How we match your O'Fallon criminal defense case
When you submit a O'Fallon criminal defense 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.
Case type
A criminal defense matter needs someone who handles criminal defense work day to day, not a generalist. Practice area is the first filter.
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.
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.
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.
