An Agreement to Assign is a legally binding document through which one party — the assignor — formally transfers their rights, benefits, or obligations under an existing contract to a third party known as the assignee. The agreement identifies the original contract being assigned, records any required consent from the counterparty (the obligor), defines precisely what is and is not being transferred, and allocates responsibility for pre- and post-assignment performance between the assignor and assignee. Unlike an informal notice of transfer, a properly executed Agreement to Assign creates an enforceable record that protects all parties and governs how disputes are resolved if the assignment is ever challenged.
Transferring a contractual position without a formal written agreement is one of the most preventable sources of post-transaction litigation in commercial practice. Without a signed Agreement to Assign, the obligor can refuse to recognize the transfer, the assignor may remain indefinitely liable for obligations they believed they had shed, and the assignee has no documented basis for asserting the rights they paid for. In business sales, restructurings, and real estate deals, an undocumented assignment can unravel entire transactions when the counterparty disputes the transfer or a court finds that required consent was never properly obtained. This template gives you a structured, professionally drafted starting point that captures all material terms — scope, consent, warranties, indemnification, and governing law — so that every party's position is unambiguous from the effective date forward.

Why it matters: Assigning a contract that prohibits assignment without consent renders the assignment void and places the assignor in breach of the original contract, potentially triggering termination rights in the obligor.
Fix: Review the original contract for assignment restrictions before drafting the agreement. Obtain the obligor's written consent and attach it as a schedule before either party signs.
Why it matters: Verbal or informal consent from the obligor is routinely disputed after the fact, leaving the assignee in a position that cannot be enforced and exposing the assignor to breach liability.
Fix: Use a formal written consent letter or Schedule A signed by the obligor before the assignment agreement is executed by the other parties.
Why it matters: Without a novation — a separate agreement signed by the obligor releasing the assignor — the assignor remains secondarily liable for performance if the assignee defaults. This surprise liability can be material in long-term contracts.
Fix: Either negotiate a novation with the obligor at the same time as the assignment, or include an express indemnification from the assignee covering any post-assignment liability the assignor incurs.
Why it matters: An undated assignment creates uncertainty about when the assignee's rights begin and when the assignor's obligations end — disputes over this gap are common in business sales and real estate transactions.
Fix: Always insert a specific calendar date or tie the effective date to a defined triggering event such as a transaction closing.
Why it matters: An assignment naming 'Acme Consulting' rather than 'Acme Consulting Inc.' may be unenforceable if the legal entity cannot be conclusively identified, particularly in cross-border or multi-entity group structures.
Fix: Confirm each party's full registered legal name, entity type, and jurisdiction before completing the parties clause.
Why it matters: A silent assignment — one that transfers rights without addressing obligations — leaves the obligor uncertain about who owes them performance and the assignor exposed to ongoing liability it believed it had shed.
Fix: Add an explicit assumption-of-obligations clause if the assignee is taking over performance duties, or a clear carve-out confirming only rights are assigned and the assignor retains all obligations.
In plain language: Identifies the assignor, assignee, and the original counterparty (obligor), and provides background context — the original contract being assigned and the commercial reason for the transfer.
This Agreement to Assign ('Agreement') is entered into as of [DATE] between [ASSIGNOR LEGAL NAME] ('Assignor') and [ASSIGNEE LEGAL NAME] ('Assignee'). The Assignor is a party to that certain [DESCRIPTION OF ORIGINAL CONTRACT] dated [ORIGINAL CONTRACT DATE] with [OBLIGOR LEGAL NAME] ('Original Contract').
Common mistake: Using trade names rather than registered legal entity names for any party. Enforcement against the wrong entity can fail at court, and the assignment may be void if the named party is not the actual contracting party.
In plain language: Defines precisely what is being assigned — whether the full contract, specific rights only, specific obligations, or a defined portion of the economic interest — and what is expressly excluded.
Assignor hereby assigns, transfers, and conveys to Assignee all of Assignor's right, title, and interest in and to the Original Contract, including all benefits, claims, and rights to receive payments thereunder, effective as of [EFFECTIVE DATE]. The following rights are expressly excluded from this assignment: [LIST EXCLUSIONS OR 'None'].
Common mistake: Assigning 'all rights' without reviewing the original contract for anti-assignment clauses. If the original contract requires consent and consent was not obtained, the assignment is void and the assignor may be in breach.
