legal last name?

[Saught]

I am trying to fill out the divorce papers and looking at the marriage certificate and I can not tell what her "legal" name is. Is it still her last name or mine? She did not get a social security number due to an error so she had no name change there nor have a number, that I know of (she been gone for over a year to where, I don't know) so I do not know on the divorce paper to file if I cross of her maiden name and keep my last name, or cross off my last name
the marriage certificate has her name filled out but no mention of my last name as hers

what does the certificate say? her maiden name or your last name? if it's really to hard to determine, you can always put both her maiden and your last name on there and explain what's going on.

the lawyers already confirmed to use her maiden name since there has been no paperwork of a name change
they also told me if there was an issue with the last name it wont delay the divorce
