My ex-husband and I have been divorced 20+ years and I have not remarried. I understand I can claim spousal benefits on his record, but he has to be eligible for benefits. I'll be 65 next year and he'll be 61. My question is, can I apply to receive benefits on his record when he's 62 or do I have to wait until he actually starts receiving benefits himself?
This page discusses benefits for a divorced spouse.
That page says "If you have not applied for retirement benefits, but can qualify for them, your ex-spouse can receive benefits on your record if you have been divorced for at least two continuous years."
So the two important considerations for you are (1) ex-spouse does not need to be actually collecting their SS benefit at the time you collect and (2) if in such case you have been divorced for at least the 2 years they describe...which you meet.
