When a debt changes hands, the transaction is captured in a single key document: the deed of assignment. Get it right and the buyer can enforce the debt cleanly; get it wrong and you can create months of legal difficulty. Here is what this document does and what it should contain.
What is a deed of assignment?
A deed of assignment is the written agreement by which the original creditor (the assignor) transfers ownership of a debt to a buyer (the assignee). It is the document that satisfies the requirements of section 136 of the Law of Property Act 1925 for a legal assignment: it must be in writing, signed by the assignor, absolute (not by way of charge only), and it triggers the need to give written notice to the debtor.
Why use a deed rather than a simple contract?
An assignment can be made by simple agreement, but executing it as a deed avoids arguments about whether the buyer gave something of value (consideration), and provides a longer limitation period for claims on the document itself. It is the cleaner, safer route and is standard market practice.
The essential clauses
- The parties: full legal names and details of assignor and assignee.
- Recitals: the background — what the debt is and how it arose.
- The assignment clause: a clear statement that the assignor assigns the debt and all rights attaching to it.
- What is transferred: the principal, accrued interest, security and enforcement rights.
- Consideration: the price paid for the debt.
- Warranties: confirmations that the debt exists, is owned by the assignor and is free of undisclosed disputes.
- Notice: who will notify the debtor of the assignment.
- Execution: proper signing as a deed, with witnesses as required.
Always annex the underlying debt documentation — invoices, contract, judgment — as a schedule to the deed. It puts beyond doubt exactly what has been sold.
Warranties: what the seller does and does not guarantee
Typically the assignor warrants that the debt exists and is legitimately owned, but does not guarantee the debtor will actually pay. The buyer takes the collection risk — which is precisely why they buy at a discount. Be clear about this split in the deed to avoid disputes later.
Common mistakes to avoid
- Failing to check the underlying contract does not prohibit assignment.
- Not giving written notice to the debtor, leaving only an equitable assignment.
- Vague description of the debt, so it is unclear what was sold.
- Forgetting to transfer accrued interest and security along with the principal.
Do you need a solicitor?
For a straightforward single debt, a well-drafted standard deed may suffice. For portfolios, secured debts or regulated agreements, take legal advice — the cost is small against the value of getting a clean, enforceable transfer.
Conclusion
The deed of assignment is the linchpin of any debt sale. Name the parties, describe the debt precisely, transfer everything that attaches to it, set out the warranties and provide for notice to the debtor. Done properly, it gives the buyer a clean title and the seller a clean exit.
