Assignment and Assumption Agreement Template

Contracts do not always stay with the people who signed them. A business gets sold, a tenant moves out mid-lease, a lender offloads a loan, or a franchisee hands the store to a new owner. In each case, someone needs to step out of an existing contract and someone else needs to step in. The document that makes that switch clean is an assignment and assumption agreement.

Get it wrong and you can end up transferring the benefits of a contract while staying personally on the hook for its debts, or you assign something the contract never allowed you to assign in the first place. This guide walks through what the agreement does, when you need the other side's consent, how it differs from a novation, and how to draft one that actually shifts the risk you think it shifts.

What Is an Assignment and Assumption Agreement?

An assignment and assumption agreement is a contract that transfers one party's rights and obligations under an existing agreement to a new party. It has two moving parts working together:

• Assignment hands over the rights and benefits, the right to collect payment, receive goods, or enforce the contract.
• Assumption transfers the duties, the new party's promise to perform the obligations the original party owed.

The party giving up the contract is the assignor. The party taking it on is the assignee. The other side of the original contract, the one who is not changing, is usually called the counterparty or obligor.

A plain assignment moves only the benefits. Pairing it with an assumption is what makes the assignee responsible for holding up the deal going forward. That combination is why this document shows up constantly in business sales, real estate, and lending.

Assignment vs. Assumption vs. Novation

These three terms get used loosely, and the difference decides who is liable when something goes wrong.

Assignment transfers rights. On its own, it says nothing about who performs the duties.

Assumption is the assignee's agreement to take on the duties. Assignment plus assumption gives you a full handoff of both sides of the ledger.

Novation goes one step further. It cancels the original contract and replaces it with a new one between the counterparty and the assignee, releasing the assignor entirely. A novation always needs the counterparty's signature because you are rewriting who they are dealing with.

A quick example makes the difference concrete. Say a caterer assigns its contract with a wedding venue to another caterer and the new one botches the event. Under a plain assignment and assumption, the venue may still be able to sue the original caterer, because assumption made the newcomer liable but never let the first caterer off the hook. Under a novation, the original caterer is gone from the picture and the venue's only target is the replacement.

Here is the trap: an assignment and assumption agreement, by default, does not release the assignor. If the assignee later fails to pay, the counterparty can often still chase the original party. If a clean exit is what you are after, you either need a release baked into the agreement or you need to structure the whole thing as a novation. For a deeper look at that mechanism, see our guide on the novation agreement.

When You Need One

An assignment and assumption agreement earns its keep in a handful of recurring situations:

• Business and asset sales. When a buyer acquires a business through an asset purchase, they rarely want the whole company. They pick specific contracts, vendor agreements, and permits and take them over through assignment and assumption rather than renegotiating each from scratch. This pairs naturally with a business purchase agreement.
• Commercial lease transfers. A tenant leaving before the term ends can assign the lease to a replacement tenant who assumes the rent and other obligations. Landlords almost always require consent here. Assigning is different from subletting, and the distinction changes who stays liable, which we break down in lease amendments: subleasing vs. assigning.
• Loan and receivables transfers. Lenders sell loans and portfolios of receivables to other institutions, moving both the right to collect and the servicing duties.
• Franchise resales and vendor changes. An outgoing franchisee or a supplier being replaced passes its contract to the incoming party.

The common thread: an existing contract has value, and rather than tear it up, the parties want to move it to someone new.

Can You Even Assign It? Read the Anti-Assignment Clause First

Before drafting anything, open the contract you plan to transfer and find its assignment clause. This single provision decides whether your deal is possible.

Contracts fall into three camps:

1. Freely assignable. The contract is silent or expressly allows assignment. You can proceed, though notice to the counterparty is still good practice.
2. Assignable with consent. The most common setup. The contract permits assignment only with the counterparty's prior written consent, often with a line saying consent "shall not be unreasonably withheld." You must secure that consent before or at closing.
3. Non-assignable. Some contracts flatly prohibit transfer, and a few go further, stating that any attempted assignment is void. Assigning in the face of that language can breach the contract and hand the counterparty a right to terminate.

Two more limits apply even when the contract says nothing. Duties that depend on someone's personal skill, judgment, or reputation generally cannot be delegated without consent; you cannot assign your obligation to paint a portrait to a stranger. And an assignment that materially increases the counterparty's risk or burden may be blocked regardless of the clause.

