Requirements towards the candidate-adopters as per the Belgian legislation:
The requirements towards candidate-adopters are common for the three communities.
Married couples (including same-sex couples), couples in registered partnerships (including same-sex couples), cohabiting couples (including same-sex couples) who have been living together for minimum 3 years as of the time of filing an application for adoption, as well as single persons, are permitted to apply to adopt a child.
The minimal age for candidate-adopters with habitual place of residence in Belgium is 25 years. In case of adoptee is a biological child of the adopter or the child of their spouse or cohabiting partner, the minimal age for the candidate-adopters is 18 years. The adopters should be at least 15 years older than the adopted child and at least 10 years older that the adopted child in cases of adoption of a biological child of the adopter or the child of their spouse or cohabiting partner. No maximum age of the prospective adopters or a maximum age difference between the adopters and the children have been determined at the federal level. Despite that, in practice the French community has introduced a requirement for a maximum age difference of 45 years between the adopters and the adopted children.
