Company was destroyed, trustee died, the rest of the company execs now live in another country. Assets have been distributed to the participants, but we don't know who should sign the final form 5500. Ideas? I have searched the DOL and IRS sites and it doesn't seem to address this exactly. We are the TPA only.

Who is paying your Company's bill for the TPA work, final filing, etc.? That might be a place to start....

No one is paying our bill. We are just trying to figure out if we need to send in a 5500, unsigned. That probably would trigger an audit, but at least they would have a 5500.
