SDLT on Family Mediation Property Settlements and Equalisation
NO VAT
Can a family property settlement avoid SDLT if ownership shares are changed without consideration?
Introduction
People often ask whether Stamp Duty Land Tax (SDLT) is payable when family members rearrange ownership of jointly held properties as part of a settlement agreement. The answer usually depends on one central question: is there any chargeable consideration for the transfer?
In family disputes, it is common for one person to give up a share in one property while receiving a larger share in another, or for beneficial ownership percentages to be altered to reflect a negotiated outcome. That can create SDLT problems if the arrangement is treated as an exchange, because SDLT can then be charged by reference to market value. On the other hand, if a transfer is genuinely made for no consideration, and no mortgage debt is taken on, SDLT may not arise.
The drafting matters. HMRC will look at the legal effect of the arrangement, not just the labels used in the settlement agreement.
The Question
A reader was involved in a family mediation concerning two jointly connected residential properties. One property was already held in unequal beneficial shares, while the other was also jointly owned. The proposed settlement involved:
- changing the beneficial ownership percentages in one dwelling, and
- the transfer of one co-owner’s share in the other dwelling to the other family member.
The concern was whether SDLT could be avoided if:
- the increase in one person’s share of the first property was documented as a variation of beneficial ownership for no consideration, and
- the transfer of the share in the second property was made for a nominal amount, such as £1, with any mortgage cleared first.
A further question was whether the parties could rely on a “global family settlement” or “equalisation” wording to argue that no part of the arrangement was consideration for a land transfer.
Nick’s Explanation
Nick’s core explanation was that SDLT depends on whether there is a land transaction for chargeable consideration. A transfer of equity can be a land transaction, but if no money is paid and no debt is assumed, the SDLT charge may still be nil.
He explained the position in three stages:
- a gift or variation of beneficial ownership with no mortgage and no payment can be outside the SDLT charge because there is no chargeable consideration;
- a nominal transfer, such as £1, may also escape SDLT if it falls below the statutory threshold and no debt is taken on; but
- if one transfer is made in return for another, HMRC may treat the arrangement as an exchange, in which case market value rules can apply.
In anonymised form, Nick’s key point was:
If the steps are documented as linked exchanges, HMRC could apply the exchange rule, which deems each party to give consideration equal to market value. If, however, one adjustment is documented as a variation for no consideration and the other transfer is for a nominal sum with no debt assumption, there may be no SDLT. The key is to avoid wording that suggests one step is in return for the other.
He also explained that a true partition is a different concept. Partition is most relevant where co-owners divide jointly owned land so that each ends up owning a distinct asset outright. By contrast, simply changing ownership percentages in one property is usually better analysed as a variation of beneficial ownership rather than a partition.
The Law
The main SDLT rules here are found in the Finance Act 2003.
Section 43 charges SDLT on land transactions involving the acquisition of a chargeable interest.
Section 43(3)(c) is relevant because a transfer of an existing equitable interest, or the creation or surrender of rights affecting beneficial ownership, can still be a land transaction.
Section 49 provides that a transaction is not chargeable if there is no chargeable consideration.
Section 55 deals with the amount of tax by reference to chargeable consideration.
Section 108 deals with linked transactions. If separate transfers form part of a single scheme, arrangement or series of transactions, HMRC may aggregate them for rate purposes.
Section 47 and Schedule 4, paragraph 5 are important where there is an exchange. In an exchange, each party is generally treated as giving consideration equal to the market value of what they acquire.
Schedule 4, paragraph 8 provides that assumption of debt, including mortgage debt, can count as chargeable consideration.
Schedule 3, paragraph 1 excludes certain low-value transactions, including where chargeable consideration does not exceed £40,000.
Schedule 4ZA contains the higher rates for additional dwellings.
Where a property is said to be unsuitable for use as a dwelling, the threshold is now relatively high following Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799. A dwelling will not fall outside the residential rules merely because it needs repair, modernisation or substantial works. The condition must be serious enough to meet the now stricter standard established by that case.
Analysis
The SDLT analysis should be carried out step by step.
First, identify each land transaction separately. A change in beneficial shares in one property can itself be a land transaction. A transfer of a share in another property is also a land transaction.
