A Montana subcontractor agreement is a written document outlining the terms of the business relationship between a contractor and a subcontractor. This relationship is not an employer-employee relationship, but an arrangement where the self-employed subcontractor agrees to perform services autonomously on a larger project for the contractor. The subcontractor is still obligated to complete their job in accordance with industry standards and to the satisfaction of the client who hired the contractor in the first place.

A subcontractor agreement includes key provisions of this working arrangement such as a list of services, who is responsible for labor and materials, the completion date of the services, and the amount of financial compensation. The contract also asserts that the subcontractor must have liability insurance and the necessary business licenses to work on the project.
