How we match your O'Fallon family law case

When you submit a O'Fallon family law matter, we route it through a national network of independent partner firms and put it in front of the one that fits best — based on the kind of case it is, what it is likely to involve, where it has to be handled, and who has capacity to take it on now.

  1. Case type

    A family law matter needs someone who handles family law work day to day, not a generalist. Practice area is the first filter.

  2. Size and complexity

    Some firms are built for catastrophic injury and multi-party litigation; others resolve straightforward claims quickly. We weigh what your matter is likely to involve against how each firm actually works.

  3. Jurisdiction and licensing

    Your matter is decided under Missouri law, so it goes to an attorney licensed in Missouri who regularly appears where your case would be heard.

  4. Capacity and fit

    Availability, conflicts of interest and language all matter. If the best-fit firm cannot take your case, we route it to the next one that can — or tell you plainly when no one in the network is the right answer.

Every partner reviews your case for free. Injury and workers’ compensation matters are handled on contingency — no fee unless you win. Other matters are quoted upfront, before you commit to anything.

DearLegal provides marketing and matching services and is not a law firm. Submitting a case does not create an attorney-client relationship. Matches depend on case type, jurisdiction and firm availability.

Illustrative only. Your fee terms are set in a written agreement with your attorney and may include costs and expenses regardless of outcome.

Family Law matters in Missouri are usually a flat fee per filing — quoted before you commit, not billed by the hour.

Family law cases in Missouri are not handled on contingency. Missouri Rule of Professional Conduct 4-1.5(d)(1) — patterned on ABA Model Rule 1.5(d) — prohibits contingent fees in domestic relations matters where the fee is contingent on securing a divorce or on the amount of maintenance, support, or property settlement. Missouri family law attorneys charge hourly (billed against a retainer) or a flat fee for uncontested matters. Courts may award fees under Mo. Rev. Stat. § 452.355.

Exhibit F

O'Fallon family law questions, answered

Still unsure? Tell us what happened and a Missouri attorney will review it for free.

Generally yes. Dissolution cases are filed in the circuit court for the county where a spouse resides, which for most O'Fallon residents is St. Charles County. Missouri also has a residency requirement before you can file. An attorney can confirm you meet it and file in the right court.
Missouri courts decide legal and physical custody based on the best interests of the child, considering each parent's involvement, the child's adjustment to home and school, and each parent's willingness to support the other's relationship with the child. A written parenting plan is required. An attorney can help you propose a plan the court will accept.
Missouri requires a waiting period after filing before a dissolution can be finalized, and contested cases take longer. Other family matters, like challenging paternity or modifying an order, carry deadlines that vary by issue. A Missouri attorney can confirm the specific timelines that apply to your case.
At minimum, 30 days from filing — Missouri’s waiting period under Mo. Rev. Stat. § 452.305. Uncontested divorces typically finalize at or shortly after the 30-day mark. Contested cases generally take 6–12 months.
Yes — irretrievable breakdown is the primary ground under Mo. Rev. Stat. § 452.305. When one spouse denies breakdown, the court must find one of five factors (adultery, intolerable behavior, 6-month abandonment, 12-month mutual living apart, or 24-month consecutive living apart).
