About Jim
Jim Schleiffarth is an attorney admitted to practice in both Missouri and Illinois. He represents individuals and organizations whose matters cross state lines, handling the practical complications that come when two legal systems overlap. He is known among colleagues for steady courtroom presence and careful case preparation.
He trained in law and earned the credentials required for bar admission in two states. Early work included routine court appearances, client counseling, and drafting pleadings. Over time he expanded the geographic reach of his practice to serve clients on both sides of the Mississippi River. That choice meant learning procedural differences and local practice habits in multiple jurisdictions.
Across his career, Schleiffarth has handled cases that require attention to procedural detail and strategic timing. He has experience managing discovery disputes and coordinating filings across state courts. He also works on matters that involve regulatory compliance and civil procedures that differ between Illinois and Missouri. In many matters he serves as the principal point of contact for clients who prefer a single attorney to manage multi-jurisdictional tasks.
Colleagues describe him as pragmatic and steady under pressure. His courtroom manner is plain and direct. He prepares witnesses, argues evidentiary matters, and pursues practical resolutions when they are available. When cases proceed to trial, he focuses on clear themes and concise presentation rather than long-winded argument. Outside the courtroom he spends time reviewing changes to state rules and local court practices so his filings meet current requirements.
Today Schleiffarth maintains an active practice across Missouri and Illinois. He represents clients in matters that arise in both states and coordinates strategy where laws or procedures diverge. He is licensed in Missouri and Illinois and continues to accept cases that require cross-border attention, handling filings, hearings, and client counseling in both jurisdictions.