In plain language: States the value exchanged for the assignment — a cash payment, assumption of liabilities, an offset against a larger transaction, or nominal consideration where the assignment is part of a broader deal.
In consideration of [PAYMENT AMOUNT / the mutual covenants herein / the sum of $1 and other good and valuable consideration], the receipt and sufficiency of which are hereby acknowledged, Assignor agrees to assign the Original Contract as set out herein.
Common mistake: Omitting a consideration clause entirely on the assumption that the assignment is part of a larger deal. Courts require at least nominal consideration to enforce a stand-alone assignment agreement.
In plain language: Records whether the counterparty to the original contract has consented to the assignment and, if so, attaches or incorporates that consent as evidence.
The Obligor's written consent to this assignment is attached hereto as Schedule A and forms part of this Agreement. The Assignor represents that no other consent is required to effect a valid assignment of the Original Contract.
Common mistake: Proceeding with an assignment where the original contract requires consent without first obtaining it in writing. Verbal consent is rarely sufficient; an assignment without required written consent is typically voidable by the obligor.
In plain language: The assignor's factual statements confirming that the original contract is valid and enforceable, that the assignor has the authority to assign, that there are no existing defaults, and that no undisclosed encumbrances affect the assigned interest.
Assignor represents and warrants that: (a) the Original Contract is in full force and effect and has not been amended except as disclosed; (b) Assignor is not in default under the Original Contract; (c) Assignor has full authority to enter into this Agreement; and (d) the assigned interest is free and clear of any lien, pledge, or encumbrance.
Common mistake: Omitting the 'no default' representation. If the original contract is already in breach at the time of assignment, the assignee inherits a defective position and has no recourse without an express warranty.
In plain language: States whether the assignee is taking on the assignor's performance obligations under the original contract going forward, or whether only rights and benefits are being transferred.
Assignee hereby assumes and agrees to perform all obligations of Assignor under the Original Contract arising on or after the Effective Date. Assignee shall indemnify and hold harmless Assignor from any claims arising from Assignee's failure to perform such assumed obligations.
Common mistake: Failing to clearly distinguish between an assignment of rights only versus a full assumption of obligations. If the assignee does not expressly assume obligations, the assignor remains liable to the obligor for any post-assignment non-performance.
In plain language: Addresses whether the assignor retains any ongoing liability to the obligor after the effective date and whether the obligor releases the assignor from future performance obligations.
Unless the Obligor has executed a written novation releasing the Assignor from all future obligations, Assignor acknowledges that it may remain secondarily liable to the Obligor for performance of the Original Contract. Assignee agrees to perform all post-assignment obligations and to indemnify Assignor for any liability arising therefrom.
Common mistake: Assuming that executing an assignment agreement releases the assignor from the original contract. Without a novation signed by the obligor, the assignor typically remains liable if the assignee defaults.
In plain language: Each party agrees to compensate the other for losses arising from their own breaches — the assignor indemnifies for pre-assignment defaults; the assignee indemnifies for post-assignment failures.
Assignor shall indemnify Assignee against any claims, losses, or damages arising from any breach of the Original Contract prior to the Effective Date. Assignee shall indemnify Assignor against any claims arising from Assignee's non-performance of assumed obligations after the Effective Date.
Common mistake: Using a one-sided indemnification that only protects the assignee. If the assignor breached the original contract before the assignment, the assignee faces exposure it cannot recover without a matching indemnity.
In plain language: Specifies which jurisdiction's law governs the agreement and how disputes are handled — litigation, arbitration, or mediation — and in which venue.
This Agreement shall be governed by and construed in accordance with the laws of [STATE / PROVINCE / COUNTRY], without regard to its conflict-of-laws rules. Any dispute arising under this Agreement shall be resolved by [binding arbitration / litigation] in [CITY / COUNTY / JURISDICTION].
Common mistake: Selecting a governing law that differs from the governing law in the original contract. Conflicting governing law clauses can create ambiguity about which jurisdiction's rules apply to disputes involving the assigned rights.
In plain language: Confirms that the agreement (including any attached schedules) is the complete and final expression of the parties' understanding regarding the assignment, superseding any prior oral or written representations.
This Agreement, together with any schedules attached hereto, constitutes the entire agreement between the parties with respect to the assignment of the Original Contract and supersedes all prior negotiations, representations, and understandings. This Agreement may not be amended except by written instrument signed by both parties.
