Why is there even a discussion about SS. If she is was working then and is working now she is self sufficient.
How long was the marriage? How old is she?
What has been presented by them to indicate entitlement to SS?
Just because her lawyer says something does not mean it is true or you have to take it.
Her lawyer is working to get the best for her, which is his job to do. Top that off with the fact that lawyer have no reason to be honest on how they get that done. No obligation to you to be fare and just with the process, nor what they request.
