Pay When Paid vs Pay If Paid Clauses

One word separates two very different promises. A pay when paid clause says a subcontractor will be paid when the main contractor is paid by the owner, which is about timing. A pay if paid clause says the subcontractor will be paid only if the main contractor is paid, which is about risk. Under pay when paid, an owner's failure to pay usually delays the subcontractor's money; under an enforceable pay if paid clause, it can cancel it altogether.

These clauses are standard in construction subcontracts and increasingly appear in other multi-tier service work, such as agencies subcontracting to freelancers. This comparison explains how each works, where they are enforceable, example wording and how to protect your invoices. It is general information, not legal advice; enforceability depends heavily on jurisdiction and exact wording.

Pay when paid vs pay if paid at a glance

	Pay when paid	Pay if paid
What it controls	Timing of payment	Whether payment is owed at all
If the owner pays	Sub paid within the stated period	Sub paid within the stated period
If the owner pays late	Sub's payment delayed	Sub's payment delayed
If the owner never pays	Often still owed within a reasonable time	Potentially never owed, if enforceable
Who carries owner credit risk	Mainly the main contractor	The subcontractor
Key signal words	"within X days after receipt of payment"	"condition precedent", "only if", "assumes the risk"
Enforceability	Widely enforced as a timing term in the US	Varies; void in some US states and restricted in the UK

How a pay when paid clause works

A typical pay when paid clause reads something like:

"Contractor shall pay Subcontractor within seven (7) days after Contractor receives payment from Owner for the Subcontractor's work."

This sets a payment window tied to the owner's payment. In many US states, courts interpret this as a reasonable timing mechanism, not a transfer of the risk that the owner never pays. If the owner fails to pay, the contractor still has to pay the subcontractor within a reasonable time. What counts as "reasonable" depends on the facts and local law.

How a pay if paid clause works

A pay if paid clause is written to make the owner's payment a condition of the subcontractor's right to be paid:

"Receipt of payment by Contractor from Owner is a condition precedent to Contractor's obligation to pay Subcontractor. Subcontractor expressly assumes the risk of Owner's non-payment."

Courts that enforce these clauses usually require the language to be clear and unambiguous, because the effect is harsh: the subcontractor may do the work and never be paid if the owner defaults. Words like "condition precedent" and an express assumption of risk are what normally distinguish pay if paid from pay when paid.

Where the clauses are enforceable

United States

There is no single national rule; it is a state-by-state question.

• California: In Wm. R. Clarke Corp. v. Safeco Insurance Co. (1997), the California Supreme Court held pay if paid clauses unenforceable as contrary to public policy, because they effectively waive subcontractors' mechanics' lien rights. Pay when paid clauses that simply set a reasonable time for payment were not addressed by that ruling.
• New York: In West-Fair Electric Contractors v. Aetna Casualty & Surety (1995), New York's highest court also refused to enforce a pay if paid clause on public policy grounds.
• Other states: Several states enforce clearly drafted pay if paid clauses, others restrict them by statute or case law, and some limit them on public projects. Check the law of the state where the project is located and the law named in your contract.

Separately, federal and state prompt payment rules set deadlines for paying contractors on public projects; see our guide to the Prompt Payment Act.

United Kingdom

For construction contracts, section 113 of the Housing Grants, Construction and Regeneration Act 1996 provides that a clause making payment conditional on the payer receiving payment from a third person is ineffective, unless that third person (or a party further up the chain) is insolvent. In practice, both pay when paid and pay if paid clauses are largely ineffective in UK construction contracts covered by the Act, apart from the insolvency exception. UK subcontractors may also need to deal with the Construction Industry Scheme; our CIS invoice template covers the deductions.

Worked example

A drywall subcontractor completes $48,000 of work and invoices the main contractor on 1 March. The owner disputes the main contractor's unrelated electrical work and withholds the entire payment application.

Scenario	Subcontract wording	Likely outcome for the $48,000
A	Pay within 10 days of contractor's receipt of owner payment	Delayed, but in many US states due within a reasonable time even if the owner never pays
B	Owner payment is a condition precedent; sub assumes risk of non-payment	In a state that enforces pay if paid, may not be owed until the owner pays; in California or New York, likely unenforceable
C	Same as B, but the project is in England under the 1996 Act	Condition is ineffective unless the owner is insolvent; the Act's payment provisions apply

Retention complicates this further. If 5% retainage is held ($48,000 x 0.05 = $2,400), the release of that $2,400 may be tied to project completion, adding more delay. Our guide to retainage invoices shows how to bill and track retention separately.

How subcontractors can protect themselves

1. Read the payment clause before signing. Look for "condition precedent", "if and only if" and "assumes the risk".
2. Negotiate the wording. Ask to replace pay if paid with pay when paid, add a long-stop date (for example, "in any event no later than 45 days after the subcontractor's invoice"), or limit the condition to owner insolvency only.
3. Exclude contractor-caused non-payment. If the owner withholds because of the main contractor's defective work, the subcontractor should not bear that risk.
4. Protect lien and bond rights. Preliminary notice and lien deadlines run regardless of the subcontract. Our guides to mechanics' liens and lien waivers explain the steps, including not signing unconditional waivers before you are paid.
5. Invoice precisely. Match your invoice to the contractor's pay application cycle, reference the subcontract, show work completed to date (measured against the bill of quantities where there is one), retention held and the amount due. A clear subcontractor invoice template helps.
6. Document completion. A signed work completion certificate makes it harder to argue the work was not done.
7. Ask about the owner's funding. Is there a construction loan or payment bond? Who is the owner? Knowing this tells you how real the risk is.

What main contractors should consider

• Draft for the right jurisdiction. A pay if paid clause copied from a template used elsewhere may be void where your project is.
• Be specific. Ambiguous language is usually read against the party who wrote it and in favour of treating it as pay when paid.
• Keep subcontractors informed. Sharing the status of owner payments reduces disputes and liens.
• Do not withhold for unrelated reasons. Using a pay when paid clause to hold payment for a sub's completed, approved work because of a dispute about someone else's work invites claims.

Common mistakes

• Assuming the clause means the same everywhere. It does not; local law decides.
• Signing unconditional lien waivers early. These can give away your security before you are paid.
• Missing notice deadlines while waiting for the owner to pay.
• Vague invoices. If your invoice does not tie clearly to the pay application, it is easy for it to be left out.

Beyond construction: agencies and freelancers

Similar clauses appear outside building projects. A marketing agency hiring a freelance designer for a client campaign may write "payment will be made within 14 days of the agency receiving payment from the client". That is a pay when paid clause in substance. A stricter version, "the freelancer will be paid only if and when the client pays the agency", attempts to shift the end client's credit risk onto the freelancer.

Freelancers can respond the same way subcontractors do: ask for a long-stop date, such as payment within 45 days of invoice regardless of whether the end client has paid, or for a fixed payment date with no condition. Some freelancer protection laws, such as New York State's Freelance Isn't Free Act, require payment by the contract date or within 30 days of completion where no date is set, which may affect how such clauses operate for covered work.

Questions to ask before you sign

• Does the clause set a time, or does it make payment conditional?
• Is there a long-stop date after which payment is due regardless?
• Does the condition apply if the owner withholds because of someone else's work?
• Which law governs the contract, and is that where the project is located?
• Is there a payment bond, and what are the notice deadlines?
• How is retention released, and is that release also conditional?
