Succession certificate

you have to require a succession certificate issued by a competant court.

In govt depts they require the succession certificate for a meger amnount in order to safeguard themselves. get death certiticate and apply legal heirship certiticate there after apply succession certiticate along with the letter issued by department in this aspect. it may take three months in maximum 

Sir, will this succession certificate be valid for her other bank acounts also, because currently i will be applying succession certi for claiming the reimbursement of medical bills ??

for issue of succession certificate you may have to give notice to all the succesors (your brothers, maternal cousines and aunts and uncles) if any one is dead then to his /her major chilren and minor children directly.  In indian society none goes for the real cause, all one knows that filing unproved suit agianst married sister/cousine/aunt is considred to be sin and conduct is seen more damnageble if any one of them is widow. Even those relatives who are not party to this suit will also be happy to severe relations with you and even stop inviting you on family functions. Even th4 authnticity of WILL will be challaned andallegation of forgary will be disturbing for you. You carry on if the stake involved is worth it.  You will be very lucky if the family helps you amicably by simply not responding to such notice. Move only if either their is family amicability or you are thick skinned to bear all humiliation. Chances are their that atleast one greedy among the family can take PAO from all disinaerested parties and make your remaining life miserable. If bank accounts are either nominated or covered by will you may not need succession certificate.
