Can trustees of trust require the beneficiaries sign a form before they distribute assets?

Have they done a good job? We ask for a release all the time it closes the books. If they haven't done a good job, then later I suppose you could sue them, and assert that the release was coerced.

It depends on the legal document - they can't have you waive negligence and even if you sign something that says they weren't negligent, it wouldn't prohibit you from suing them for negligence down the road. Other than that, it would depend on the document assigning them trustee. My suggestion is to retain an attorney if you feel they haven't done their job or you feel you are being unduly coerced.

No. They cannot require this, if you have questions about the administration of the trust. If you have questions about the administration of a trust, you should go to Probate Court, though you probably will need to hie an attorney. But, if you don't have any reason to question the administration of the trust, the only way you will get your distribution is to sign the document.
