Legal Separation in Oklahoma: Alimony Without Divorce Explained
Independently fact-checked against primary sources (last audited October 8, 2026). · 1 primary source cited on this page. How we verify our legal content
Oklahoma's statutes refer to a "legal separation" proceeding, but the main court remedy short of divorce is 43 O.S. 129, alimony without divorce. Under it, a spouse "may obtain alimony from the other without a divorce, in an action brought for that purpose in the district court, for any of the causes for which a divorce may be granted," and 43 O.S. 108 lets the court then make orders for the children and divide property.

Jurisdiction scope: This article covers separation without divorce under Oklahoma Statutes Title 43, mainly 43 O.S. 101, 103, 105, 108, 109.1, 110, 111, 112.6, 129, 205 and 206. It does not cover Oklahoma case law, inheritance effects, how child support guidelines apply in these cases, tax or insurance consequences, court forms, or other states' law. For divorce, see Oklahoma divorce laws.
Does Oklahoma have legal separation?
Oklahoma's statutes use the term, but they do not contain a stand-alone legal separation chapter. No section of Title 43, the marriage title, sets out a stand-alone legal separation action. The terms appear inside other sections:
- Caption. 43 O.S. 105(A): "A proceeding for dissolution of marriage, an annulment of a marriage, or a legal separation shall be titled 'In re the Marriage of _______ and ______'."
- Venue. 43 O.S. 103(A)(2): "An action for legal separation may be brought in the county in which either party is a resident at the time of the filing of the petition."
- Automatic injunction. 43 O.S. 110(A)(1) applies on the filing of a petition "for dissolution of marriage, annulment of a marriage or legal separation."
- Contempt. 43 O.S. 111: "Any order pertaining to the division of property pursuant to a divorce or separate maintenance action, if willfully disobeyed, may be enforced as an indirect contempt of court."
- Attorney fees. 43 O.S. 112.6 entitles a domestic violence victim to attorney fees in a "dissolution of marriage or separate maintenance or custody proceeding."
The main court remedy that does not end the marriage is 43 O.S. 129.
Alimony without divorce (43 O.S. 129)
43 O.S. 129 provides:
"The wife or husband may obtain alimony from the other without a divorce, in an action brought for that purpose in the district court, for any of the causes for which a divorce may be granted. Either may make the same defense to such action as he might to an action for divorce, and may, for sufficient cause, obtain a divorce from the other in such action."
Three points follow from that text. The case is filed in district court. The spouse asking for alimony must show a divorce ground. And the other spouse may raise the same defenses as in a divorce, or may seek a divorce in the same case.
Grounds: the twelve divorce causes
Because 43 O.S. 129 borrows "any of the causes for which a divorce may be granted," the grounds come from 43 O.S. 101:
| Divorce ground under 43 O.S. 101 | |
|---|---|
| 1 | Abandonment for one year |
| 2 | Adultery |
| 3 | Impotency |
| 4 | The wife, at the time of the marriage, was pregnant by another |
| 5 | Extreme cruelty |
| 6 | Fraudulent contract |
| 7 | Incompatibility |
| 8 | Habitual drunkenness |
| 9 | Gross neglect of duty |
| 10 | Imprisonment under a felony sentence |
| 11 | An out-of-state divorce decree that does not release the other party |
| 12 | Insanity for five years with institutional confinement, after examination by three physicians |
Living apart is not one of the twelve listed grounds.
What the court can order
When the court grants alimony without a divorce, 43 O.S. 108 provides that it "may for good cause shown make such order as may be proper for the custody, maintenance and education of the children, and for the control and equitable division and disposition of the property of the parties, or of either of them, as may be proper, equitable and just." The same power applies "in any case where a divorce is refused."
In practice, that means a court in an alimony-without-divorce case can address:
- Alimony between the spouses (43 O.S. 129). See Oklahoma alimony laws.
- Custody, maintenance and education of the children (43 O.S. 108). See Oklahoma child custody laws and Oklahoma child support laws.
- Control and equitable division of property (43 O.S. 108).
While the case is pending, 43 O.S. 110 puts an automatic temporary injunction in effect against both parties once a legal separation petition is filed and personally served with the summons, and provides for temporary orders.
Residency and where to file
The venue rule for legal separation is in 43 O.S. 103(A)(2): the action may be brought in the county where either party resides when the petition is filed.
Oklahoma's six-month state residency rule, 43 O.S. 102, is worded for "an action for divorce or annulment of a marriage." This page does not cover whether a residency period applies to an alimony-without-divorce or legal separation case; ask the court clerk or an Oklahoma lawyer before filing.
Custody while separated but not divorced
Parents who are separated without any divorce case have another route. Under 43 O.S. 109.1, "If the parents of a minor unmarried child are separated without being divorced, the judge of the district court, upon application of either parent, may issue any civil process necessary to inquire into the custody of said minor unmarried child."
Separation agreements
Spouses can also separate by written agreement. Under 43 O.S. 205, a husband and wife "may agree in writing to an immediate separation, and may make provision for the support of either of them and of their children during such separation." 43 O.S. 206 makes their mutual consent "a sufficient consideration" for that agreement.
This page does not cover how Oklahoma courts treat a separation agreement in a later divorce or support case.
Moving from separation to divorce
Two sections let a separation case become a divorce case. 43 O.S. 129 lets the defending spouse, "for sufficient cause, obtain a divorce from the other in such action." 43 O.S. 106(A) lets a respondent plead dissolution, annulment or legal separation against the petitioner.
The sections cited on this page do not provide for automatic conversion of a separation into a divorce after a set period. A spouse who wants a divorce later needs a ground under 43 O.S. 101.
You are still married
An alimony-without-divorce order does not end the marriage. Under 43 O.S. 122, it is a divorce that "shall operate as a dissolution of the marriage contract," and the remarriage restrictions in 43 O.S. 123 attach to divorce decrees. This page does not cover how a separation order affects inheritance or a surviving spouse's rights; ask an Oklahoma lawyer.