Second, ask what consideration is given for each transaction. Consideration is not limited to cash. It includes:
- money,
- assumption of mortgage debt,
- release from liability, and
- property or rights given in exchange.
Third, ask whether the steps are truly independent, or whether one is given in return for the other. This is where many family settlements become difficult. If one party receives a larger share in Property A because they are surrendering a share in Property B, HMRC may argue that there is an exchange. If that happens, the market value rule in Schedule 4, paragraph 5 may apply.
Fourth, consider whether there is any mortgage or secured debt. Even where no money changes hands, SDLT can arise if the transferee takes over liability for debt. Clearing the mortgage before the transfer can therefore be critical.
Fifth, consider linked transaction risk. Even if the parties try to allocate no consideration to one step and nominal consideration to another, HMRC may still examine the overall arrangement. If the documents, surrounding facts or settlement terms show that the land transfers are reciprocal elements of the same bargain, HMRC may seek to characterise them as linked or as an exchange.
Sixth, consider whether partition is genuinely available. Partition is generally relevant where co-owners divide existing jointly owned property rights so that each emerges with sole ownership of a separate asset or part, without any balancing payment or debt assumption. It is not usually the correct label for a simple reallocation of beneficial percentages in a single property.
Applying those principles to the kind of scenario described:
If one person’s beneficial share in the first property increases from a small minority share to 50%, and that adjustment is genuinely made for no consideration and with no mortgage debt assumed, that step may produce no SDLT charge.
If the same person separately transfers their share in the second property for £1, and the mortgage has been discharged, that step may also produce no SDLT because the consideration is below the £40,000 threshold.
However, if the documents show that the increased share in the first property is being received in return for giving up the share in the second property, HMRC may treat the arrangement as an exchange. In that case, each side can be taxed by reference to market value, and the higher rates for additional dwellings may also need to be considered.
This is why “global settlement” wording is not, on its own, a complete answer. Calling something a compromise of wider family claims does not automatically prevent SDLT if, in substance, there is consideration for a land transfer. HMRC and, if necessary, the tribunal will look at the real legal and factual effect of the arrangement.
Equally, if there are genuinely disputed beneficial interests and the settlement simply recognises or varies those interests without payment, that may support a no-consideration analysis. But the evidence and drafting must fit the underlying reality.
Outcome
The practical conclusion is as follows:
A variation of beneficial ownership can be SDLT-free if no chargeable consideration is given and no mortgage debt is assumed.
A transfer of a share in another property for a nominal amount can also be SDLT-free if it falls below the statutory threshold and no debt is taken on.
But if the two steps are, in substance, part of an exchange, SDLT may arise on market value for both parties.
A partition analysis is only relevant in a narrower class of case and does not usually apply simply because beneficial percentages in one property are being changed.
So the answer is not that a family settlement automatically avoids SDLT. The result depends on whether there is real chargeable consideration and how the arrangement is characterised in law.
Practical Steps
If you are assessing a similar arrangement, the following steps are sensible:
List each proposed land transfer separately, including any change in beneficial ownership.
Check whether any cash, debt assumption, release from liability, balancing payment or transfer of another property interest is involved.
Confirm whether any mortgage will remain in place at completion. If so, calculate whether the transferee is taking on debt for SDLT purposes.
Review the settlement wording carefully. Avoid language stating or implying that one property transfer is “in consideration of”, “in return for” or “in exchange for” another, unless that is truly the intended structure and the SDLT consequences are accepted.
Check whether the arrangement is really a variation of beneficial ownership, a gift, an exchange, or a genuine partition. The label should match the legal substance.
Obtain and retain evidence supporting the factual position, including trust documents, ownership history, mortgage position and any basis for saying that a beneficial entitlement already existed or is being varied without consideration.
Where residential property is involved, consider whether the higher rates for additional dwellings could apply if HMRC characterises the arrangement as chargeable.
If anyone is arguing that a property is not suitable for use as a dwelling, apply the stricter standard from Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799.
Conclusion
A family property settlement can be structured without SDLT, but only where there is genuinely no chargeable consideration and no assumption of debt. If the arrangement is really an exchange of property rights, market value SDLT rules may apply. In these cases, the legal character of the transaction and the exact drafting of the settlement documents are crucial.
