In a contract, “successors and assigns” means the agreement binds not only the people or companies who signed it, but also anyone who later steps into their legal position. That includes a company formed by merger, the estate of a signer who dies, and any third party to whom one side transfers its rights. The clause usually lives in a “miscellaneous” or “general provisions” section and keeps the deal alive through ownership changes, corporate restructurings, and the death of a party.
Who Counts as a Successor
A successor is a person or entity that takes over another’s legal position, typically through something that happens automatically rather than by a deliberate handoff. In business, this most often arises in mergers and acquisitions. When one company absorbs another, the surviving entity steps into the acquired company’s contracts. That is why a well-drafted clause will refer to “any successor, whether by purchase, merger, consolidation, or otherwise.” The language prevents a company from shedding its obligations by restructuring itself out of existence.
For individuals, succession usually involves death. When someone who signed a contract dies, the executor or personal representative of the estate generally steps in to manage the outstanding obligations. Estate assets are used to pay debts and perform contractual commitments, and whatever remains passes to beneficiaries. The contract does not simply evaporate, although it may end if it was built around that person’s unique abilities.
Who Counts as an Assign
An assign (or assignee) is a third party who receives contractual rights through a voluntary, deliberate transfer. Where succession tends to happen by operation of law, assignment is a choice. One party decides to hand off a specific right — typically the right to receive a payment or a benefit — to someone who was not part of the original deal. The transfer is usually documented in a written assignment agreement that names the new recipient.
The default rule is that contractual rights are freely assignable. The Restatement (Second) of Contracts defines an assignment as “a manifestation of the assignor’s intention to transfer” a right, which extinguishes the assignor’s claim and gives the assignee a direct right to the obligor’s performance.1Restatement of the Law, Second, Contracts. Restatement Second of Contracts 317 – Assignment of a Right This happens constantly in commercial finance. A business sells its right to collect future payments to a bank or factoring company in exchange for immediate cash. The UCC provides a parallel framework for sales of goods, under which rights can generally be assigned and duties delegated unless the contract says otherwise.2Cornell Law Institute.

Why the Clause Is in the Contract at All
The clause exists because of a foundational idea called privity of contract. Under traditional rules, only the original signers can enforce the agreement or be held liable under it. The successors and assigns language extends that privity forward in time. Anyone who lawfully takes over a party’s position — by merger, inheritance, or assignment — inherits both the rights and the obligations as if they had signed the original deal.
Without the language, a party might argue that the contract died when the original company was acquired, or that a new owner has no duty to honor existing vendor agreements. The clause forecloses those arguments. It matters most in long-term arrangements like commercial leases, supply agreements, and loan documents, where the odds of an ownership change over the life of the deal are high.
How It Interacts With Anti-Assignment Clauses
Many contracts contain both a successors and assigns clause and a separate provision requiring written consent before either side can transfer its rights. These are not contradictory. The successors and assigns clause confirms the contract travels with the parties’ legal successors. The anti-assignment clause controls whether a party can voluntarily hand its position to a third party without the other side’s approval. You have to read them together to know what you can actually do.
What happens when someone assigns in violation of an anti-assignment clause is more nuanced than most people expect. Under the Restatement, a contractual prohibition on assignment generally does not make the assignment void. It gives the non-assigning party a right to sue for breach of the restriction, but the assignee still acquires rights against the assignor.3Restatement of the Law, Second, Contracts. Restatement Second of Contracts 322 – Contractual Prohibition of Assignment The UCC takes a similar line: a prohibition on assigning “the contract” is read as barring only the delegation of performance duties, not the transfer of rights.2Cornell Law Institute. Uniform Commercial Code 2-210 – Delegation of Performance; Assignment of Rights
Stronger language changes that result. If the contract states that any attempted assignment is “void” or “of no effect” rather than merely “prohibited,” courts are more likely to treat the transfer as a nullity. The difference between “you may not assign this contract” and “any assignment of this contract shall be void” can be the difference between a breach claim and a transfer that never legally happened.
Rights That Cannot Be Transferred
Not every contractual right survives a transfer, no matter what the successors and assigns clause says. The most common exception involves personal services, meaning agreements that depend on a specific person’s skill, judgment, or reputation. If you hire a particular architect to design your home, the architect cannot delegate that duty to a stranger. The Restatement frames this as a question of whether the other party has “a substantial interest in having that person perform or control the acts promised.”4Restatement of the Law, Second, Contracts. Restatement Second of Contracts 318 – Delegation of Performance of Duty If they do, the duty stays with the original party.
Outside personal services, an assignment also fails if it would materially change what the other side has to do, materially increase their risk, or materially reduce the value of the deal to them.1Restatement of the Law, Second, Contracts. Restatement Second of Contracts 317 – Assignment of a Right A classic illustration is a promise to support someone for life. The person receiving the support cannot assign that right to someone else, because the obligor’s burden might change dramatically depending on who they are now supporting.
Assignment Is Not an Exit
Readers often assume that assigning their rights lets them walk away from the contract. It does not. Assignment transfers benefits, but you remain on the hook for your obligations. If the assignee fails to perform, the other side can still come after you for breach. The Restatement is explicit: “neither delegation of performance nor a contract to assume the duty made with the obligor by the person delegated discharges any duty or liability of the delegating obligor.”4Restatement of the Law, Second, Contracts. Restatement Second of Contracts 318 – Delegation of Performance of Duty
The mechanism that does release you is a novation, which replaces the original contract with a new one that substitutes the incoming party for you. After a novation, the departing party has no remaining liability. Novation requires the consent of every party involved, however, so you cannot novate your way out without the other side agreeing.
How to Read the Clause in Your Own Contract
When you see language like “this agreement shall be binding upon and inure to the benefit of the parties and their respective successors and assigns,” do not read it in isolation. Look for separate provisions on assignment, change of control, or consent requirements. The successors and assigns clause alone will not tell you whether you can freely transfer your position; those other provisions will.
If you care about who performs under the contract — you chose a specific vendor, or you want control over who takes over a tenant’s lease — focus on whether the anti-assignment clause uses true voiding language. If you may need flexibility to sell your business or restructure, look for broad assignment rights or at least a standard that consent “shall not be unreasonably withheld.” The successors and assigns clause keeps the contract alive across ownership changes. The assignment restrictions control how much movement is actually permitted.
