Okla. Stat. tit. 43, § 43-118D: Computation of child support as percentage of parents'

combined gross income - Prospective adjustment - Transportation

expenses - Support order summary form.

A. All child support shall be computed as a percentage of the

combined gross income of both parents. The Child Support Guideline

Schedule as provided in Section 119 of Title 43 of the Oklahoma

Statutes shall be used for such computation. The child support

obligation of each parent shall be computed. The share of the

obligor shall be paid monthly to the obligee and shall be due on a

specific date.

B. In cases in which one parent has sole physical custody, the

adjusted monthly gross income of both parents shall be added

together and the Child Support Guideline Schedule consulted for the

total combined base monthly obligation for child support.

C. After the total combined child support is determined, the

percentage share of each parent shall be allocated by computing the

percentage contribution of each parent to the combined adjusted

gross income and allocating that same percentage to the child

support obligation to determine the base child support obligation of

each parent.

D. 1. In cases of split physical custody, where each parent is

awarded physical custody of at least one of the children for whom

the parents are responsible, the child support obligation for each

parent shall be calculated by application of the child support

guidelines for each custodial arrangement.

2. The parent with the larger child support obligation shall

pay the difference between the two amounts to the parent with the

smaller child support obligation.

E. Child support shall be computed as set forth in subsections

A through D of this section in every case, regardless of whether the

custodial arrangement is designated as sole custody or joint

custody.

F. The court, to the extent reasonably possible, shall make

provision in an order for prospective adjustment of support to

address any foreseen changes including, but not limited to, changes

in medical insurance, child care expenses, medical expenses,

extraordinary costs, and the satisfaction of jointly acquired debt

of the parents used as a deduction from the gross income of a

parent.

G. Transportation expenses of a child between the homes of the

parents may be divided between the parents in proportion to their

adjusted gross income, so long as the payment of such expenses does

not significantly reduce the ability of the custodial parent to

provide for the basic needs of the child.

H. The social security numbers of both parents and the children

who are the subject of a paternity or child support order shall be

included in the support order summary form provided for in Section

120 of Title 43 of the Oklahoma Statutes.

I. A completed support order summary form shall be presented to

the judge with all paternity and child support orders where the

Department of Human Services is not a necessary party pursuant to

Section 112 of Title 43 of the Oklahoma Statutes. No such order

shall be signed by the judge without presentation of the form.
