I have decided I want to use my maiden name at work which led to what I find was a bizarre conversation with my professional body. since we're referring to law, I'm in Scotland btw.
First I was told it was illegal for a married woman to use her maiden name and I would have to be divorced and then use my divorce papers to be granted a deed poll to change my name or I'd be breaking the law. She then said I had to change my passport. When I explained I didn't have a passport she claimed it was illegal not to have one for which I had to explain not if I didn't attempt to travel abroad.
After 10min of going round in circles with the above conversation she agreed I should send my birth certificate and get statements from colleagues to confirm they are happy for me to be know by my maiden name (eh?). So I said "right so birth certificate, marriage certificate and statements?" She said "no just your birth cert" and when I asked "surely it's my marriage certificate that links the 2 names" and she said no. worryingly she said they only accept England and wales birth certificates and I was born in Scotland so not sure if that means I don't exist
Your colleague was spouting a load of rubbish, if you wish to change your name the only repeat the only way to do so is to start using your “new” name. Nobody has to approve or confirm they are happy for you to be known by your new name (or maiden name) it is your choice and your right.
Devices like deed poll only prove that a change of name has occurred they do not change your name.
Passports, if you have a passport in your old name you can legally use your passport until it expires (there is no legal requirement to change it before) however if you book airline tickets the have to be booked in the name of the person on the passport.
Banks these days will ask for proof of a name change just show them your decree absolute and your marriage certificate
There is one document you do have to change immediately and that is your driving licence. It costs nothing to do so (use form D1) as you can be fined up to £100 if you fail to notify the DVLA of a name change.
