A user is seeking clarification regarding surety requirements for a death claim following their brother's passing. The nominated father predeceased the brother, making the mother the legal heir. Despite providing a Legal Heirship Certificate and surety from the mother's son-in-law, the branch rejected the surety as it was from a close relative. The user questions why the LHC is insufficient and if surety is mandatory, especially when the son-in-law is not directly involved in the claim.