Common mistake: Omitting the entire-agreement clause when the assignment was negotiated informally over email. Without it, prior email threads and verbal commitments can be introduced as terms of the agreement in a dispute.
Enter the full registered legal name of the assignor, the assignee, and the obligor (the counterparty in the original contract). Include entity type — corporation, LLC, partnership — and jurisdiction of incorporation for each.
💡 Pull each entity name directly from your corporate registry filing or the original contract signature block. A mismatch voids enforcement.
Reference the original contract by its full title, execution date, and the parties to it. Attach a copy as a schedule if the obligor is also signing the assignment consent.
💡 If the original contract has been amended, list all amendments by date so the assignee takes the fully amended position, not just the base agreement.
Before completing the scope-of-assignment clause, locate any assignment restriction in the original contract. Determine whether consent is required, whether it can be withheld, and what form consent must take.
💡 Some contracts deem a change of control of the contracting party to be an assignment — review change-of-control definitions if this assignment follows a business sale.
Draft a short consent letter or complete Schedule A of the template, have the obligor execute it, and attach it to the agreement before the assignment is signed. File the signed consent with your transaction records.
💡 Get the obligor's consent before executing the main agreement — not after. An assignment signed before consent is received may be voidable even if consent arrives later.
Decide whether the assignee is taking on the assignor's performance obligations going forward or only receiving the benefits. State clearly what is included and what — if anything — is excluded.
💡 Lenders and investors typically want rights and economic benefits only. Buyers in a business acquisition typically assume all obligations. Mixing the two without clear language creates post-closing disputes.
Confirm the assignor's warranties are accurate as of the effective date — no defaults, no undisclosed encumbrances. Then split the indemnification cleanly: assignor covers pre-effective-date liabilities; assignee covers post-effective-date performance failures.
💡 If the assignor cannot honestly make the 'no default' warranty, disclose the known defaults in a schedule and carve them out of the warranty rather than omitting the warranty altogether.
Enter a specific calendar date on which the assignment takes effect. Both the assignor and assignee must sign before or on that date. Retroactive effective dates require careful drafting and are unenforceable in some jurisdictions.
💡 If the assignment is part of a larger transaction closing, tie the effective date to the closing date using a condition — 'effective upon the closing of [TRANSACTION]' — rather than a fixed calendar date.
Even when consent was obtained in advance, send a formal notice to the obligor confirming the effective date and providing the assignee's contact details for future correspondence and payments.
💡 In some jurisdictions, an assignment is not effective against the obligor until they receive written notice — sending notice is not a courtesy, it is a legal step.
An Agreement to Assign is a legal document through which one party — the assignor — transfers their rights, benefits, or obligations under an existing contract to a third party known as the assignee. It creates a binding record of the transfer, defines what is and is not being assigned, and allocates liability between the assignor and assignee for pre- and post-assignment performance. It is commonly used in business sales, commercial lease transfers, IP transactions, and loan assignments.
An assignment transfers rights and benefits from one party to another but does not automatically release the assignor from their obligations to the original counterparty. A novation goes further — it replaces the assignor entirely with the assignee as a contracting party, releasing the assignor from all future liability. Novation requires the consent and signature of the original counterparty; a simple assignment typically does not, unless the original contract requires it. If full release of the assignor is the goal, pursue a novation rather than a plain assignment.
It depends on what the original contract says. Many commercial contracts contain anti-assignment clauses requiring written consent from the counterparty before any assignment is valid. Assigning without required consent renders the assignment void and may constitute a breach of the original contract. Always review the original contract for assignment restrictions before proceeding, and obtain consent in writing if required.
Most contracts can be assigned unless the contract expressly prohibits it or the assignment would materially change the obligor's obligations — for example, personal services contracts where the identity of the performing party is fundamental. In most jurisdictions, the right to receive money (such as under a sales contract) is freely assignable even without consent, but the right to demand performance of a personal obligation may not be.
Unless the obligor has signed a novation releasing the assignor, the assignor typically remains secondarily liable for performance under the original contract. This means that if the assignee defaults, the obligor can still look to the assignor for damages. The assignment agreement should therefore include an indemnification clause obligating the assignee to cover any liability the assignor incurs as a result of the assignee's post-assignment non-performance.
The two terms are used interchangeably in most commercial contexts. An Agreement to Assign typically refers to a document formalizing an agreement to complete an assignment at a future date or upon a condition being satisfied, while an Assignment Agreement is the instrument that effects the transfer immediately. In practice, many templates — including this one — combine both functions in a single document with a defined effective date.
