There are certain stipulations to collect on a former spouse’s SS. If at the time of eligibility she is unmarried, then yes, but it will not affect the amount of SS benefits that you are eligible to receive. If she has paid more into the system than you have then it wouldn’t benefit her to claim under your SS. Again, whatever she does this should not interfere with the amount that you are due to receive in your golden years.
