There have been several instances in the high court and most recently in the Supreme Court of India where the court permitted the mutation of property records in the name of the legal heirs, but clearly stated that this does not mean ownership gets transferred to the legal heirs.
In simple terms, mutation records show who is responsible for paying property tax and other administrative work related to the property. Ownership of a property can be proved by sale deed, or Will, or Settlement deed or family arrangement deed or other legal documents.
