My granddaughter, who is 16, has always used my surname and originally this was the name on her birth certificate. However her mother had the name on the birth certificate changed to that of her partner when they got married, even though he’s not her father. Now my granddaughter wants to open a bank account, and they’re insisting on seeing her birth certificate. But she doesn’t want to open an account in that name.
The General Register Office in Southport has a department which will correct errors, and when she’s older your granddaughter may be able to get hold of her original birth certificate. In the meantime she should be able to open a bank account with other documentation – perhaps a letter from the school – showing that she uses a different name. Ask the bank what proof it requires.
