Yes, you need to inform the Office of Professional Regulation when you open a new trust account. This is best done by sending a letter with your new trust account information (name and address of financial institution, account number and title of account) to: Office of Professional Regulation, Attn: Lawyers Trust Account, Iowa Judicial Building, 1111 East Court Avenue, Des Moines, Iowa, 50319. Your trust account information is also reported and confirmed annually on your client security report form. If you create or change your trust account you have an affirmative duty to supplement or amend your answers on the client security report form within 30 days of the change or creation. The written notice mailed to us will function as that supplement.
