A family-reunification application can be legally straightforward and still fail operationally because the documents do not prove what AIMA needs to see.
Three areas cause a large share of the practical work:
family documents, means of subsistence and accommodation.
This guide explains how to prepare those three parts of the file.
Start with the exact family category
Before collecting documents, identify whether the person joining you is:
- spouse;
- unmarried partner;
- minor child;
- adult dependent child;
- adopted child;
- dependent parent;
- minor sibling under guardianship;
- another category recognised for the sponsor's specific residence status.
The category determines the evidence.
There is no universal "family certificate" that proves every case.
Marriage documents
For a spouse, AIMA currently asks for an authenticated marriage certificate.
If the certificate is foreign, check:
- whether apostille or another form of authentication applies;
- whether a translation is required;
- whether the document contains the correct names and dates;
- whether previous marriages create civil-status issues.
Do this before filing.
A translation cannot repair an incorrect source document.
Birth certificates
Birth certificates are commonly used for:
- children;
- parents;
- proof of parentage;
- some dependency chains.
For a parent case, the civil record proves the family relationship.
It does not prove dependency.
For a child case, the birth record may also need to be combined with parental-consent or custody evidence.
Unmarried-partner evidence
For an ordinary family-reunification case, AIMA currently refers to evidence of more than two years of união de facto.
Do not rely on one informal statement if the couple has better objective evidence available.
The file should make the duration and reality of the shared relationship understandable.
Dependency evidence
Dependency matters especially for:
- parents;
- certain adult children;
- some EU-family categories.
Possible evidence can include recurring financial support and records that explain why the family member relies on the sponsor.
The purpose is to show a real dependent relationship, not just occasional transfers.
Criminal records
For a family member outside Portugal, AIMA currently asks for a criminal-record certificate from the person's country of nationality or from the country where the person lived for more than one year before residence in Portugal, subject to the applicable rules.
The certificate must be properly authenticated.
Criminal-record planning becomes more important where the family member:
- has several nationalities;
- lived in several countries;
- has an old conviction;
- has documents issued under different names.
Do not leave this to the end of the file.
2026 family-reunification income calculation
Portugal uses the minimum monthly remuneration as the reference for means of subsistence.
The 2026 minimum monthly remuneration is €920.
For family reunification, the current percentage scale is:
| Household member | Percentage | 2026 monthly reference |
|---|---|---|
| First adult | 100% | €920 |
| Each additional adult | 50% | €460 |
| Each child or dependent adult child | 30% | €276 |
Example: resident + spouse
€920 + €460 = €1,380 per month
Resident + spouse + one child
€920 + €460 + €276 = €1,656 per month
Resident + spouse + two children
€920 + €460 + €276 + €276 = €1,932 per month
These figures are the calculation reference.
The file still needs evidence showing that the household actually has the means relied upon.
A note about AIMA's published example
AIMA's general means-of-subsistence page still displays the 2025 minimum-wage example of €870.
For a 2026 application, the current Portuguese minimum wage is €920, so the percentage calculation should use the current reference.
This is exactly the kind of figure that should be checked again immediately before filing.

Review my family reunification fileWhat can prove means of subsistence?
The answer depends on how the resident supports the household.
Evidence may include:
- employment income;
- independent professional income;
- pension;
- investment or property income;
- bank evidence;
- other lawful resources recognised for the case.
The documents should make clear:
- whose income it is;
- how much is received;
- how regularly it is received;
- whether it is available to the household.
Do not submit a number without the evidence that explains it.
Accommodation
For a family member outside Portugal, AIMA currently asks the resident to declare the address and explain the legal basis on which they occupy the property.
This can include:
- ownership;
- usufruct;
- tenancy;
- subtenancy;
- loan for use;
- another lawful arrangement.
If you own the property
AIMA can ask for property-registry evidence or the relevant access code.
If you rent
A landlord or accommodation-provider declaration may be required to confirm the legal basis on which you occupy the property.
If someone lets you stay there
Do not assume an informal statement is enough.
The accommodation should have a clear legal explanation that matches the address used throughout the file.
Does the home need a specific size?
The current AIMA family-reunification guidance focuses on proof of the residence address and the legal basis of occupation.
That does not mean every accommodation question is irrelevant, but there is no reason to invent a universal square-metre rule that AIMA does not publish for this procedure.
If unusual housing facts may create a problem, review them before filing.
Foreign documents: apostille, legalisation and translation
Authentication depends on:
- the issuing country;
- the type of document;
- the international rules that apply;
- the authority that will receive it.
AIMA also requires foreign-language documents to be accompanied by an appropriate translation.
Do not order apostilles and translations blindly.
First identify:
1. the exact document;
2. the issuing country;
3. the family category;
4. the receiving procedure;
5. the correct authentication route.
Common file problems
Old or incomplete civil certificate
The document does not contain enough information to prove the relationship.
Correct relationship, wrong authentication
The document exists but cannot yet be accepted for use in Portugal.
Correct income calculation, weak evidence
The arithmetic works but the bank and employment records do not explain the claimed resources.
Address used inconsistently
The lease, declaration and application show different addresses.
Parent case without dependency
The birth certificate proves parentage but nothing proves that the parent relies on the sponsor.
Child case without parental-authority evidence
The child qualifies by relationship, but the move itself is not properly authorised.
A practical file check
Before the AIMA stage, confirm:
- [ ] the correct family category;
- [ ] the correct outside-Portugal or inside-Portugal procedure;
- [ ] passports are current;
- [ ] civil documents prove the relationship;
- [ ] dependency is documented where required;
- [ ] parental consent or custody is covered;
- [ ] criminal records are correctly sourced;
- [ ] foreign documents are properly authenticated;
- [ ] translations are ready where needed;
- [ ] the 2026 household income calculation is correct;
- [ ] income evidence supports the calculation;
- [ ] the address and legal basis of occupation are documented.
