If you live in Columbia and are starting a divorce, your case goes through the Boone County Circuit Court, part of Missouri's 13th Judicial Circuit. The courthouse sits at 705 E. Walnut St. in downtown Columbia, inside the Boone County Government Complex, a few blocks from the University of Missouri campus and the District. Missouri is a no-fault state, so the only ground you need to prove is that the marriage is "irretrievably broken" under RSMo § 452.305. This page explains where Columbia residents file, what it costs, how long it takes, and the Missouri statutes that control property, support, and custody.

How do I file for divorce in Columbia, Missouri?
To file for divorce in Columbia, you submit a Petition for Dissolution of Marriage (Missouri form CAFC001) to the Boone County Circuit Clerk at 705 E. Walnut St., and pay a filing fee of roughly $132 to $162 as of early 2026. At least one spouse must have lived in Missouri for 90 days before filing under RSMo § 452.305. The Circuit Clerk's Office is open Monday through Friday, 8:00 a.m. to 5:00 p.m. After filing, you arrange service on your spouse, either by sheriff or by a signed waiver of service. The spouse who files is the Petitioner; the spouse who is served is the Respondent. If you and your spouse agree on every issue, you can file a joint or uncontested case with a marital settlement agreement and a parenting plan, which moves faster than a contested filing. Boone County cases since August 1993 are searchable electronically, while older records require an in-person visit to the courthouse.
Where do I file for divorce in Columbia? (which courthouse)
Columbia residents file at the Boone County Courthouse, 705 E. Walnut St., Columbia, MO 65201, the home of the 13th Judicial Circuit, which covers Boone and Callaway counties. The main court number is (573) 886-4000. The courthouse is the third built on this downtown site and anchors the Boone County Government Complex. Metered street parking surrounds the building, and a public parking garage stands at 8th and Walnut, directly across from the courthouse entrance. Missouri does not impose a separate county residency rule, so you may file in the county where either spouse resides under RSMo § 452.305. For most Columbia couples, that is Boone County. If your spouse lives in a different Missouri county, you can still file here as long as you are a Boone County resident, though service fees may differ if the sheriff in another county must serve the papers.
How much does a divorce lawyer cost in Columbia?
A Columbia divorce lawyer typically bills $200 to $400 per hour, with most local family-law attorneys requesting an upfront retainer of $2,500 to $5,000. An uncontested divorce with full agreement often resolves for a flat fee of $1,500 to $3,500 plus the court filing fee. Contested cases involving custody disputes, business valuations, or significant assets can run $7,000 to $20,000 or more, depending on how many hearings and how much discovery the case requires. The court filing fee itself is separate, running about $132 to $162 in Boone County as of early 2026. To estimate your own total, use our divorce cost estimator. If money is tight, Mid-Missouri Legal Services and Legal Services of Missouri provide free help to qualifying low-income residents, and the court allows a fee waiver (in forma pauperis) for filers who cannot afford the filing cost.
How long does a divorce take in Columbia?
A divorce in Columbia takes a minimum of 30 days, because Missouri requires a 30-day waiting period between filing the petition and the court entering a judgment under RSMo § 452.305. In practice, a fully uncontested Boone County case with a signed settlement agreement and parenting plan often finalizes in 30 to 60 days. Contested cases that involve disputed custody, property valuation, or support take far longer, commonly 8 to 18 months, because of discovery, mediation, temporary-order hearings, and the court's trial calendar. The 30-day clock runs concurrently with the 90-day residency period, so a spouse who has already lived in Missouri 90 days can reach the earliest possible judgment 30 days after filing.

What are the residency requirements to file in Boone County?
To file for divorce in Boone County, at least one spouse must have resided in Missouri for 90 days immediately before filing the petition, or be a military member stationed in Missouri for that period, under RSMo § 452.305. Only one spouse needs to meet this requirement. The 90-day rule is jurisdictional, meaning the court cannot enter a final judgment until residency is satisfied, though you may file the petition first. Missouri does not add a separate county-level residency requirement, so a Columbia resident files in Boone County, and the divorce is valid statewide once granted.
How is property divided in a Columbia divorce?
Missouri is an equitable-distribution state, so a Boone County judge divides marital property fairly but not necessarily 50/50 under RSMo § 452.330. The court first sets aside each spouse's nonmarital (separate) property, then divides marital property and debts using statutory factors: the economic circumstances of each spouse, each spouse's contribution to acquiring the property (including as a homemaker), the value of separate property, the conduct of the parties during the marriage, and custodial arrangements for any minor children. Marital property generally includes assets acquired during the marriage, while gifts, inheritances, and pre-marriage property remain separate. For retirement accounts, a Qualified Domestic Relations Order may be needed; our property division resources walk through the process.
How does child custody work in Columbia?
Boone County courts decide custody based on the best interests of the child under RSMo § 452.375, weighing eight statutory factors including each parent's wishes, the child's relationships and adjustment, which parent better supports the child's contact with the other parent, and the mental and physical health of those involved. Missouri uses gender-neutral standards and gives no preference based on a parent's sex. Recent legislation, including Senate Bill 1026 signed in 2024, refined the framework to emphasize parental cooperation, the distance between homes, any history of substance use, and the child's reasonable input. Every custody judgment must include a written parenting plan. Estimate support obligations with our child support calculator.
Is spousal maintenance (alimony) available in Columbia divorces?
Missouri courts may award spousal maintenance when one spouse lacks sufficient property and income to meet reasonable needs, under RSMo § 452.335. The judge weighs the requesting spouse's financial resources, the time needed to acquire training for employment, the standard of living during the marriage, the duration of the marriage, and each party's conduct. While Missouri is no-fault for grounds, marital misconduct such as adultery can factor into a maintenance award. Maintenance may be modifiable or non-modifiable depending on the order. Estimate a possible award with our alimony estimator before discussing terms with a Columbia attorney.
