Tenant Wants Ex-Wife to Move In

[Hud Hudson]

My tenant has asked to move his ex-wife in.  She will not qualify as a tenant due to the terms and conditions of my screening and application criteria, primarily because she is unemployed.  I have told him that all occupants must have a lease agreement to be a resident.  Is there anything that I can do other than tell him that she must undergo the same application and screening process as any other potential tenant, and since she does not qualify she will not be permitted a lease agreement?  I envision endless adverse scenarios by permitting her to move in, even with a lease agreement.  And I would be discriminating if I didn't disqualify her based on the application and screening terms and conditions.

Many thanks!
