Investors & landlords

I know but two of them are refusing to give me their SS#s which (I've learned) is going to require me to attach affidavits, etc. to the return and potentially incur a fine, etc.  I'm trying to avoid that if possible. There's no mention in the trust instrument that I have to include carryover loss in distribution, I would do it obviously if everyone was cooperating.   One of them DID give it to me, so I could just give it all to them but I guess that would appear as preference.  It's a thankless job being a trustee. 🙄
