10- 144 C.M.R. ch. 351, § 21-5
The Department shall render a decision after hearing without undue delay as to whether the obligor is in compliance with the obligor's support order. The only issues that may be decided are whether the obligor is required to pay child support under the support order for which the Division issued a notice of noncompliance and, if so, whether the obligor is in compliance with that support order. The decision must be based on the hearing record and the rules adopted by the Commissioner. The decision must inform the obligor that the obligor may file a petition for judicial review of the decision within 30 days of the date of the decision. The Department shall send an attested copy of the decision to the obligor by regular mail to the obligor's most recent address of record.
The obligor is presumed to have received the decision within three (3) days of mailing.
