(a) The State Comptroller will notify the county treasurer of each county of the name and location of each depository authorized to receive court and trust funds and moneys paid into courts of record in said county and of the maximum amount of such funds and moneys which may be placed on deposit at each depository.
(b) All court and trust funds and moneys paid into courts of record must be deposited in a designated depository. All such funds and money received by a county treasurer shall be deposited no later than the close of the next business day following receipt.
(c) Whenever the balance of court and trust funds and moneys paid into courts of record in a depository shall exceed 95 percent of the amount fixed by the State Comptroller as the maximum amount of such funds which may be deposited in such depository, the county treasurer shall immediately notify the State Comptroller. A county treasurer may notify the State Comptroller at any earlier time if the county treasurer deems that circumstances warrant that the State Comptroller be made aware of a given situation. Notification must be in writing sent by first class mail except that in cases of perceived emergencies the county treasurer may telephone the Bureau of Cash and Debt Management in the Office of the State Comptroller and confirm by facsimile transmission or first class mail. When the balance of the deposits equals 100 percent of the amount so fixed, the county treasurer shall immediately notify the Bureau of Cash and Debt Management in the Office of the State Comptroller by telephone and confirm by facsimile transmission to seek an amendment to the depository's Certificate of Eligibility to increase the maximum amount authorized to be deposited in such depository.
(d) Funds held for particular actions or proceedings may be pooled into a common bank account provided that the designated depository keeps a separate book entry account for each action or proceeding for which funds or moneys are deposited setting forth:
1. (1) the name of the court;
2. (2) the title of the action or proceeding;
3. (3) the amount deposited;
4. (4) the amount of any additional deposits;
5. (5) the amount of interest credited; and
6. (6) the amount of each withdrawal.
(e) Each deposit must be accompanied by a deposit statement of the county treasurer setting forth the name of the court, the title of the action or proceeding and the amount deposited.
