Charlene, I'm pretty sure I could get that changed without paying a fee to amend it. I've had to grapple with more than one institution on this point - fair do's if I've made a mistake, but I've found some people place invisible barriers to amending their assumptions in the first place.
When DH and I got married, we both kept our names.
And when Ineeded an account to pay wedding cheques into (I basically just opened an account in the name of Ms MarriedName as well as wanting to keep my normal maiden/married name of Ms MaidenName)... the bank teller tried to say it was illegal. "Oh?" I asked. "Do you mean against bank policy, to have 2 accounts in different names?" ... "No", he said, a concerned look on his face, "it's illegal to do that, it's to do with money laundering."
I then had to explain to him that a woman is under no legal obligation to change her name on marriage, I required the two accounts for logical reasons which I'd explained, and it wasn't illegal. nor was it against the bank's policy as far as I was aware, since my sister had recently done the exact same thing in the exact same home branch of natwest as I wanted to do.
I then had to speak to the manager, a woman who was perfectly polite and sorted it for me no problem. She agreed to educate her bank teller on what and wasn't "illegal", and what the bank's official policy on account names was.
I still remember that little incident, and his look of concer as if I was trying to do something dodgey! And that was about 13 or 14 years ago now!
