By contracting to perform work or furnish materials on a project located in Wyoming, each contractor, subcontractor and materialman who asserts a lien submits to the laws of Wyoming and the jurisdiction of the district and circuit courts in the county in which the project is situated with respect to all lien claims, regardless of whether the lien claimant is a resident of Wyoming and regardless of whether the contract contains a contrary choice of law or venue provision. Venue for any mediation or arbitration of lien claims shall be proper only in the county in which the project is located, unless the parties agree otherwise.
