A court in Lleida, Catalonia, has restricted a mother’s right to live in the family home after evidence revealed she was cohabitating with a new partner. The decision was made following a report from a private detective hired by the father, which demonstrated the partner had regular access to the residence using their own keys. The court determined this constituted a stable and ongoing cohabitation, impacting the mother’s claim to the family home. Consequently, the court increased the child support payment owed by the mother for their daughter. The ruling prioritizes the stability of the family home and adjusts financial obligations based on the mother’s changed living situation. This case highlights the legal implications of cohabitation on prior family arrangements and child support orders in Spain.
