About Two-Party AP Checks
Two-party (or joint checks) are generally used on to ensure payment to a supplier or vendor of by a particular subcontractor.
You can issue checks to two payees—the vendor and a second vendor or supplier to the vendor. For example, if you have not received a signed Waiver of Right To Lien form back from a subcontractor’s supplier, you can issue a two-party check to the subcontractor to ensure the supplier receives payment from the sub.
How you proceed depends on whether you are creating computer-generated checks or handwritten checks.
