Paternity Testing and Paternity Disputes in Brazil

Paternity proceedings in Brazil may seek to establish, challenge or clarify a legal parental relationship. DNA evidence can be relevant, but the legal analysis may also consider civil registration and the history of the family relationship.

When legal advice may be useful

  • a parent or child seeks legal recognition of paternity;
  • registered paternity is being challenged;
  • a party lives abroad and testing or service must be coordinated;
  • the result may affect support, civil records or succession.

Issues normally reviewed

The appropriate claim depends on the existing civil record, the factual relationship, available evidence, the persons entitled to act and the legal effects sought.

  • birth certificate and identification documents;
  • communications and evidence about the family relationship;
  • DNA testing arrangements and chain of custody;
  • effects on support, name, nationality and inheritance.

Documents and case preparation

Documents vary according to the matter. An initial review may require identity and civil-status certificates, Brazilian or foreign court orders, property records, financial information, communications and certified translations.

Related Brazilian family-law matters

This issue may need to be coordinated with other Brazilian family-law services, particularly when one case combines children, maintenance, property, civil records or international proceedings.