Notarization is not required for most commercial assignment agreements in common-law jurisdictions. However, assignments of real property interests or recorded documents — such as mortgages, deeds of trust, or patent registrations — may require notarization or registration with the relevant authority to be effective against third parties. Check the requirements of the specific asset type and jurisdiction before relying on an unnotarized document.
Some form of consideration is required to make an assignment agreement legally enforceable as a binding contract. In a business sale, the consideration is typically part of the purchase price. In a standalone assignment, it may be a specific payment, the assumption of obligations, or nominal consideration such as one dollar and mutual covenants. Including a consideration clause — even if the amount is nominal — is essential and should never be left blank.
For straightforward assignments of standard commercial contracts where the original contract permits assignment and no material obligations are changing hands, a well-structured template is a reasonable starting point. Legal review is strongly recommended when the original contract is complex, the assigned interest is high-value (real estate, IP portfolios, loan books), the assignment is part of a business acquisition, or the parties are in multiple jurisdictions with conflicting governing law.
A novation replaces the assignor as a contracting party entirely, releasing them from all future obligations with the obligor's consent. An Agreement to Assign transfers rights and may transfer obligations, but does not automatically release the assignor. Use a novation when the goal is a clean break; use an assignment when the assignor is willing to retain secondary liability or when the obligor's consent to a full release cannot be obtained.
A subcontractor agreement delegates specific performance obligations to a third party without transferring the original party's contractual position. The original party remains directly liable to the client. An Agreement to Assign transfers the contracting position itself. Use a subcontractor agreement when you want help delivering; use an assignment when you want to exit the contract entirely.
A Business Purchase Agreement governs the sale of an entire business including assets, liabilities, and contracts in bulk. An Agreement to Assign handles the transfer of a single specific contract or right. A business sale typically generates multiple individual assignment agreements as schedules to the main purchase agreement.
An Assignment of Lease is a specialized assignment document designed specifically for transferring commercial or residential lease obligations to a new tenant. It addresses landlord consent, lease terms, and security deposit handling in detail. Use the lease-specific template when assigning a tenancy; use the general Agreement to Assign for all other contract transfers.
Assignment of purchase contracts and commercial leases requires obligor consent in most jurisdictions and may trigger transfer tax or registration requirements.
Software licenses, SaaS agreements, and IP rights are frequently assigned in M&A and acqui-hire transactions; license agreements often include change-of-control provisions that function as anti-assignment clauses.
Loan assignments and receivables transfers are governed by UCC Article 9 in the US and require specific notice and perfection steps to be effective against the debtor and third-party creditors.
Service contracts with personal performance obligations — consulting, legal, or advisory — are often non-assignable without client consent; firm mergers and acquisitions require client-by-client consent processes.
Supply agreements and distribution contracts are routinely assigned in divestitures; obligors scrutinize assignee creditworthiness and operational capacity before consenting.
Provider agreements with insurers and government payers are subject to strict anti-assignment rules and credentialing requirements; assignment of a payer contract without prior approval typically voids the contract.
Under the UCC, assignments of rights under contracts for the sale of goods are generally permitted unless prohibited by agreement. Anti-assignment clauses in commercial contracts are enforceable. Assignments of security interests and receivables must be perfected under UCC Article 9 to have priority over third parties. California and New York have specific rules on the assignability of personal services contracts.
Assignment law in Canada is governed by common law in most provinces, with Quebec following civil law rules under the Civil Code. Assignments of contractual rights are generally valid unless prohibited by the contract or by statute. In Quebec, assignment of a claim requires notification to the debtor to be enforceable against them. Provincial consumer protection legislation may restrict assignment of consumer contracts.
Under English law, the benefit of a contract (rights) can generally be assigned without consent unless restricted. The burden (obligations) cannot be assigned without the obligor's agreement — only novation achieves a full transfer of obligations. An equitable assignment takes effect when notice is given to the obligor; a legal assignment under the Law of Property Act 1925 requires the assignment to be in writing and absolute. Scotland follows separate property law principles.
Assignment rules vary significantly across EU member states. Under German law, claims are freely assignable unless restricted by agreement or by the nature of the obligation. French law requires that assignments of receivables (cessions de créances) be notified to the debtor to bind them. GDPR applies where the assigned contract involves personal data processing, potentially requiring a new data processing agreement with the assignee.
