Owner Authorization?

I would tell her that she needs prior authorization before expecting to be reimbursed for anything.

Per German law, all registered residents must pay a radio and TV tax to the local authorities.

This is not an owned home therefore I don’t believe the rights of spouse, significant other carry over.Tell the husband to immediately call authorities and you as landlord when soon-to-be ex-wife tries to re-enter.

I suggested calling her lender via conference call so we can clarify steps with her authorizing me to speak on her behalf, but haven't heard from her since then.My understanding is that she needs to send our PA to her lender for approval and they will deal with our lender.

You need to get an attorney involved ASAP.Look for someone through the Mass Bar Association who has a track record in defending these kinds of cases. https://www.massbar.org/public/lawyer-referral-ser...My understanding is the same as yours - if a property is not inspected and approved by the local housing administration (the local authority that administers Section 8), then Section 8 renters are not able to rent there.It's just a guess, but if your PM said something like "we don't rent to section 8", that could be the basis of the complaint.
