Contract assignment when selling a business

Review assignment and novation when selling a business, including consent, continuing obligations and change of control provisions.

Jurisdiction: England and Wales.

A business sale does not automatically transfer every contract to the buyer. Assignment and novation have different functions, and the required route depends on the rights and obligations involved. Review each important agreement against the proposed sale structure before promising a seamless transfer.

In an asset sale, identify which contractual benefits and obligations need to move. In a share sale, the contracting company may remain the same, but a change of control clause can still matter. Check guarantees and releases separately so the seller understands any continuing exposure.

Start with the sale structure and contracting parties

Identify whether the transaction transfers shares in a company or selected business assets. In a share sale, the same company may remain party to its contracts, while change-of-control provisions can still require attention. In an asset sale, the buyer is a different contracting person and the movement of rights and obligations needs specific analysis.

Use company numbers and legal names in the contract schedule. Shared branding can conceal different group entities or a contract held personally by a founder. Confirm the actual party before promising transfer. A business-sale description listing all customer relationships does not establish that the seller owns or can transfer each one.

Distinguish benefits from obligations

Assignment and novation have different legal functions. Identify what must move and whether the proposed route transfers the required obligations as well as rights. Obtain advice on the relevant wording and consent process rather than assuming an assignment clause creates a complete substitution of the buyer for the seller.

Read restrictions carefully, including consent standards, notice requirements and exceptions for group transfers. A provision permitting assignment to an affiliate may not cover a sale to an unrelated buyer. Check whether a later move outside the group triggers additional conditions. The transaction plan should use the actual clause, not a general expectation that business contracts are transferable.

Prioritise consents that affect continuity

Rank contracts by revenue, operational dependency and difficulty of replacement. Seek necessary consents early enough to address questions or refusal. A key customer or software provider may require information about the buyer before agreeing. Do not leave a critical consent until the final day while presenting it as a routine administrative step.

Record requested, agreed and completed statuses separately. A counterparty saying it is comfortable in principle may not have given the formal consent or executed the document required. Keep the conditions and expiry of any consent visible so the completion team can verify that it covers the actual transaction and date.

Allocate historic liabilities and continuing exposure

The buyer and seller may agree between themselves who bears earlier claims, but that allocation does not necessarily bind the counterparty. Review guarantees, deposits, accrued fees and unresolved disputes separately. A seller can remain exposed unless the relevant party gives an effective release. Obtain documentary evidence rather than relying on the sale agreement's broad allocation alone.

Check any security or personal guarantees connected with the contract. If replacement security is required, coordinate it with the transfer. A buyer's promise to indemnify the seller is a separate protection and may depend on the buyer's ability to pay. It should not be described as equivalent to release by the original beneficiary.

Connect legal transfer with operational handover

Identify customer notices, billing details, data access, licences and service responsibilities from the effective date. A valid transfer document does not automatically update systems or tell customers where to send instructions. Plan the handover so payments and performance are attributed to the correct entity during the transition.

Employee transfer questions can arise separately under TUPE where its conditions are met. GOV.UK guidance explains that business transfers can affect employment responsibilities. [1] Do not assume that assigning a commercial contract resolves staffing obligations, consultation or the treatment of employees involved in delivering the service.

Complete and preserve the transfer evidence

Check authority, signatures and any relevant company execution formalities for the transfer documents. [2] Retain consents, notices and the final contract schedule with the sale record. Confirm which agreements did not transfer and the agreed response for each unresolved item.

Read Selling a business with registered IP where registered IP is part of the sale. Commercial contract review can help review assignment, novation and change-of-control provisions against the transaction structure, with employment and other specialist issues addressed separately where required.

Reconcile the final consent list at completion

Compare the executed transaction with each consent obtained. A consent for a named buyer or a particular asset package may not cover a changed structure. Identify any mismatch before completion and obtain the required clarification. Keep contracts remaining with the seller visible, with a lawful operational arrangement for any interim service rather than assuming an incomplete transfer has already occurred.

Illustrative scenario

A buyer expects to take over a maintenance contract in an asset purchase. The contract restricts transfer without customer consent. The parties add the consent to their completion plan and consider the consequences of refusal. A schedule simply listing the contract would not establish that the transfer is effective.

Preparation checklist

  • Identify the transaction structure and contracting entities.
  • Check assignment, novation and change of control wording.
  • Record required consents and any continuing guarantees.
  • Align the effective transfer date with operational handover.

Frequently asked questions

Does an asset sale automatically transfer all customer contracts?

No. Review the relevant rights, obligations, restrictions and consents. Listing a contract in the sale schedule does not by itself complete an effective transfer.

Are assignment and novation interchangeable?

No. They have different functions. Identify what must move and obtain advice on the route required for the particular rights, obligations and parties.

Can a share sale still trigger a contract clause?

Yes. Although the contracting company may remain the same, a change-of-control or related provision can require consent, notice or another response.

Does the buyer's indemnity release the seller from the customer?

Not necessarily. An allocation between buyer and seller may not bind the customer or guaranty beneficiary. Check whether a separate effective release is required.
