Property Assignment Agreement UK
What a property assignment agreement covers, how an off-plan contract is assigned, developer consent, legal requirements and SDLT considerations
A property assignment agreement is used when a purchaser wants to transfer their contractual rights under a property purchase agreement to another buyer before the original transaction is completed.
This is particularly common with off-plan flats and new-build developments. Instead of completing the original purchase and then selling the completed property, the original purchaser may be able to transfer their contractual position to another party.
The arrangement needs to be structured carefully because the original purchase contract, developer's requirements and tax rules can all affect the transaction.
What is a property assignment agreement?
A property assignment agreement records the transfer of contractual rights from the original purchaser to another party.
For example, an investor may agree to purchase an off-plan apartment from a developer for £400,000. Before completion, the investor finds another buyer willing to take over the contractual position.
If the original contract permits assignment, the investor may assign their rights to the new purchaser under an appropriate legal agreement.
The new purchaser then proceeds towards completion under the original purchase arrangement, subject to the terms of the assignment and any required developer consent.
HMRC specifically recognises assignments of rights as a type of pre-completion transaction for SDLT purposes.
What should a property assignment agreement contain?
The exact wording should be prepared by a suitably qualified solicitor because every transaction can have different contractual requirements.
An agreement may typically identify:
-
The original purchaser or assignor
-
The incoming purchaser or assignee
-
The original seller or developer
-
The property or development
-
The original purchase agreement
-
The rights being assigned
-
The agreed assignment consideration
-
Any deposit already paid
-
The remaining purchase price
-
Developer consent requirements
-
Completion arrangements
-
Each party's obligations
-
Responsibility for fees and costs
-
Conditions that must be satisfied before completion
-
Warranties or representations
-
What happens if the assignment does not complete
The agreement should also make clear whether contractual obligations are being transferred or whether only particular rights are being assigned.
Assignment of rights versus novation
These terms should not be treated as interchangeable.
An assignment generally concerns the transfer of contractual rights. A novation can replace one contracting party with another and may transfer both rights and obligations.
For example, if the original purchaser has continuing obligations under the developer's contract, simply assigning certain rights may not release them from those obligations.
Whether an assignment, novation, subsale or another structure is appropriate depends on the original contract and circumstances.
A property solicitor should determine the correct structure before the parties sign anything.
Check the original purchase contract first
Before preparing an assignment agreement, the original purchase contract should be reviewed.
Look specifically for clauses covering:
-
Assignment
-
Transfer
-
Resale before completion
-
Developer consent
-
Administration fees
-
Restrictions on assigning to third parties
-
Deadlines for assignment
-
Minimum or maximum assignment periods
-
Purchaser obligations
-
Default provisions
Some developers permit assignments subject to conditions, while others may restrict them significantly.
If the contract requires written consent, the purchaser should obtain that consent before proceeding with the assignment.
Developer consent for an assignment
Off-plan developments commonly have specific procedures for transferring a purchase contract.
The developer may require details of the incoming buyer and may need to approve the proposed assignment.
Depending on the contract, the developer could request:
-
Identification documents
-
Proof of funds
-
Details of the assignee
-
Solicitor details
-
A copy of the proposed assignment documentation
-
Payment of an administration or assignment fee
The developer's approval should be documented properly rather than relying on a verbal indication that the assignment is acceptable.
How much does an assignment agreement cost?
There is no single standard fee for preparing or handling a property assignment agreement.
Legal costs can depend on:
-
The complexity of the original contract
-
Whether developer consent is required
-
Whether the property is off-plan
-
Whether a company is involved
-
Whether the transaction involves an assignment premium
-
Whether a novation or subsale is required
-
The number of parties involved
-
Additional due diligence
-
Tax advice
-
Negotiations with the developer's solicitor
There may also be separate developer administration fees.
Before instructing a solicitor, ask for a detailed quotation explaining what is included and which costs could be charged separately.
Assignment consideration and the purchase price
An assignment can involve an additional payment to the original purchaser.
