A user is facing an issue where their deceased father's property deed is registered under one surname (Y), while his death certificate and family's surname is another (X). This mismatch is causing problems in transferring the property to the mother as the legal heir. The advice suggests proving both surnames refer to the same person, potentially through a notarised affidavit by all legal heirs and publication in a newspaper. Consulting the local Registrar and a legal advocate is recommended to explore options like rectification deeds or 'one and the same person' certificates, rather than immediately resorting to court action.
