(a) The IV-D agency shall, subject to appropriation, employ personnel, develop automated collection, disbursement and data systems, and establish field offices to carry out its responsibilities. Said IV-D agency is also authorized to contract with other public and private agencies to carry out its responsibilities. The IV-D agency shall have in operation a single statewide automated data processing information retrieval system which has the capability to perform the tasks specified by Title IV, Part D of the Social Security Act. The automated system shall include a registry, which shall be known as the "state case registry", that contains records with respect to each case in which IV-D services are being provided by the IV-D agency pursuant to Title IV, Part D of the Social Security Act; and with respect to all other cases, including cases for which the IV-D agency only collects and disburses income withholding payments, each support order established or modified in the commonwealth on or after October 1, 1998. Such records for all cases shall use standardized data elements for both parents, such as names, social security numbers, dates of birth and other such information as the IV-D agency deems appropriate or as the federal secretary of health and human services may require. Each case record in the state case registry with respect to which IV-D services are being provided and with respect to which a support order has been established shall include a record of the amount of monthly or other periodic support owed under the order, and other amounts, including arrearages, interest or late payment penalties, and fees, due or overdue under the order; any such amounts collected; the distribution of such collected amounts; the date of birth, and beginning not later than October 1, 1999, the social security number of each child for whom the order requires the provision of support; and the amount of any lien imposed pursuant to section 6. The IV-D agency shall promptly establish and update, maintain, and regularly monitor case records in the state case registry with respect to which IV-D services are being provided on the basis of information on administrative actions and administrative and judicial proceedings and orders relating to paternity and support, information obtained from comparison with federal, state, or local sources of information, information on support collections and distributions, and any other relevant information. With respect to all other cases in the state case registry which are not receiving IV-D services, including cases for which the IV-D agency only collects and disburses income withholding payments, the IV-D agency shall update the information required by this section upon provision of such information by the court or the parties.
Each party to any paternity or child support proceeding, whether or not a recipient of IV-D services, is required, subject to privacy and safety safeguards as provided in section 5A, to file with the state case registry upon entry of an order, and to update as appropriate, information on location and identity of the party, including social security number, residential and mailing addresses, telephone number, driver's license number, and name, address, and telephone number of employer. In any subsequent child support enforcement action between the parties, upon sufficient showing that diligent effort has been made to ascertain the location of such a party, the court shall deem due process requirements for notice and service of process to be met with respect to the party, upon delivery of written notice to the most recent residential or employer address filed with the state case registry.
