Key legal question
Whether a privately signed maintenance agreement between an adult child and the father is enforceable without court or guardianship approval for advance maintenance purposes.
Extracted holding
A maintenance agreement between parents and an adult child is sufficient if the parties agree and sign it; it does not require judicial or guardianship approval to be enforceable.
Extracted reasoning
Art. 287 ZGB on approval of child maintenance agreements applies to minor children. For a competent adult child, the agreement may be concluded in simple written form, and no material review by an authority is necessary.
