My Grandfather was the owner of residential property in South Delhi. After his demise my father became the owner as per registered will. My father has 2 sisters. The will clearly states that both the sisters will have no right in the property and my father is the absolute owner. The will is registered. My father has got the property mutated in his name. So in MCD the property is in name of my father. We want to reconstruct the property and approached the bank for loan. Bank has checked all the documents and are stating that my father is getting the ownership only through will. They are asking for Relinquishment deed. As per what I have read, this deed is required when there is no will. Moreover the format of deed states that after demise all legal heirs have equal share in property and two of them will release their share in favour of third. I believe that this is wrong as the will clearly states that both sisters have no right in the property. Please advise whether this is compulsory document to be submitted and is asked by all the banks. Thanks
