Divorced, name change

Hello
I applied for student finance and sent off the evidence needed from myself and my mum.

My mum sent a decree absolute which proves she is now divorced. We have received a letter today saying that on the application her name is her birth name and on her decree absolute it is her married name. You have asked for proof that every is using another name.
She has returned to her birth name following her divorce. Do I still need to send evidence as she hasn’t completely changed her name she has just gone back to her birth name following the divorce?

Thank you
Charley
