Quick answer: Oklahoma has no alimony formula and no statutory list of factors. Under 43 O.S. § 121(B), either spouse may be allowed alimony out of the real and personal property of the other as the court shall think reasonable, having due regard to the value of that property, in real or personal property or a money judgment, payable in gross or in installments as the court deems just and equitable. A divorce decree that provides for periodic alimony must plainly state which part of each payment is support and which pertains to a division of property (§ 134(A)); payments for property division are irrevocable and not modifiable, while support alimony can be modified on proof of changed circumstances relating to need or ability to support that are substantial and continuing so as to make the decree unreasonable. The decree must provide that support ends on the recipient’s death or remarriage, and the voluntary cohabitation of the former spouse is a ground to modify. Modification applies only prospectively, from the date the motion is filed.
What this calculator shows
The calculator builds a monthly ceiling from the recipient’s shortfall and the payor’s ability to pay. It does not predict an award, because the amount and term are in the court’s discretion. The two kinds of alimony are in support alimony and alimony in lieu of property, termination and modification in death, remarriage, cohabitation and modification and how courts set the amount in how Oklahoma courts set the amount.
