Hi Larry,
I have been on social Security disability since 1997. I am 62 and got married 12 years ago and was blessed with a daughter who is now nine years old. I recently found out about auxiliary benefits and contacted SSA and now await monthly payments for her. What I would like to know is will they pay a lump sum retro-active to when she was born in 2013? If not, why?

Thanking you in advance for your help.

Hi. No. One of the requirements for benefit entitlement is filing an application (https://www.ssa.gov/OP_Home/handbook/handbook.03/handbook-0323.html). And, benefits payable to children on the account of a parent who is receiving Social Security disability (SSDI) benefits can only be paid retroactively for up to 12 months prior to the month of the child's application (https://www.ssa.gov/OP_Home/handbook/handbook.15/handbook-1513.html). So, unless an earlier protective filing date was established for your daughter, her back pay would be limited to 12 months prior to the month you applied for benefits on her behalf.

Best, Jerry
