What Does “Enure” Mean in a Contract?
Enure (also spelled “inure”) means “to take effect” or “to come into operation for the benefit of.” When a contract states that it “shall enure to the benefit of” the parties and their successors, it means the contract’s rights and obligations extend beyond the original parties — binding and benefiting their successors, assigns, heirs, or other specified beneficiaries.
You’ll almost always see this term in the “successors and assigns” clause near the end of a contract. Despite being boilerplate, what this clause actually does deserves careful attention — especially for Illinois startups navigating acquisitions, assignments, and co-founder departures.
The Standard Successors and Assigns Clause
A typical version reads:
“This Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective heirs, executors, administrators, legal representatives, successors, and assigns.”
Breaking this down:
- “Binding upon” — the obligations of the contract follow the party, not just the individual who signed
- “Inure to the benefit of” — the rights under the contract also transfer to successors
- “Successors” — entities that take over a party’s business through merger, acquisition, or reorganization
- “Assigns” — parties to whom rights have been assigned with consent (or without, if the agreement permits it)
Why This Clause Matters for Startups
Acquisitions
When your startup is acquired, the acquirer wants to know that your contracts — customer agreements, vendor contracts, IP licenses — will transfer with the business and be enforceable by them. The enurement clause is what makes that possible. Without it, a strict reading might allow the counterparty to argue that the contract only benefits the original signatories.
Operator and Founder Changes
If a co-founder leaves the company and the remaining founders want to enforce provisions of the founders’ agreement — vesting provisions, non-solicitation clauses, IP assignments — the enurement clause ensures the company (as an entity) can enforce those rights, not just the individual who signed.
SaaS Customer Agreements
When a customer who signed your SaaS agreement is itself acquired, does the acquirer inherit the license? The answer depends partly on the enurement clause and partly on anti-assignment language. If the agreement permits assignment to successors and explicitly enures to their benefit, the acquirer gets the license. If not — or if the license is personal and non-transferable — the license terminates.
Enure to the Benefit of vs. Third-Party Beneficiaries
The enurement clause shouldn’t be confused with third-party beneficiary rights. A third-party beneficiary is an outside party who can enforce a contract even though they didn’t sign it — because the contract was intended to benefit them directly. The enurement clause, by contrast, extends rights to parties who stand in the shoes of the original contracting parties — successors and assigns — not independent outsiders.
When the Clause Can Work Against You
The same enurement that protects you in an acquisition can create problems if you’re on the other side:
- A vendor whose contract enures to successors can be acquired by a competitor — and now your competitor has access to your confidential information or IP through the acquired vendor’s agreement
- A non-compete that enures to the benefit of the company can be enforced by an acquirer you never dealt with
- Obligations that enure to successors mean that when you sell your company, the buyer inherits all your contractual commitments — including ones you’ve forgotten about
Before any acquisition — as buyer or seller — it’s essential to inventory all material contracts and understand which ones enure to successors. Fitter Law assists with contract review for Chicago businesses, including pre-transaction due diligence. View our subscription plans.
Frequently Asked Questions
Is “enure” the same as “inure”?
Yes. Both spellings are correct and used interchangeably in legal drafting. “Inure” is more common in American legal documents; “enure” appears more frequently in British-influenced drafting. If you see either spelling in a contract, they mean the same thing.
Can I prevent a contract from enuring to an acquirer’s benefit?
Yes, with careful drafting. An anti-assignment clause that prohibits transfer without consent — combined with language specifying that the contract is personal to the original party — can prevent automatic enurement to an acquirer. Whether that’s what you want depends on your commercial goals.
Does a contract that enures to successors survive the death of a sole proprietor?
In theory, yes — obligations and rights pass to the estate and personal representative. But in practice, many service contracts are personal to the individual and not assignable as a matter of contract law or practical reality. A professional services agreement with a sole practitioner generally terminates at their death regardless of the enurement clause.
