Section 9. (a) If the court finds that a parent is chargeable with the support of a child, the court shall make an order in accordance with subsection (c) requiring a parent to pay weekly or at other fixed periods a sum for and toward the current support and maintenance of such child. The court may make appropriate orders of maintenance, support and education for any child who has attained age eighteen but who has not attained age twenty-one, who is domiciled in the home of a parent and is principally dependent upon said parent for maintenance. The court may make appropriate orders of maintenance, support and education for any child who has attained age twenty-one but who has not attained age twenty-three if such child is domiciled in the home of a parent, and is principally dependent upon said parent for maintenance due to the enrollment of such child in an educational program, excluding educational costs beyond an undergraduate degree. Upon the petition of a party, the court shall also order past support for the period from the birth of the child to the entry of the order, taking into consideration the parent's ability to pay under subsection (c) and any support provided by the parent during such period. An order or judgment of support pursuant to this chapter shall be entered notwithstanding the default of the defendant or the defendant's failure to appear personally upon a showing that notice was served in accordance with the applicable rules of court. For good cause shown, the court may set aside an entry of default and, if a judgment has been entered, may likewise set it aside in accordance with rule 60(b) of the Massachusetts Rules of Domestic Relations Procedure. An order may be entered requiring a parent chargeable with support to reimburse the another parent or the department of transitional assistance or the office of Medicaid or the executive office of health and human services for medical expenses attributable to the child or associated with childbirth or resulting from the pregnancy.

If the court makes an order or judgment for maintenance or support of a child, the court shall require either parent to provide health care coverage for the child if such coverage is available at reasonable cost and accessible to the child. The court may require the obligor to pay an amount toward the obligee's cost of health care coverage or toward uninsured medical expenses on behalf of the child. If the court determines that an order for health care coverage is not in the best interest of the child or creates an undue hardship for either parent, the court shall enter written findings.

If the child is enrolled in MassHealth, an equivalent program in another state pursuant to 42 U.S.C. 1397aa et seq. or 42 U.S.C. 1396a et seq. or an equivalent program in another state that is substantially similar to the program established in chapter 118E, the court shall order the obligee to maintain coverage as long as the child remains eligible; provided, however, that the court may also order the obligor to enroll the child in private health insurance if: (i) private health insurance is available to the obligor at reasonable cost and accessible to the child; (ii) enrollment in the insurance is in the best interest of the child; and (iii) enrollment in the insurance will not create an undue hardship for the obligor or the obligee.

If the IV-D agency under chapter 119A is responsible for enforcing the order, the court shall order the parents to notify the IV-D agency of any changes in the availability and terms of health care coverage. For the purposes of this section: (i) health care coverage shall be deemed reasonable in cost if the cost to the party ordered to provide health care coverage does not exceed 5 per cent of the gross income of the party; (ii) health care coverage shall be deemed accessible to the child if covered services are available within 15 miles of the child's primary residence; (iii) health care coverage includes private health insurance available through employment, union affiliation or otherwise, and public health coverage administered by the Title XIX agency; and (iv) private health insurance shall be deemed not available at reasonable cost to an obligor or obligee whose gross income does not exceed 150 per cent of the federal poverty guidelines for the family size or who receives MassHealth on behalf of the obligor, the obligee or the child.

(b) Upon demand by either party, including the IV–D agency, the other party shall be compelled to provide a financial statement, except that the IV–D agency shall not be compelled to provide a financial statement for a recipient of public assistance, and, provided further, if no party makes such a demand, the court may require a financial statement of each party.

(c) In determining the amount of the child support obligation or in approving the agreement of the parties, the court shall apply the child support guidelines promulgated by the chief justice of the trial court. There shall be a rebuttable presumption that the amount resulting from application of the guidelines is the appropriate amount of child support to be ordered. If, after taking into consideration the best interests of the child, the court determines that a party has overcome such presumption, the court shall make specific written findings indicating the amount of the order that would result from application of the guidelines; that the guidelines amount would be unjust or inappropriate under the circumstances; the specific facts of the case which justify departure from the guidelines; and that such departure is consistent with the best interests of the child. In the event that no child support guidelines are in effect, the court shall make such order as is in the best interests of the child, taking into consideration the financial ability and earning capacity of the parents of the child.

(d) It shall not be a defense that the parent from whom support is sought has ceased to have custody or the right to custody of a minor child for whom support is sought, or that the custodial parent is interfering with the other parent's right of visitation.

(e) If the child on whose behalf an order of support is sought is a recipient of benefits pursuant to chapter 117, 118 or 119 and the department of transitional assistance, the department of children and families, the division of medical assistance or any other public assistance program has not been made a party as required by section 5, the court shall notify the IV–D agency of the order or judgment of support.

(f) In determining the amount to be paid, the court, in addition to applying the standards established by the chief justice of the trial court, shall determine whether the obligor is responsible for the maintenance or support of any other children of the obligor even if a court order for such maintenance or support does not exist. If the court determines that such responsibility does, in fact, exist and that such obligor is fulfilling such responsibility, such court shall take into consideration such responsibility in setting the amount to be paid under the current order for maintenance or support.
