Two brothers jointly purchased a flat in Mumbai, with the home loan and property ownership legally registered under one brother's name (A). They had an MOU stating a 50% share for the second brother (B), who also agreed to pay half the EMIs. Although brother A is the legal owner, the validity of the MOU and brother B's claim to his share, especially if brother A tries to sell the flat without consent, depends heavily on the specific terms of the MOU and any registered documents. Legal advice is recommended to understand the available remedies and potential disputes.
