What concept does a forum selection clause typically involve?

A forum selection clause typically involves a limitation of the venues where a lawsuit may be filed. This type of clause specifies the particular location or court in which any disputes related to the agreement must be resolved. It is an important aspect of contract law, as it provides clarity and predictability for the parties involved, allowing them to understand in advance where legal actions will be conducted.

The other options, while related to jurisdictional issues, don't accurately reflect the primary function of a forum selection clause. Option A, a specification of substantive law, pertains to which laws will govern the disputes but does not determine where they will be litigated. Option C, a requirement for arbitration, concerns alternative dispute resolution rather than the choice of venue for litigation. Option D, a waiver of jurisdictional challenges, speaks to the right to contest personal jurisdiction but is not the main purpose of a forum selection clause. The focus on venue limitation is what fundamentally characterizes a forum selection clause, making the provided answer correct.
