Application Scenario, How Do You Handle This?

[Peter K.]

Took an application on a SFR from a single person this morning. I tell them I need an application filled out by each adult. Applicant told me it was just her. Facebook shows me she just got married in the last two months. She hasn't lied to me since I didn't ask marital status, but I would be shocked if the husband didn't move in too.

What would BP do?  Ask for the husband to fill out an app?  Deny?  If so, on what grounds?
