Yes, in certain circumstances, someone else can submit a life certificate on your behalf. For example, if you are unable to personally visit the issuing authority or provide the necessary documentation due to illness, disability, or other valid reasons, you may appoint a representative to act on your behalf. This representative could be a family member, a trusted friend, or a legal guardian. They would typically need to present the necessary identification and provide any relevant supporting documentation to support their authority to act on your behalf.
