I was born Ms A to parents: Mr&Mrs A. Aged 16 I discover (from Birth Cert) I'm in fact Ms B. My mother had an affair & signed the Cert Mrs B, along with Mr B (who died shortly after. She didn't tell me nor did she allow Mr A to adopt me.
I change my name to Ms A-B. Aged 30, I marry & become Mrs C (at this point I also change my Christian name. Born in England, lived in Scotland so went over border to lawyer to do it properly).
I am now Divorced. I'd like to change my name to reflect that. Can I simply use (any of the combinations of) previous legal names or do I need to change it formally ? (still Scotland)
