I know record retention is generally a state specific issue. HOWEVER- I am hoping this question is not.

We have documents that need to be destroyed. We are a small institution, so we don't send our documents anywhere for storage, we just keep them onsite.

We have trust records that belong to trust accounts that have been closed for over 7 years. My question is, how detailed do we have to be on the destruction log? Do we need to record just that it was a trust document that was destroyed or do we need to include details about the trust, such as the name and date of the documents?

"Trust documents" is a pretty broad category. Depending on the documents you are referring to, some State require permanent retention.

Sorry - back to State law.
