DEATH WHILE A CLAIM IS PENDING Written by WebAdmin on June 18, 2019. Posted in Uncategorized Tragically, the Social Security adjudication system is so disorganized and slow that our clients may die before a claim is made on their case. In cases of Supplemental Security Income and Social Security Disability, surviving family members may be able to receive back benefits. This may be surviving children, spouse, or parents.To do so, they must file as a substitute party. See https://www.ssa.gov/OP_Home/hallex/I-02/I-2-1-50.html. An experienced Social Security Attorney can help with this process.
