A Claim on Bond, also referred to a Notice of Nonpayment is a not a complicated process. The first step is to make sure that all your ducks are in a row.  If you are not contracted directly with the General Contractor, you are required to send a Notice to Owner/Notice to Contractor to secure your bond claim rights. The NTO must be received 45 days from first furnishing labor and/or material to the project.
The next step is to send the notice of nonpayment, also known as the claim on bond, to the General Contractor and the Surety. Now, just because you send the Notice of Nonpayment to the GC and the surety doesn’t guarantee that you are getting paid! That’s just one of the required steps. Most sureties are not going to just pay you because you sent a notice of nonpayment.
If you are still not paid after sending the notice of nonpayment you may want to consider hiring a construction attorney to file suit on the bond. You have 1 year from your last day of furnishing labor and/or materials to sue on the bond.
