Guide to SDLT Requirements for Land Registration and Subsale Transactions

Registering Land After a Subsale or Assignment of Rights for SDLT

When land is sold on before registration, the Land Registry will usually need proof that the correct SDLT requirements have been met before it will register title. What is needed depends mainly on whether there are two actual transfers of the land or only one, and whether the arrangement is a true subsale or an assignment of contractual rights.

• Under Finance Act 2003 section 79, registration of most notifiable land transactions normally requires an SDLT5 certificate for the relevant registrable transaction.
• If there are two actual transfers, from A to B and then B to C, the registration evidence must show the full chain of title through both transfers.
• If C applies to register without B having registered first in a two-transfer subsale, C will usually need C’s SDLT5, the registration application, both transfer documents, and possibly written confirmation that the arrangement is a free-standing transfer under Schedule 2A.
• If there is only one actual transfer, from A directly to C, C normally only needs C’s SDLT5, the application, and the A-to-C transfer.
• In an assignment of rights, the notional SDLT transaction between A and B does not create a separate registration requirement, so no separate SDLT certificate or letter for that notional step is usually needed.
• The legal structure and documents matter more than the label used by the parties, because subsales and assignments can look similar commercially but have different registration consequences.

Registering land after a subsale or assignment of rights for SDLT purposes

This page explains how SDLT interacts with Land Registry registration where land is sold on before registration. The key point is that the Land Registry will usually require evidence that the relevant SDLT obligations have been met before it will register the buyer’s interest. In subsale and assignment arrangements, working out whose SDLT certificate is needed, and what supporting documents must be filed, depends on how the transaction is structured.

What this rule is about

Finance Act 2003 section 79 restricts registration of land acquired in most notifiable land transactions unless the applicant produces a certificate showing compliance with SDLT requirements. In practice, this certificate is the SDLT5.

This matters where there is more than one step between the original seller and the person who ends up seeking registration. That often happens in:

• a subsale, where B agrees to buy from A and then sells on to C
• an assignment of rights, where B passes contractual rights to C and the land is then transferred directly from A to C

Although these arrangements can look similar commercially, the registration consequences are not the same.

What the official source says

The HMRC manual says that section 79 prevents registration unless the person applying to register can produce the required SDLT certificate.

It then distinguishes between three situations.

First, in a subsale where there are two actual transfers of the land, from A to B and then from B to C:

• if B wants to register B’s own interest, B must produce B’s SDLT5 with the application and the transfer from A to B
• if B does not register, and C applies to register, C must produce C’s SDLT5, the application for registration, and both transfers: A to B and B to C

In that second case, HMRC says C should also provide written confirmation that B acquired from A and transferred to C under a “free-standing transfer” for the purposes of Schedule 2A Finance Act 2003. That confirmation can come either from C or from B or B’s agent.

Second, if there is only one transfer of the land, from A to C, then C only needs to produce C’s SDLT5, the registration application, and the transfer from A to C.

Third, in an assignment of rights, there is only one transfer of the land, from A to C. HMRC says C can register in the normal way. Although there is a notional land transaction between A and B for SDLT purposes, section 79 does not apply to that notional transaction. No separate letter confirming assignment of rights is needed. Only C’s SDLT5 is required.

What this means in practice

The practical question is not just whether SDLT is due. It is whether the Land Registry needs proof of SDLT compliance for the transaction that is relevant to registration.

If there are two actual conveyances, the paperwork must show the chain of title through both transfers. If the intermediate buyer B never registers, C still has to explain how title moved from A to B and then from B to C. That is why both transfers are needed.

Where the arrangement falls within HMRC’s “free-standing transfer” treatment under Schedule 2A, HMRC also expects written confirmation of that point when C applies to register without B having registered first.

By contrast, where the arrangement is an assignment of rights and the only actual transfer is from A to C, the Land Registry process is simpler. The notional transaction between A and B may matter for SDLT analysis, but it is not itself something that can be registered, so section 79 does not require an SDLT certificate for that notional step.

The result is that C usually registers in the ordinary way using the SDLT5 for the actual transfer to C.

How to analyse it

A sensible way to approach the issue is to ask these questions in order.

• How many actual land transfers are there? One or two?
• Who is applying to be registered: B or C?
• Is B’s step an actual transfer of the land, or only a transfer of contractual rights?
• If there are two transfers and C is registering without B having registered, is the transaction being treated as a free-standing transfer under Schedule 2A?
• What documents show the full chain from the original seller to the applicant?
• Which SDLT5 corresponds to the registrable transfer being relied on?

In practical terms:

• two actual transfers usually mean more registration evidence is needed
• one actual transfer usually means the registration process is more straightforward
• a notional SDLT transaction does not automatically create a separate registration requirement

Example

Illustration: A contracts to sell land to B. Before registration, B sells the land on to C.

If A transfers to B, and B then transfers to C, there are two actual transfers. If C applies to register without B having registered first, C should provide C’s SDLT5, the application, both transfer documents, and written confirmation that B’s acquisition and onward transfer were in pursuance of a free-standing transfer if that Schedule 2A treatment applies.

If instead B simply assigns the benefit of the contract to C and A transfers directly to C, there is only one actual transfer. C registers in the normal way using C’s SDLT5 and the A-to-C transfer. On HMRC’s view, no separate letter about the assignment of rights is required for section 79 purposes.

Why this can be difficult in practice

The main difficulty is that subsales and assignments of rights can look similar commercially, but they are not the same legally.

The registration position depends on the actual documents and steps taken, not just on how the parties describe the arrangement. A file may refer loosely to a “subsale” even where there has only been an assignment of contractual rights and one actual conveyance. Equally, what appears to be a simple onward sale may in fact involve two transfers and therefore extra registration evidence.

Another point of care is that HMRC’s manual refers specifically to a “free-standing transfer” for the purposes of Schedule 2A. Whether that description applies depends on the underlying SDLT analysis. The manual explains what confirmation should accompany the registration application if that treatment is being relied on, but it does not replace the legislation.

It is also important not to confuse:

• the SDLT treatment of a transaction
• the Land Registry evidence needed to register title

They are linked, but they are not identical questions.

Key takeaways

• Registration usually requires an SDLT5 for the relevant registrable transaction under Finance Act 2003 section 79.
• In a subsale with two actual transfers, C may need both transfer documents and confirmation of a free-standing transfer if B has not registered.
• In an assignment of rights with only one actual transfer from A to C, HMRC says only C’s SDLT5 is needed for registration purposes.
