Form HA-539. Notice Regarding Substitution of Party Upon Death of Claimant

Form HA-539 - Notice Regarding Substitution of Party Upon Death of Claimant is used to notify the Social Security Administration about the substitution of a party following the death of a claimant. The main purpose is to inform the agency of the change in claimant status due to the claimant's death.

For example, if a Social Security claimant passes away, this form would be used to notify the agency of the death and to designate a substitute party who will continue to pursue the claim or benefits on behalf of the deceased claimant. The form's purpose is to ensure a smooth transition of the claim process after the claimant's passing.

The parties involved include the party substituting for the deceased claimant and the Social Security Administration. The form consists of sections for information about the deceased claimant, the substitute party, and a statement confirming the substitution. It is important to promptly notify the agency of the claimant's death and provide accurate information about the substitute party.
