This discussion clarifies whether an ex-wife can claim maintenance for an adult daughter using a Power of Attorney. While an adult daughter generally cannot claim maintenance under Section 125 CrPC unless she has a physical or mental disability, she may be able to claim it under Section 20 of the Hindu Adoption Act if she proves she is unable to maintain herself. The mother can contest the case on behalf of the daughter with a Power of Attorney, though the POA has limitations in pleading personal knowledge.
