Succession certificate

Dear Concern,

Please advise whether single succession certificate is sufficient for multiple accounts in one bank at diffrent states.

e.g : A, person dies having saving & ppf account in BCD bank at E,F & G states. H, Spouse the nominated one also dies leaving legal heirs behind. No dispute is there.

Please suggest whether one succession is OK or one has to go for three as per juridiction.

Regards
