It shall be lawful for the personal representative to agree with his or her surety for the deposit of any or all moneys and other assets of the estate with a bank, safe deposit, or trust company authorized by law to do business as such, or other depository approved by the court if the deposit is otherwise proper, in such manner as to prevent the withdrawal of the moneys or other assets without the written consent of the surety or on order of the court made on such notice to the surety as the court may direct. However, the agreement shall not alter the liability of the personal representative or surety as fixed by the bond.
