If you are searching for a St. Louis divorce lawyer, your case will be heard by the 22nd Judicial Circuit Court, the trial court that serves the City of St. Louis. Unlike the surrounding St. Louis County (a separate jurisdiction in Clayton), the City of St. Louis is its own independent court system. You file downtown at the Civil Courts Building on Tucker Boulevard, a few blocks from the Gateway Arch and Citygarden. Missouri law (RSMo Chapter 452) sets a 90-day residency rule and a 30-day waiting period before any judge can sign your decree. The figures and logistics below are verified as of February 2026.

How do I file for divorce in St. Louis, Missouri?
To file for divorce in St. Louis, you submit a Petition for Dissolution of Marriage to the 22nd Judicial Circuit Court Circuit Clerk at 10 North Tucker Boulevard, pay a filing fee of roughly $130-$165, and arrange service on your spouse. Missouri is a no-fault state under RSMo § 452.305, so you only allege the marriage is irretrievably broken.
The Circuit Clerk's Office sits on the 3rd floor of the Civil Courts Building and is open weekdays from 8:30 a.m. to 5:00 p.m. Most attorneys submit your petition through Missouri's electronic filing system rather than walking paper to the counter, but self-represented filers can file in person. After filing, your spouse (the respondent) must be served, typically by the City Sheriff for $25-$75 or by a private process server for $50-$200. If your spouse signs an Entry of Appearance and Waiver of Service, you skip the service step entirely, which is common in uncontested City of St. Louis cases where both parties already agree on the major terms.
Where do I file for divorce in St. Louis? (which courthouse)
You file in the City of St. Louis at the Civil Courts Building, 10 North Tucker Boulevard, St. Louis, MO 63101, home to the 22nd Judicial Circuit Court Circuit Clerk. This downtown building, not the St. Louis County courthouse in Clayton, handles every dissolution for residents of the City of St. Louis. The clerk's office is on the 3rd floor.
The distinction matters because "St. Louis" refers to two separate legal jurisdictions. The City of St. Louis became independent from St. Louis County in 1876 and runs its own 22nd Circuit. If you live in a City neighborhood such as Tower Grove, the Central West End, Soulard, Dogtown, or South City, you file downtown at Tucker Boulevard. If you live in a County municipality such as Kirkwood, Florissant, or Chesterfield, you file at the St. Louis County Circuit Court in Clayton instead. Filing in the wrong court wastes your filing fee and delays the case, so confirm your address falls inside City limits before you submit. The 22nd Circuit also operates from the nearby Carnahan Courthouse and Cahill Courts Building at Market Street and Tucker, where hearings and trials are held.
How much does a divorce lawyer cost in St. Louis?
A St. Louis divorce lawyer generally charges $250 to $400 per hour, with most requiring a retainer of $2,500 to $5,000 up front. An uncontested City of St. Louis divorce with full agreement often resolves for a $1,500-$3,500 flat fee, while a contested case involving custody or business assets commonly runs $7,000-$15,000 or more once discovery, depositions, and trial preparation are added.
The filing fee itself is a small slice of the total, roughly $130-$165 paid to the 22nd Circuit Clerk, and cases with minor children typically cost $75-$100 more at filing due to additional fees. Beyond the lawyer and filing fee, budget for service of process ($25-$200), and a parenting education class ($25-$75) required when minor children are involved under City of St. Louis local rules. If you cannot afford to file, Missouri courts grant a fee waiver to applicants who submit a Motion and Affidavit in Support of Request to Proceed as a Poor Person; courts routinely approve waivers for households receiving SNAP, TANF, or Medicaid, or at or below 125% of the federal poverty level.

How long does a divorce take in St. Louis?
The fastest possible divorce in St. Louis is about 30 days, because RSMo § 452.305 bars a judge from entering a decree until 30 days have passed since the petition was filed. In practice, a truly uncontested City of St. Louis case with a signed marital settlement agreement and parenting plan usually finalizes in 30 to 90 days. Contested cases take far longer.
When spouses disagree about custody, support, or how to divide the marital home, a contested case in the 22nd Circuit commonly runs 9 to 18 months. The timeline stretches because of discovery, mandatory mediation in custody disputes, financial disclosure exchanges, and the court's trial calendar. The 22nd Judicial Circuit processes roughly 40,000 new civil and criminal cases each year, so docket congestion downtown can add weeks between hearings. Cases involving a closely held business, a contested valuation, or a custody evaluation under RSMo § 452.375 sit at the longer end of that range. Settling before trial is the single biggest factor in shortening your timeline.
What are the residency requirements to file in St. Louis city?
To file for divorce in the City of St. Louis, at least one spouse must have lived in Missouri for 90 days immediately before filing the petition, under RSMo § 452.305. Only one spouse needs to meet this requirement, and Missouri imposes no separate county-level residency rule, so City residents qualify the same way as anyone statewide.
The 90-day rule is jurisdictional, meaning the judge cannot enter a final judgment unless the requirement is satisfied. You may file your petition before the 90 days elapse, but the decree must wait until residency is established. Military members stationed in Missouri for the preceding 90 days qualify even without civilian residency. Because there is no City-specific residency add-on, the practical question is simply whether you or your spouse has lived somewhere in Missouri (City of St. Louis included) for the three months before filing. After the petition is filed, the separate 30-day waiting period begins to run, so the earliest a City of St. Louis decree can issue is 30 days from your filing date.
How is property and custody decided in a St. Louis divorce?
Missouri is an equitable-distribution state under RSMo § 452.330, meaning the 22nd Circuit divides marital property in proportions it deems just, not automatically 50/50. The court first sets aside each spouse's non-marital property, then divides marital assets and debts after weighing factors including each spouse's economic circumstances, contributions (including as a homemaker), and any misconduct during the marriage.
Property acquired by either spouse during the marriage is presumed marital, whether titled in one name or both, while gifts, inheritances, and pre-marriage assets generally stay separate. For children, custody follows the best-interests standard in RSMo § 452.375. Since Senate Bill 35 took effect in August 2023, Missouri courts apply a rebuttable presumption that equal or approximately equal parenting time serves the child's best interests; a parent opposing 50/50 must prove by a preponderance of the evidence that it would harm the child. Missouri uses the terms legal custody (decision-making) and physical custody (where the child lives), and the court can order joint or sole arrangements of either.