Skipping this step is the single most common way these deals fall apart. An assignment the underlying contract never permitted is worth little.

Key Clauses in an Assignment and Assumption Agreement

Once you have confirmed the transfer is allowed, the agreement itself should cover the following.

1. Identification of the Underlying Contract

Name the contract being transferred with precision: its title, its effective date, and the original parties. Attach a copy as an exhibit if you can. Vague references like "the services agreement" invite disputes over exactly what moved.

2. Assignment of Rights

State clearly that the assignor transfers all of its rights, title, and interest in the underlying contract to the assignee, effective on a specified date. If only part of the contract is being assigned, spell out exactly which rights.

3. Assumption of Obligations

State that the assignee accepts and agrees to perform all obligations under the contract arising on or after the effective date. Draw a clean line on timing. A well-drafted agreement makes clear whether the assignee is taking on only future obligations or also liabilities that accrued before the transfer. Buyers usually want the former; sellers sometimes push for the latter.

4. Consent of the Counterparty

If the underlying contract requires consent, capture it. Either have the counterparty sign the agreement itself or attach a separate signed consent. Without this, an assignment that needed consent may be ineffective or a breach.

5. Release (Optional but Important)

This is the clause people forget. If the assignor wants out for good, add a release in which the counterparty discharges the assignor from future obligations. No release means the assignor likely stays secondarily liable. Decide this deliberately rather than by accident.

6. Representations and Warranties

The assignor typically warrants that the contract is valid and in force, that it has not already assigned or pledged the contract elsewhere, that it is not in default, and that no consent beyond what is being obtained is required. These promises give the assignee something to sue on if the picture turns out to be false.

7. Indemnification

Allocate responsibility for what came before and what comes after. The assignor commonly indemnifies the assignee for claims tied to the period before the transfer; the assignee indemnifies the assignor for claims arising after it. Getting this split right is where a lot of the real money sits, and it works best alongside a dedicated indemnification agreement or clause.

8. Governing Law and Signatures

Name the state whose law controls and where disputes are resolved. All necessary parties sign: assignor, assignee, and the counterparty where consent or a release is involved. For entities, confirm the signer has authority to bind the company.

How to Write One: Step by Step

Step 1: Read the underlying contract's assignment clause. Confirm the transfer is permitted and note whether consent is required. Everything else depends on this.

Step 2: Identify the parties and the contract. Use full legal names, entity types, and the exact title and date of the contract being transferred.

Step 3: Draft the assignment. State that the assignor transfers all rights and interest as of the effective date, and specify whether it is a full or partial assignment.

Step 4: Draft the assumption. Have the assignee expressly accept the duties and fix the cutoff date for which obligations it is taking on.

Step 5: Secure consent. If the contract requires it, get the counterparty's written consent, ideally on the agreement itself.

Step 6: Decide on a release. If the assignor wants a clean break, negotiate a release from the counterparty. If not, understand that the assignor stays on the hook.

Step 7: Add warranties, indemnity, governing law, and signatures. Close out the risk allocation and execute.

Common Mistakes to Avoid

Assuming the contract is assignable. The anti-assignment clause is the first thing to check, not the last. Deals collapse when someone signs an assignment the underlying contract prohibited.

Confusing assumption with release. Assumption makes the assignee liable. It does not make the assignor un-liable. Those are two separate things, and only a release accomplishes the second.

Leaving the accrual date vague. "The assignee assumes the obligations" without a date is an argument waiting to happen over who owns a liability that arose the week before closing.

Forgetting counterparty consent. An assignment that required consent and did not get it can be void or a breach, unwinding the whole transaction.

Skipping warranties. Without the assignor promising the contract is valid and in good standing, the assignee inherits hidden defaults with no recourse.

Ignoring related duties. A contract being assigned often ties into loans, guarantees, or security interests. Transferring it may trigger obligations elsewhere, so check whether the deal interacts with financing like a loan agreement before signing.

A Quick Word on Real Estate and Regulated Contracts

Interests in real property and certain regulated contracts carry extra formalities. Some require recording, notarization, or specific statutory language, and some lenders demand their own consent before a borrower can assign a related agreement. When property, government permits, or licensed activity is involved, confirm the local rules rather than relying on a generic template.
