Child Support Orders
Child support order
15.1 (1) A court of competent jurisdiction may, on application by either or both spouses, make an order requiring a spouse to pay for the support of any or all children of the marriage.
Interim order
(2) Where an application is made under subsection (1), the court may, on application by either or both spouses, make an interim order requiring a spouse to pay for the support of any or all children of the marriage, pending the determination of the application under subsection (1).
Guidelines apply
(3) A court making an order under subsection (1) or an interim order under subsection (2) shall do so in accordance with the applicable guidelines.
Terms and conditions
(4) The court may make an order under subsection (1) or an interim order under subsection (2) for a definite or indefinite period or until a specified event occurs, and may impose terms, conditions or restrictions in connection with the order or interim order as it thinks fit and just.
Court may take agreement, etc., into account
(5) Notwithstanding subsection (3), a court may award an amount that is different from the amount that would be determined in accordance with the applicable guidelines if the court is satisfied
(a) that special provisions in an order, a judgment or a written agreement respecting the financial obligations of the spouses, or the division or transfer of their property, directly or indirectly benefit a child, or that special provisions have otherwise been made for the benefit of a child; and
(b) that the application of the applicable guidelines would result in an amount of child support that is inequitable given those special provisions.
Reasons
(6) Where the court awards, pursuant to subsection (5), an amount that is different from the amount that would be determined in accordance with the applicable guidelines, the court shall record its reasons for having done so.
Consent orders
(7) Notwithstanding subsection (3), a court may award an amount that is different from the amount that would be determined in accordance with the applicable guidelines on the consent of both spouses if it is satisfied that reasonable arrangements have been made for the support of the child to whom the order relates.
Reasonable arrangements
(8) For the purposes of subsection (7), in determining whether reasonable arrangements have been made for the support of a child, the court shall have regard to the applicable guidelines. However, the court shall not consider the arrangements to be unreasonable solely because the amount of support agreed to is not the same as the amount that would otherwise have been determined in accordance with the applicable guidelines.
