Pay-When-Paid vs. Pay-If-Paid

Understanding Your Contract Terms

Pay-When-Paid:

  • Common clause
  • You must pay sub within reasonable time after you're paid
  • Sets timing, but sub is eventually entitled to payment

Pay-If-Paid:

  • More restrictive
  • Your payment to sub is conditioned on you being paid
  • May not be enforceable in all jurisdictions
  • Consult legal counsel

Best Practice

  • Pay subs promptly regardless of owner payment
  • Maintain good relationships
  • Sub payment delays create lien exposure
