Is the death certificate, cremation certificate and the signature of the deceased brother useful?
You can't. The immediate family members of the deceased must be present to sign. If the deceased has no immediate family members, collateral relatives shall be present and signed by the police station. Death certificate, cremation certificate, the signature of the deceased brother is useless. Death certificate is the premise and foundation of inheritance: inheritance can only begin after the death of the decedent; Death certificate is one of the indispensable proofs of inheritance notarization.
