Legal Question in Banking Law in India

how about mother? if mother is not alive, and there is no other legal heir, he surely may do so

if the father is succeeded only by his son and no other heir like mother etc., he can create an equitable mortgage with the title deed in the name of the father and supporting documents like heirship certificate issued by Revenue authorities, change of property tax registry in his name, transfer of Patta or katha in his name.

no, the son has to obtain the succession certificate first and only then he can mortgage the property. no one can pass on a title better than he holds himself.

The legal heirs of the deceased will need transfer of their name in records-of-rights.
