At a recent audit we discovered account where the firm was inactive and dissolved, however the account still shows transactions and very active. my reaction is, remove from NOW status and ask for account to close if in fact the business is dissolved.

IOTA means "Interest on Trust Account." Only a law firm has this type of account. If the law firm has ceased to exist all the funds in the account should have been paid out to its clients,. Under no circumstances should there be any ongoing activity.

Based on the information offered, you should reach out to the bar association...
