Finding a lawyer in Arnold

Arnold sits in Jefferson County near where the Meramec River meets the Mississippi, south of the city of St. Louis along the interstate corridor leading out of the metro area. Civil and criminal matters arising here are heard in the Jefferson County circuit court, which sits in the county seat of Hillsboro rather than in Arnold itself, so a lawyer who regularly travels there is worth asking about.

Legal issues people in Arnold bring to lawyers

Personal injury and car accident attorneys handle claims from crashes along the area's interstate and river-crossing traffic, decided under Missouri's comparative fault rule. Family and divorce lawyers guide Jefferson County residents through custody, child support and property division. Real estate attorneys work on home purchases and title issues tied to the area's residential growth south of St. Louis. Criminal defense and DUI lawyers represent clients facing charges filed in Jefferson County, including the separate license process that follows a DWI. Workers' compensation lawyers take on job-injury claims for residents employed at nearby St. Louis-area plants and warehouses. Estate planning and probate attorneys draft wills and trusts and guide families through the county's probate division.

Choosing a law firm in Arnold

Confirm an attorney's license through The Missouri Bar's public directory, which shows active, good-standing status, and check separately with the Office of Chief Disciplinary Counsel for any public discipline. Ask how often the firm appears in the Jefferson County circuit court for cases like yours, since procedure there can differ from the courts of the city of St. Louis or St. Louis County. Put the fee arrangement — contingency, hourly or flat fee — in writing before any work begins.

Free and low-cost help

Legal aid programs serving Jefferson County provide free civil representation to income-eligible residents in housing, family and benefits matters. The regional bar association runs a lawyer referral service that offers a low-cost first consultation, and anyone facing criminal charges who cannot afford a lawyer may ask the court to appoint a public defender.
