Payment Claim Guidance

Construction payment disputes often involve more than a late invoice. The contract may define conditions for progress payments, retainage, approved changes, notices and permitted deductions. Different parties may disagree about whether the work was finished or adequately documented.
AW Construction Law addresses payment-related legal concerns in the context of construction contracts, change orders and subcontractor disputes. The next step depends on the actual agreement, project record and applicable law.
