Transfer of Property to a Spouse & Stamp Duty

The Transfer of Property to a Spouse

This blog looks at the rules regarding stamp duty (SDLT) which apply to a transfer of property to a spouse.

Important scope note: SDLT applies to property in England and Northern Ireland. Property in Wales is subject to Land Transaction Tax (LTT), and property in Scotland is subject to LBTT.

Transfer of equity

A transfer of property to a spouse is known as a transfer of equity.  A transfer of equity just means a change in the legal ownership of a property, usually where at least one owner remains on the property. It will often take place where a borrower is added to or released from a mortgage. Equity is the value of the property after repayment of any outstanding loan.

A transfer of equity can most often occur as a result of a breakdown between spouses or partners where the joint names need to be transferred to the sole name of the person who will remain at the property. It can also be especially useful for family or estate planning reasons, subject to lender requirements where the property is mortgaged.

Is Stamp Duty payable when completing a transfer of equity?

SDLT is payable only where there is “chargeable consideration” for the transfer and the chargeable consideration exceeds the relevant SDLT threshold(s). Chargeable consideration can include money or other value paid for the share being transferred and, crucially, the assumption of debt (for example, where the incoming spouse takes on responsibility for all or part of the outstanding mortgage). This is why SDLT can be payable even where no cash changes hands.

Lender’s Consent When Transferring Equity to a Spouse

If the property is mortgaged, your lender’s consent will typically be required before completing a transfer of equity. This is because the transfer alters the legal ownership of the property and can affect the lender’s security interest. The lender will usually need to review the proposed changes and may require a new or amended mortgage deed to reflect the updated ownership. They may also require affordability checks and specific documentation depending on their instructions. Failing to obtain consent can delay the process or even breach the terms of your mortgage.

Our solicitors can liaise directly with your lender to secure consent and ensure that the transfer proceeds smoothly and in compliance with all lending requirements.

Higher Rates – 3% Surcharge 

Whether the 3% higher rates for additional dwellings (HRAD) apply is determined at completion (the “effective date”) and depends on whether the transaction counts as the acquisition of an additional dwelling and whether the “replacement of only or main residence” rules apply.

For couples who are married or in a civil partnership and “living together” for tax purposes, the rules treat them as a single unit, so each spouse’s/civil partner’s property interests (including those held overseas) are taken into account when testing the surcharge. Where spouses/civil partners are separated in a manner recognised by the SDLT rules, they are tested individually.

HMRC guidance confirms that a transfer between spouses/civil partners where no one else is involved is not charged at the higher 3% rates (standard SDLT rules still apply). Assumption of mortgage debt by the transferee spouse/civil partner counts as chargeable consideration, so SDLT at the standard residential rates may still be payable even if no cash changes hands.

Broadly, HRAD does not apply if the purchaser is replacing their only or main residence and has disposed of the previous one by completion; if the sale of the former main residence takes place within three years after purchase, a refund of the 3% element can usually be claimed (subject to conditions, including post‑2018 anti‑avoidance where either spouse retains an interest in the former home).

• Inter-spousal transfer of the main home (no HRAD; standard rules would still apply): A Husband (H) owns the couple’s main home (value £600,000; mortgage £300,000) and transfers 50% to his Wife (W), who assumes £150,000 of the mortgage. Because the transfer is solely between spouses living together, the 3% higher rates (HRAD) do not apply. SDLT is assessed at the standard residential rates on £150,000 (the assumed debt). An SDLT return is generally required if consideration is £40,000 or more.
• Buy-to-let purchase while living together (HRAD applies): A Husband (H) and Wife (W) are married and living together. W already owns a flat. H buys a £300,000 buy-to-let. As spouses living together are treated as one unit, W’s existing flat is attributed to H for testing; H’s purchase is an additional dwelling and HRAD applies (unless the replacement-of-main-residence exception is met).
• Replacing the main residence on the same day (no HRAD): A Husband (H) and Wife (W), living together, sell their current main residence and simultaneously buy a new main residence. Provided neither retains any interest in the property sold, the replacement rules apply and HRAD does not.
• Replacing the main residence with sale within three years (refund): A Husband (H) buys a new main residence before selling the old one; the 3% surcharge (HRAD) is paid on completion. If H (and W, if relevant) sell the former main residence within three years, H can generally claim a refund of the 3% element (subject to the spousal attribution rules and all statutory conditions).
• Permanently separated spouses (no spousal attribution): A Husband (H) and Wife (W) are separated “in circumstances likely to be permanent.” W owns a let flat. H buys a first home to live in. W’s property is not attributed to H for HRAD; if H owns no other dwellings and is not buying an additional property, HRAD is not in point and standard rates apply (first-time buyer relief may be available if all conditions are met).

Note: Civil partners are treated the same as spouses for HRAD purposes (Finance Act 2003, Sch 4ZA).

Key legal framework: Finance Act 2003, Schedule 4ZA (including spousal attribution and replacement of main residence rules); “living together” takes its meaning from the Income Tax Act (ITA) 2007, s.1011. HMRC’s higher rates guidance confirms that inter‑spousal/civil partner transfers with no third party involved are not charged at HRAD, though standard SDLT rules (including debt assumption as consideration and return requirements) still apply.

