If a freehold DDA flat owner has passed away, the legal heir needs to complete several steps to transfer ownership. After obtaining a Surviving Member Certificate and applying for mutation with the MCD, further actions are required. These include submitting an affidavit, a relinquishment deed, an undertaking, and an indemnity bond. Additionally, the heir must provide the death certificate, proof of relationship, and potentially an NOC or bank guarantee. Finally, ownership transfer with the electricity department and other utility providers should be completed.
