling tool rather than the general appointment queue — a real, recent improvement worth knowing about if your information is a year or two out of date. The process:
- Log into AIMA’s online portal at contactenos.aima.gov.pt
- Select the Residence Permit category, then the specific option for scheduling appointments for minors born in Portugal
- Enter the baby’s details and upload the required documents
- Attend the scheduled appointment with the originals
Documents typically requested: the baby’s Portuguese birth certificate, the resident parent’s passport and valid residence title, and the other parent’s residence or identity document if applicable. Each child needs their own, separate application — a second baby a few years later means doing this again from scratch.
The deadline is strict and unforgiving: six months from the date the birth was registered, not from the birth itself. Applications submitted after that window, or missing required documents, are automatically rejected — there’s no stated grace period, so don’t let this slide to the bottom of the to-do list once the registration step is done.
Step 3 (EU/EEA/Swiss Parents): CRUE Instead of AIMA
If a parent is an EU, EEA, or Swiss citizen exercising free movement rights in Portugal — including a Latin American family that secured Italian, Spanish, or Portuguese citizenship by descent and relocated under that passport — AIMA generally isn’t the right agency at all. EU citizens and their family members register residence through a lighter, separate track: the Certificado de Registo de Cidadão da União Europeia (CRUE), filed at the Câmara Municipal (town hall) of your area of residence, not through AIMA.
A baby born to an EU-citizen parent typically holds that parent’s nationality by descent — which means before CRUE even comes into play, you need to get the baby their own passport (or have them added to a parent’s passport) from that country’s consulate in Portugal, since a CRUE certificate is a residence registration, not a travel document.
Once that’s sorted, the CRUE process itself:
- Required once you’ve been in Portugal more than three months; you have 30 days after that three-month mark to apply
- Filed at the Câmara Municipal covering your residential address
- Fee is modest — commonly cited around €7.50 for young children (some sources note an exemption under age one), against €15 for an adult; confirm the current figure with your specific Câmara, since practice varies by municipality
- Typical issuance takes around a month once filed
The Rest of the Checklist, Regardless of Path
A few more things apply no matter which route your baby’s status takes:
- NIF (tax number): get the baby their own Portuguese tax number — you’ll need it for a surprising number of things later (opening a bank account in their name, school enrollment, health system paperwork). Request it at a Finanças office or through a representative.
- Número de Utente (SNS health number): babies born to legal residents are generally enrolled in the public health system and assigned a family doctor automatically through the hospital at birth. If that doesn’t happen automatically in your case, register at your local Centro de Saúde with proof of residence and the baby’s documents.
- Your own country’s consulate: Portugal registering the birth doesn’t automatically notify your home country. If you want the baby to also hold your own citizenship — common for American, Canadian, British, and most other expat families, and usually the actual goal alongside whatever Portuguese status applies — you generally have to proactively register the birth abroad with your own country’s consulate (for US citizens, this is the Consular Report of Birth Abroad). Don’t assume it happens on its own.
Frequently Asked Questions
Does my baby automatically get Portuguese citizenship just from being born in Portugal?
No. Portugal follows jus sanguinis (citizenship by descent), not birthright citizenship by location alone. As of the May 2026 reform, your baby qualifies for Portuguese nationality only if at least one parent has held legal residence in Portugal for five full years at the time of birth — and even then, a parent has to formally declare it; it isn’t automatic without that step.
I’m on a D7 or Digital Nomad Visa. Will my baby automatically qualify for Portuguese nationality?
Only if that visa/residence permit has already been in place for five years by the date of birth — as of the May 2026 reform, simply holding valid status on the birth date is no longer enough on its own. If you’re earlier in your residency than that, your baby won’t qualify for Portuguese nationality by birth yet; you’d go through the AIMA residence-permit route below instead.
What if I don’t want my baby to have Portuguese nationality yet?
That’s a real, common choice — some families prefer to keep a single citizenship for the child for now, or their timeline doesn’t line up with the declaration process. In that case, if you’re a non-EU parent with your own valid residence permit, the AIMA Article 124 route gives the baby their own Portuguese residence permit instead, on the same 6-month deadline described above.
Do I go to AIMA or the Câmara Municipal for my baby’s paperwork?
It depends on your own nationality. Non-EU parents go through AIMA. EU/EEA/Swiss parents — including Latin American families who hold European citizenship by descent — go through the Câmara Municipal for a CRUE instead; AIMA doesn’t handle EU citizens.
What happens if I miss the 6-month AIMA deadline?
The application is automatically rejected, with no stated exception. If you’re going the AIMA route rather than nationality, treat the 6-month window as a hard deadline from the day the birth is registered, not the day the baby is born.
