Student finance evidence query

Hello,

I have applied for 21/22 year finance however I have a query with the evidence I need to supply regarding my child.

I have changed my name by deed poll in 2020 and I need to update this with SFE. My question is, will you accept evidence letters in my old name?

For context, my surname was McCarthy but now changed to Charlton. I have a child benefit letter, but this is addressed to McCarthy. My deed poll clearly shows my before and after name. Wondering if this would still be accepted?

Thanks

Claire
