Not sure how that works out when her actual benefit is less that the spousal, but...
Miss Kitty and I are both over 65 and still working. She is collecting an amount equal to half my current benefit as a "spousal benefit." This will continue until she actually files for her benefits, which are greater than half mine. The "spousal benefit" was meant to provide income for divorced women who had supported the husbands for 10 years or more.
Oh btw, if a woman has had another husband, an ex, with whom she was married to for at least 10 years, she can also collect half of his. Double dip, so to speak. Permission not required, but he must have filed for SS.
None of this in anyway reduces the husband's benefits. Nor does the husband, or ex, even have to know it's happening. I did have the "file and delay" my benefits, but it was just a paper work technicality.
Yes, this is too good to be true. It's being phased out, but you will probably qualify still.
