This discussion addresses the need to update an Index-2 document to reflect current ownership, particularly when a property was initially registered under a father's name. The individual in question has been managing the property and paying bills for years, with siblings relinquishing their claims via a family deed. The advice given is that a registered release deed from all legal heirs is mandatory to establish sole ownership for redevelopment purposes, as a notarised deed is insufficient. This registered deed will formalise the transfer and ensure the Index-2 is updated correctly.
