This discussion addresses the legalities of gifting a residential flat in Mumbai, particularly to non-family members. It clarifies that such gifts are valid if a properly executed and registered gift deed is used, governed by the Transfer of Property Act, 1882. Key points covered include the necessity of registration, stamp duty (5% for non-relatives in Maharashtra), and tax implications where gifts exceeding ₹50,000 in stamp duty value are taxable for the recipient. The thread also delves into rectifying an invalid, unregistered transfer of a flat from 1989, suggesting legal recourse via a declaration suit or a complaint under Section 79 of the Maharashtra Co-operative Societies Act if the society fails to act.
