Amends the Clerks of Court Act. Authorizes a circuit court clerk of any county to develop and maintain a will depository. Provides a procedure for the clerk to accept for safekeeping a testamentary instrument executed in compliance with the Probate Act of 1975, including a will, codicil, trust, or trust and one or more trust amendments. Allows a depositor to deposit a will with the clerk if the depositor certifies in writing that the depositor is unable to locate the testator after a diligent search. Creates a procedure for the clerk to follow in accepting, keeping, and returning these documents. Allows the clerk to charge a fee of $25 for each will deposited, and the clerk may not collect a separate fee for additional documents concurrently deposited in relation to a single testator or for a single joint will prepared for a husband and wife.
