Anyone in banking- mortgage DIP/AIP in maiden name what to do?

[Napqueen1234]

Hello,
Boring question- my mortgage is from 3 years ago and in my maiden name with my husband. We are looking to move so applied via same bank for an AIP- all fine. Went to continue application and realised I now use my married name and will want this for all legal documents/deeds etc. So I just take my marriage certificate to the bank (HSBC) and they can update my details on the account AND the AIP? Or will I have to start the application again?
Thanks!
