What do you do as a subcontractor if contractor doesnt pay?

If a contractor fails to pay, first review your contract to understand your rights and obligations. Attempt to resolve the issue through direct communication, documenting all correspondence. If the matter isn't resolved, consider sending a formal demand for payment and, if necessary, explore legal options such as filing a lien or pursuing mediation or arbitration, depending on your jurisdiction. Always consult with a legal professional for tailored advice.
