If you need to transfer a house registered under your deceased mother's name to your own, you'll likely need to obtain a legal heir certificate from the relevant authority (like the Tehsildar or a court). Once you have this, you can apply to the municipality for the name transfer. It's also important to understand that upon death, property often vests jointly with legal heirs, and the process may involve mutation rather than a formal ownership transfer. Consulting a local lawyer is recommended for specific advice.
