The largest city
in St. Charles County.
O’Fallon is the largest city in St. Charles County by population and one of the larger municipalities in the metro overall. The Highway K corridor runs through the heart of the city, and a substantial share of the traffic and personal injury work that originates in O’Fallon traces to that road and to the I-70 / I-64 split a few miles south. The legal work spans the full practice spectrum, but the volume tilts toward traffic court and the suburban-family caseload that comes with a younger, growing city.
Thirty minutes east,
on I-70.
From central O’Fallon, our Florissant office is about thirty minutes east on I-70 across the Missouri River. We handle most O’Fallon work by phone and video, with in-person meetings when the case calls for them. We drive to O’Fallon for home signings and court appearances. Hablamos español.

Why traffic court
defines so much of the work.
O’Fallon’s population is around 90,000, which makes it the largest city in St. Charles County and one of the largest in the metro. With that population comes a heavy traffic-court docket. Highway K, the I-70 service roads, and the surrounding road network produce a steady volume of speeding, careless-driving, and accident-related citations. For most drivers the goal at municipal court is to keep the violation off the driving record — through amendment to a non-moving violation, through deferred prosecution, or through dismissal where defenses exist. The disposition path matters because Missouri points stack across municipalities, and a clean record is worth real money in insurance premiums and (for CDL holders) in employability.
On the personal injury side, the I-70 / I-64 split south of O’Fallon produces highway-speed collisions, and the Highway K intersections produce the typical suburban-arterial pattern of rear-end and angle crashes. Estate planning for O’Fallon families looks similar to St. Peters — younger demographics, mortgages still being paid, guardianship designations for minor children, and life insurance considerations driving the structure.

First-call questions for an O’Fallon traffic matter: for traffic matters, whether you have a CDL (the disposition strategy changes if you do), how many points are currently on your record, and whether you have pending matters in any other Missouri municipality. Stacking points across courts can trigger administrative suspension we can sometimes avoid by sequencing the dispositions.
For O’Fallon families, estate planning often opens the door to the longer-horizon work. Younger parents need guardianship designations and life-insurance trusts; mid-career professionals need beneficiary updates and the occasional rollover IRA review; pre-retirement clients need to think about long-term care risk. We carry all three stages in the same conversation.
Most O’Fallon clients first call us about a ticket. The conversation often expands — an estate plan, a will update, a follow-up on a parent’s probate. We handle whatever the family needs.
O'Fallon legal FAQ —
straight answers.
The questions O'Fallon residents and businesses ask most often. General information; specific facts always change the analysis.
What court handles felony cases for O'Fallon residents?
Felony charges originating in O'Fallon are filed in the St. Charles County Circuit Court at 300 North Second Street, St. Charles. Initial appearances, preliminary hearings, and bond review are heard there before the case is assigned to a trial division. We appear in St. Charles County regularly.
Where is O'Fallon’s municipal court located?
The O'Fallon Municipal Court at City Hall handles ordinance violations. Speeding citations, careless-and-imprudent tickets, accident citations, and minor ordinance matters are heard there rather than at the St. Charles County Circuit Court.
How far is your office from O'Fallon?
Our office at 580 N. U.S. Highway 67, Suite 4 in Florissant is about 35 minutes northwest of Florissant via I-70. Many O'Fallon clients meet us in person; others handle the entire matter by phone and video, with in-home signings available for estate planning.
What is the statute of limitations for a Missouri car accident?
Five years from the date of the accident for injury to a person (RSMo §516.120). Wrongful death is three years from the date of death (RSMo §537.100). Earlier action almost always produces a better result — evidence and witness memory fade.
Do you accept O'Fallon injury cases on a contingency-fee basis?
Yes. Personal injury and wrongful death cases are handled on contingency — you pay a fee only if we recover money on your behalf. The initial consultation is free.
