I am a 100% disabled vet and I receive social security disability. My 25 y/o daughter is disabled due to a mental diagnosis and cannot work efficiently, so she moved back to my home. I’m thinking of having her file social security disability under my earnings. Is it legal for me to file for helpless child benefits with VA at the same time, since she cannot work?
Yes, of course it's legal. You can file anything you want and the worst that could happen is a firm "No!" I can't offer any opinions on whether or not you will prevail, I just don't know enough and these are complex claims.
But there is no reason not to try. Good luck.