For example:
Original purchase price: £350,000
Deposit already paid: £35,000
Assignment payment: £25,000
Balance under original contract: £315,000
The precise payment structure will depend on the legal arrangement.
The £25,000 assignment payment should be clearly documented. The parties should also understand how the original deposit and remaining purchase price will be dealt with.
Importantly, the assignment payment should not automatically be treated as the seller's net profit because legal costs, developer fees, financing costs and tax may affect the final position.
SDLT on a property assignment agreement
Tax is an important part of an assignment transaction in England.
HMRC's current guidance states that, broadly, where rights under a property purchase contract are assigned before completion, the consideration for the incoming purchaser can include what they give under the original contract together with what they give for the assignment.
HMRC provides an example involving an original £1 million purchase contract followed by a £100,000 assignment payment. In that example, the eventual purchaser's SDLT consideration is £1.1 million.
This demonstrates why the parties should obtain professional tax advice before agreeing an assignment price.
There are also specific circumstances in which the original purchaser may be able to claim relief for their transaction. HMRC states that relief can apply to qualifying assignments or subsales, subject to the relevant conditions.
The rules are technical, and an assignment should not be structured solely on the assumption that it will produce a particular SDLT result.
Is a property assignment agreement the same as selling a property?
No.
A conventional property sale normally involves an owner transferring an existing property to a buyer.
An assignment before completion can instead involve the original purchaser transferring contractual rights before acquiring the completed property.
This distinction is particularly important with off-plan apartments.
For example, if a developer is still constructing a flat and the original purchaser has not completed, the purchaser may have contractual rights rather than ownership of the completed property.
The legal documentation therefore needs to reflect the actual position.
Can you create your own property assignment agreement?
It is possible to find generic assignment agreement templates, but using an unadapted template for an actual property transaction can create significant problems.
The agreement needs to work alongside the original purchase contract and any developer requirements.
A solicitor should check:
-
Whether the rights are legally assignable
-
Whether consent is required
-
Whether obligations also need to be transferred
-
Whether the assignment is conditional
-
How consideration is treated
-
Whether the developer must execute or acknowledge the document
-
Whether the transaction creates SDLT consequences
-
Whether additional documentation is required
This is particularly important where substantial sums have already been paid.
Assignment agreement for an off-plan flat
Off-plan flats are one of the situations where property assignment agreements are particularly relevant.
Suppose an investor reserved an apartment for £450,000 during the early construction stage. The investor later decides not to complete the purchase.
If the developer's contract permits assignment, the investor could potentially find an incoming purchaser and transfer the contractual position.
Before doing so, the investor should establish:
-
Whether assignment is permitted.
-
Whether developer consent is required.
-
What assignment fee applies.
-
How much has already been paid.
-
What remains payable.
-
Whether the incoming purchaser meets the developer's requirements.
-
What legal structure should be used.
-
What tax consequences arise.
This can help prevent a commercially attractive transaction from becoming delayed by a contractual or legal issue discovered too late.
What if the developer refuses the assignment?
If developer consent is required and the developer refuses, the original purchaser should obtain legal advice before proceeding.
Depending on the original contract, the parties may explore whether the developer will agree to a variation, whether another permitted structure is available or whether the original purchase must proceed.
The answer will depend on the precise wording of the contract.
An assignment agreement cannot simply override a contractual restriction imposed by the original seller or developer.
Property assignment agreements and Fraser Bond
Fraser Bond can support investors and property owners considering the commercial side of an off-plan assignment.
Our property consultancy services can assist with assessing the property's market position, understanding the commercial implications of an assignment, identifying potential buyers and coordinating with relevant property professionals.
The assignment agreement itself should be prepared and reviewed by a suitably qualified solicitor or conveyancer. Legal and tax advice is particularly important where the transaction involves an assignment premium, developer restrictions or significant sums.
Getting the original purchase contract reviewed before marketing the property can help establish whether an assignment is possible and what conditions need to be satisfied.
