My understanding from my lawyer is that the legal name change doesn't go through until after the divorce is final...but maybe I misunderstood. For me after 33 years with my married name & my degree is under my married name I decided to not bother changing it. New job & having people now know you by your maiden name is good....why your mother would address you ain't that formal way in the first place is beyond me?...it's not important for family to call someone by their legal name in the first place....sounds like your mom just holds onto some weird thoughts & won't let them go....some people are just like that & it's just what they are like...like it or not.....it's not critical, just annoying
