Account—it may vary from state to state but in my state all interest in an attorney/client trust account does go to the state. I may be holding as much as a million as a down payment on a sale of a business, for several months, but i dont get that interest.
In answer to someone else’s question, i have only one trust account and funds from various clients are comingled. All subject to strict record keeping. They love to suspend or disbar you here for any impropriety in the trust account.
