Notice shall be sent by certified mail, return receipt requested, and also by separate first-class mail. Such certified mail notice shall be sufficient, although unclaimed or refused by the obligor, provided that the first-class mail notice is not returned to the sender undelivered. No additional service shall be required for any reason if notice by mail, in accordance with this section, appears to have been valid. In individual cases, if service by mail cannot be accomplished, the court may provide for any other means of service as is deemed necessary.
If the case was forwarded to the court by the 1V-D agency pursuant to G.L. c. 119A, s. 8, the court shall provide the obligor's notice to the agency, to be served by the agency upon the obligor in accordance with G.L. c. 273A, s. 10 and the provisions of this rule. If the case was not forwarded by the IV-D agency, the clerk's office shall itself notify the obligor.
