Child custody in Guinea-Bissau
Guinea-Bissau follows the Portuguese civil-code tradition, in which both parents exercise parental responsibility and the court decides by the child's interests.

A general outline, not a checked profile
We have not yet researched Guinea-Bissau line by line. This page describes how countries with the same legal tradition usually work, so that the map is not blank, and it can differ from the law in Guinea-Bissau. Reliable, current information is hard to find for many African countries: laws are often not published online or not translated, customary and religious rules are unwritten or differ from one community to the next, and reforms are not always reported.
Can you help? If you know the rule in Guinea-Bissau, or you work with its law, please email us what it says and where it is written. We will check it and update the page, with credit if you wish.
If the parents are married
Both parents exercise parental responsibility together, and the child's interests come first.
If the parents are not married
The parent who recognises the child holds parental responsibility. Where only the mother has recognised the child, she holds it alone until the father does so.
The unmarried father, in one line: Depends on the form of the marriage and on the community.
After a divorce or separation
The court decides where the child lives and the contact of the other parent, by the child's interests. Important decisions stay joint in many countries of the tradition.
What the child can say
The child's views are heard according to age and maturity.
Moving house or moving abroad with the child
Where both parents have parental responsibility, taking a child to live abroad generally needs both parents' agreement or a court's permission. Check the rules before any move.
If the parents live in different countries
Guinea-Bissau is not in force under the 1980 Hague Child Abduction Convention, so there is no treaty route to ask for a child to be returned. Local advice is essential.
What to watch for
- Many families live under customary law, which varies from one community to the next and is often unwritten. In some communities a child belongs to the father's family, in others to the mother's, and the courts increasingly apply the child's best interests whatever the custom says.
Understand the legal system first
Guinea-Bissau belongs to the Civil law family. Family law grows out of the legal tradition, so it helps to know how the system works.
