If you engage in a transaction or business with someone or a company that is outside Missouri, but you are located in Missouri, and the transaction goes awry, you are able to sue that person or company in Missouri. Missouri states that a Missouri court has jurisdiction over a person or company if they have connections with the state that are systematic, continuous and substantial. Missouri has held that transacting business online with Missouri residents is enough for Missouri courts to have jurisdiction over that person doing business with Missouri residents. If you have been wronged by a person or business out of Missouri, contact our law office at 816-524-4949 or www.Hoorfarlaw.com.
