US Immigration from Scotland

I don't know which forum to post this in - please move as appropriate

As per the title:
We're in the middle of a mortgage transaction. The underwriter of the title company stated that they will not accept my USCIS issued ID because (and I'm quoting this straight from an email!) "Immigration just puts down whatever name she tells them."

I do not have a DL
My passport with my visa is in my former married name and clearly I am not going to use that to go onto the title to a home I share with my loving husband.

Is there anything I can print off/refer them to? We already sent them a state appropriate statute which they told us is "open to interpretation."

I am so furious right now but I need something I can present to them.

Thank you. Any advice appreciated

PS I have conducted all my affairs, payroll, tax, bank accounts, travel etc with my GC. No issues.
