Read the trust agreement. Look for rules regarding creating trust checking accounts. Note the requirements, such as using a specific bank, if any. Follow the trust requirements if the agreement has rules for checking accounts.
Contact local banks. Ask if the bank provides trust checking accounts. Ask for a list of the documents required to open the account, the minimum opening deposit amount and a fee schedule. Compare fee schedules when selecting a bank.
Gather the required documents and the opening deposit amount. Documentation varies by bank, but you commonly need at least two valid forms of identification -- for example, state identification or a U.S. passport and a birth certificate -- and the original trust agreement. Locate any income tax papers you have regarding the trust, if any.
Visit the bank in person to open the account. Bring all required documents and the first deposit with you. Tell the clerk you want to open a trust checking account. Follow the bank's application procedures.
Make copies of the checking account papers the bank gives you. Put the papers with the original trust agreement. Add the account information, including bank name and account number, to the trust's property list.
