A relative of mine is a widow whose husband died about 15 years ago. She remarried before she turned 60, so she is not eligible to the survivor benefit from her late husband. She has been married less than 10 years. She is now 63. My understanding is if she and her current husband divorce, she would become eligible for his survivor benefit, which is 50% higher than her current full retirement amount. Is my understanding correct? Also, if it is correct, is there any waiting period after a divorce before she would be eligible for the survivor benefit?
