N.D. Cent. Code § 43-23-14.1
Except as otherwise provided in this section, every broker, at all times, shall maintain in the broker's name or firm name, a separate, noninterest-bearing trust account designated as such in a federally insured financial institution in this state in which the broker immediately shall place as a demand deposit all funds not the broker's own coming into the broker's possession, in accordance with rules adopted by the commission. This requirement extends to funds in which the broker may have some future interest or claim and includes earnest money deposits. A broker may not commingle the broker's personal funds or other funds in a trust account, except a broker may deposit and keep a sum not to exceed five hundred dollars in the account from the broker's personal funds, which sum must be specifically identified and deposited to cover service charges related to the trust account. In conjunction with the account, the broker shall maintain at the broker's usual place of business, books, records, contracts, and other necessary documents so the adequacy of the account may be determined at any time. Trust accounts and other records must be open to inspection by the commission and the commission's duly authorized agents at all times during regular business hours at the broker's usual place of business.
A broker that does not accept trust funds in real estate brokerage transactions and which has applied for and received a waiver from the real estate commission is not required to maintain a designated trust account. However, if a broker does not maintain a trust account and later receives trust funds in a real estate brokerage transaction, the broker shall open a designated trust account as required by this section and deposit any trust funds in accordance with rules adopted by the commission. A broker shall maintain a record tracking the earnest money associated with all transactions even if the funds are deposited directly with the title company and the broker does not take possession of the funds.
