I have a property which is In my grand fathers name, now the question is neither my grand father nor my father is alive. What should be the procedure to transfer the property to my name where I can avail loan from banks.
The property that belonged to your grandfather, if has not been disposed by him in any manner known to law, then upon his intestate death shall devolve equally on all his legal heirs, which includes, his wife, children and mother. This will include your father too.
Therefore, if your grandmother is not alive, then this property shall devolve on all the legal heirs of your father and his siblings and the legal heirs of the deceased siblings.
You should ascertain this and get the consent of everyone entitled to a share in the property to express their no objection to transfer this property on your name and your mother and your own siblings too have to express their no objection.
The most important is that everyone have to execute a registered release deed in your favor to make you the absolute owner to the property.
