A. The issue you raise concerning withholding payment of a supplier's invoices to offset the supplier's debt to you is outside the regulatory authority of the FTA. In the absence of a contract clause addressing this issue, the matter would be governed by State law. Each state’s laws differ regarding withholding or deducting funds for claims owed on unrelated/separate contracts. You should contact an attorney in your state that can help you with this problem.