You might also have to pay SDLT even when no money changes hands

SDLT is charged on “chargeable consideration”, which includes not only cash paid but also any mortgage debt that the transferee agrees to take over. In pure inter‑spousal/civil‑partner transfers (with no third party involved), the 3% higher rates (HRAD) do not apply; however, the standard SDLT rules still apply to any consideration given (including assumed debt), and an SDLT return is generally required where consideration is £40,000 or more.

Take the following example: the owner of a property valued at £500,000 with an outstanding mortgage of £400,000 transfers half the property to their spouse or civil partner when they marry, or enter into a civil partnership. The transferee spouse/civil partner takes on 50% of the mortgage (£200,000).

As at 1 April 2025, the general residential nil‑rate threshold is £125,000. In this example, the chargeable consideration is £200,000 (the assumed mortgage debt). SDLT is calculated at the standard residential rates: 0% on the first £125,000 and 2% on the next £75,000, giving £1,500. Because the consideration is £40,000 or more, an SDLT return is generally required.

Trusts and SDLT

SDLT applies to “land transactions” where someone acquires a chargeable interest in land (Finance Act 2003). A transfer or creation of a beneficial interest can be a land transaction if a beneficial share in the property is actually acquired. Where legal ownership and beneficial interests align things are straightforward: the owner pays SDLT based on the full value. However, if legal title changes hands but the beneficial ownership does not (for example, a nominee/bare trustee is appointed), there is usually no SDLT because no beneficial interest has been acquired. Conversely, if a beneficial interest is transferred (for example, 50% of the equity is given to a spouse), SDLT may arise if there is “chargeable consideration” (cash paid or debt assumed). Special regimes apply in certain structures (e.g., partnerships under Finance Act 2003 Sch 15), but there is no general “double taxation” simply because a trust is involved.

A declaration of trust can be used either to confirm that the legal owner holds as a bare trustee (no change in underlying beneficial ownership), or to transfer/define beneficial shares. If the declaration merely confirms an existing bare trust (no change in beneficial ownership), there is generally no SDLT. If it transfers a new beneficial share, SDLT may be due if there is chargeable consideration (including assumption of mortgage debt). However, the SDLT position turns on whether a chargeable interest is acquired and whether chargeable consideration is given; contemporaneous documentation is still important to evidence the intended beneficial shares.

Easy-to-understand examples

• Example 1 – Adding a spouse to the deeds but keeping 100% of the beneficial interest (no SDLT): A Husband (H) owns a flat outright (no mortgage). H adds his Wife (W) to the legal title but signs a declaration of trust confirming H retains 100% of the beneficial interest and W has 0%. Because W acquires no beneficial interest, there is no acquisition of a chargeable interest and generally no SDLT is due. If a mortgage exists and W assumes no liability and has no beneficial interest, the analysis is the same (but lender consent and formalities are still required).
• Example 2 – Gifting a 50% beneficial share where there is no mortgage (usually no SDLT): A Husband (H) owns a house mortgage‑free. H executes a declaration of trust gifting his Wife (W) a 50% beneficial interest for no payment. As there is no chargeable consideration (no cash and no debt to assume), SDLT is generally not payable. Note: the 3% “additional property” surcharge (HRAD) does not apply to a pure inter‑spousal transfer where no one else is involved; standard SDLT rules still govern whether any tax is due.
• Example 3 – Transferring a 50% beneficial share subject to a mortgage (SDLT on assumed debt): A Husband (H) owns a house worth £500,000 with a £300,000 mortgage. H gives his Wife (W) a 50% beneficial interest. W becomes liable for 50% of the mortgage (£150,000). The assumed debt (£150,000) is “chargeable consideration”. SDLT is calculated at the standard residential rates on £150,000 (an SDLT return is generally required because consideration is ≥ £40,000). The 3% HRAD surcharge does not apply to a pure inter‑spousal transfer with no third party involved, but would need separate analysis in non‑spousal cases.

Key points to remember

• SDLT looks at whether a chargeable interest has been acquired and whether there is chargeable consideration (cash or debt assumption).
• Assumption of mortgage debt by the transferee is treated as consideration.
• A change in legal title only (with no change in beneficial ownership) typically does not give rise to SDLT.
• Inter‑spousal/civil partner transfers with no third party involved are not charged at the 3% HRAD rates, but normal SDLT rules (including debt‑assumption as consideration and return requirements) still apply.
• Documentation (e.g., declarations of trust, lender consents) is essential to evidence beneficial shares and ensure compliance.

Is stamp duty payable in a transfer of equity following a divorce?

There are certain circumstances in which you do not need to pay stamp duty in a transfer of equity between spouses. These circumstances are usually in cases where a couple are:

• Divorcing
• Dissolving a civil partnership
• Annulling their marriage
• If they are legally separate

Can a solicitor act for both parties in a transfer of equity between spouses?

If the transfer of equity is occurring between family and they confirm that there is no conflict of interest, the solicitor is able to act for both parties; particularly in situations where parties are being added to the title, the solicitors are able to act on behalf of both parties. Lenders are generally happy to accept this position as long as the security of the loan is protected.
