I was married for 17 years, remarried at 50 and separated at 60. My second wife and I have not yet divorced. My first wife is older than I and already drawing Social Security. My second wife is much younger than I am. Am I able to file disability on my first wife's income if separated from my second wife? If not, would I be able to if my second wife and I actually divorced? My social security based on me alone will only be about $450, I am also disabled and receiving SSI. I turn 62 in July.
