It’s unlikely that a ProductLink code="NONCOM" text="Non-Compete Agreement" will be enforceable as part of an Independent Contractor Agreement.
Non-compete clauses are designed to prevent executive level employees or former partners from gaining an unfair competitive advantage against their former employer by using information gained through working in that business. However, it’s in the nature of independent contractors to seek work with different clients.
An enforceable Non-Compete Agreement needs to be reasonable in time, space, and scope. Putting any restrictions on an independent contractor's ability to find work will likely be deemed unreasonable.
