Deed of Assignment and Assumption Template (UK)
Updated on 9 August 2026
A UK assignment and assumption agreement transfers rights and, where consent is obtained, may sit beside a novation that substitutes a new party to a contract. The distinction is not academic. English law generally allows assignment of contractual benefits, but liabilities are not simply assigned away. A party that wants to be released from obligations usually needs novation with the consent of all parties.
The source template uses US-style "assignment and assumption" language without explaining that UK liabilities normally need novation, that legal assignments of debts and other legal things in action have statutory requirements under the Law of Property Act 1925, and that notices and counterparty consents are often the real completion deliverables. This UK template makes the mechanism explicit.

Assignment transfers benefit, not every burden
An assignment can transfer the benefit of a contract, debt or right to receive payment. It does not by itself make the assignee liable to perform the assignor obligations, and it does not automatically release the assignor. That is why a buyer of a contract portfolio usually needs to check whether each contract permits assignment, prohibits it or requires consent.
The template asks whether the transaction is a rights-only assignment, an assignment with a separate assumption covenant between assignor and assignee, or a three-party novation. That prevents the document from promising more legal effect than the mechanism can deliver.
Legal assignment and notice
Section 136 of the Law of Property Act 1925 provides a route for legal assignment of certain debts and legal things in action where the assignment is absolute, in writing under the hand of the assignor and express written notice is given to the debtor, trustee or other relevant person. If those conditions are not met, the assignment may still be equitable, but enforcement and notice mechanics differ.
For practical drafting, the notice can matter as much as the transfer clause. The template includes a notice schedule showing who must receive notice, how it will be served, when it is effective and what evidence will be retained.
Novation needs all-party consent
HMRC manuals summarise the basic legal distinction: benefits can be assigned, but liabilities cannot generally be assigned; novation is the process by which all parties agree to substitute a new party and discharge the old one. That is the concept many "assumption" templates hide behind a signature block.
If the counterparty must release the assignor, use a novation deed or a three-party assignment and novation agreement. If the counterparty is not signing, the assignee may promise the assignor that it will perform, but the original counterparty may still be able to pursue the assignor unless the underlying contract and law provide otherwise.
Public contracts, regulated contracts and anti-assignment clauses
Some contracts restrict assignment, require prior written consent, or treat assignment as a default. Public contracts can also raise procurement-law modification questions where a supplier changes through restructuring, sale or novation. Regulated financial, insurance, employment, property, IP and data-heavy contracts can need specialist steps.
The template therefore includes consent conditions, warranties about restrictions, a no-conflict confirmation and a schedule of excluded rights. It does not let the parties tick "all contracts" and move on.
Completion deliverables and warranties
A useful deed identifies the assigned rights, effective time, consideration, notices, consents, documents, records, warranties and indemnities. The assignor should warrant title to the rights, absence of undisclosed restrictions and accuracy of information. The assignee should covenant to perform assumed obligations and reimburse the assignor where appropriate.
Completion should produce executed deeds, notices, consent letters, updated payment instructions, data-transfer records and any third-party filings. Without those deliverables, the parties may have a document but no operational transfer.

Check these points before relying on an assignment or assumption document.
Do not assign liabilities by wording alone
Liabilities generally cannot simply be assigned. A release and substitution normally needs novation with all-party consent.
HMRC CTM61605 - assignment and novationCheck statutory legal-assignment requirements
For certain legal assignments, Law of Property Act 1925 section 136 requires an absolute written assignment and express written notice to the relevant debtor or other person.
Law of Property Act 1925 section 136Review the underlying contract
Anti-assignment clauses, consent requirements, change-of-control clauses, confidentiality, data-transfer and notice provisions can block or condition the transfer.
Use novation when the outgoing party needs release
Novation substitutes a new contract or party with the consent of all parties and is usually needed for full liability transfer.

Public-sector contracts can raise procurement-law modification rules where contract transfer follows restructuring, sale or novation.

Keep evidence of notices to debtors, counterparties, trustees, agents and payment processors.
Check IP and data transfers
Copyright assignments need signed writing, and personal data transfers need a lawful basis and security measures.

How to complete the deed
- Choose the mechanism. Decide whether this is assignment, assignment plus assumption covenant, or novation with counterparty consent.
- List rights and exclusions. Identify assigned rights, excluded rights, contracts, debts, receivables, IP and records.
- Check consents. Review contracts for anti-assignment clauses, notices, releases and novation signatures.
- Draft notices. Prepare notices to counterparties, debtors, trustees or other required recipients.
- Complete and retain evidence. Sign the deed, deliver notices, update payment instructions and keep consent and delivery evidence.
Frequently asked questions
What is the UK difference between assignment and novation?
Assignment transfers rights or benefits. Novation substitutes a party or contract with all-party consent and is normally needed to transfer liabilities and release the outgoing party.
Can I assign a contract without the other party signing?
Sometimes you can assign the benefit if the contract allows it, but you usually cannot transfer the burden or obtain release without the counterparty consent.
What is a legal assignment under the Law of Property Act 1925?
For certain debts and legal things in action, section 136 requires an absolute written assignment and express written notice to the relevant debtor or other person.
Does an assumption clause bind the original counterparty?
Not by itself. It can create a promise between assignor and assignee, but the original counterparty may still need to consent for release or full substitution.
When should I use a deed?
A deed is often used where consideration is uncertain, where the underlying document requires a deed, or where the parties want formal execution evidence.
Can public contracts be assigned or novated?
They can raise procurement-law modification issues and consent requirements. Check the contract and the applicable public procurement rules before relying on a transfer.
What notices should be sent?
Send notices required by the contract and, where legal assignment treatment is sought, notice to the debtor or relevant person. Keep evidence of delivery.
