What Is a No-Waiver Clause in a Contract?

A no-waiver clause says that if a party does not enforce a right straight away, for example by accepting a late payment once, it has not given up that right and can still enforce the same term later. It may also require any real waiver to be in writing and signed.

Why it matters

Past flexibility is not a promise for the future. A deadline the other side let slide once can be enforced strictly the next time.

How common is it?

In the LexGLUE version of LEDGAR, a research set of 80,000 contract provisions from SEC filings, each labelled with one of 100 common provision types, 604 (0.76%) are labelled "No Waivers". That is a share of provisions, not of contracts. It is the 48th most common of the 100 provision types in this set.

These are provisions from contracts that public companies filed with the SEC — a reference point, not a rule for your contract.

What to watch for

  • Relying on repeated informal flexibility, such as late payments being accepted.
  • A one-way clause that protects only the other side.
  • Waivers required in writing while day-to-day changes happen by phone.

A realistic example

A client accepts a freelancer's deliveries a few days late for months. After a dispute, it enforces the delivery deadline strictly and claims a late-delivery fee.

What to ask for

  1. Any agreed flexibility, such as a grace period, written into the contract.
  2. The same no-waiver protection for both sides.
