I married in 1979, took my husband’s name but the marriage only lasted just over three years. When we divorced I didn’t change my name as I had just had the hassle of changing it three years earlier! I met my current partner nearly 40 years ago and still going strong. We’ve never married and our (then) mortgage was in both our names (my married name).
When I retired a couple of years ago I wrote a book for fun and self-published it on Amazon. I used my “maiden” name as it sounded better. My partner’s daughters thought it sounded good too. So I decided (after nearly 40 years) to change it back by deed poll. It was easy to do, but I still had the hassle of going personally into the bank, building society etc., finding another person to witness my new name, as two organisations wouldn’t accept my partner’s signature as he had signed the deed poll.
I was glad I did - as my married name was meaningless to me. My dear old mum (98) being a bit old fashioned asked me why, if I was changing my name, didn’t I change it to my partner’s name!!! There are always things you forget though - my Tesco vouchers were refused because my “new” name was on the card and the vouchers were in my old name! Their incompetence, not mine.
My friend had a very exotic Ukrainian “maiden” name and when she divorced uses this for informal purposes but has never done it officially. I think it was because she was well know in her profession by her married name. Horses for courses, I say. By the way, when I was a young girl I hated my ‘maiden” name - a traditional Scottish surname - but I love it now.
