A statement not specifically covered by any law but having equivalent circumstantial guarantees of trustworthiness shall not be excluded by the hearsay rule, if the court determines that:
However, a statement may not be admitted under this Code section unless the proponent of it makes known to the adverse party, sufficiently in advance of the trial or hearing to provide the adverse party with a fair opportunity to prepare to meet it, the proponent's intention to offer the statement and the particulars of it, including the name and address of the declarant.
