Does my ex-husband have to have filed for his own social security benefits before I can file for spousal only benefits? Or am I out of luck if he hasn't filed yet? I will be 66 this November. He just turned 67 but I think that he is still working (don't know for sure). We were married over 10 years and were divorced 30 years ago. I have never remarried. So I think I am grandfathered in on all the other criteria to file for spousal benefits only this year and wait until I am 70 and then file on my own benefits.
