My first husband passed away in 1994 when I was 33. I am now 55 and have been on disability for 3 years even though I'm remarried can I collect on my first husband's benefits

Hi,

No, unless you remarried after age 50 and after you became disabled (https://www.ssa.gov/OP_Home/handbook/handbook.04/handbook-0406.html).

Best, Jerry
