Do unmarried partners qualify as dependents for the Portugal D8?

Updated 2026-11-12 · Family guide · Not legal advice

Yes, if you're in a de facto union: under Portuguese law (Law 7/2001) that means two people living together as a couple for more than two years. For a D8 family application or reunification you prove it with documents showing a shared home over that period, such as joint leases, utility bills, bank accounts, or a domestic-partnership registration.

Evidence	Strength
Domestic partnership registration	Strong (apostilled)

Joint bank account / tax returns	Good
Photos, travel	Supporting only

Less than two years together?

Your partner can't join as a de facto partner yet. Options are marrying, or your partner applying on their own visa if they qualify.
