Cohabiting couple

A cohabiting couple is defined as two spouseless adults of different sex aged 18 and over and occupying the same dwelling on a permanent basis, provided their age difference is less than 16 years and they are not siblings. In case the couple has a common child these specifications do not apply. Same-sex persons living together are not considered cohabiting couples unless they have a common child in the family. As a rule, these are female couples in which one woman is the biological mother of the common child and the other is the second mother established for the child (Parenthood Act 775/2022, Section 5).
