Divorce Stamp Duty: Exemptions, Buyouts & Worked Examples
The SDLT rules for property transfers during divorce or civil partnership dissolution: when the Schedule 3 exemption removes the bill, when SDLT still applies on buyouts and mortgage assumptions, regional LBTT/LTT differences, and worked numbers. For the legal/conveyancing process (court order types, deed mechanics, paperwork), see divorce property transfer.
Key Takeaways
- Property transfers under a court order during divorce or dissolution of a civil partnership are exempt from SDLT under Schedule 3 paragraph 3 Finance Act 2003
- Chargeable consideration still matters: cash paid PLUS any mortgage share assumed both count as consideration when one spouse buys out the other outside an exempt court order
- An informal separation agreement, even one drafted by solicitors, does NOT qualify for the exemption without court approval and sealing
- Cohabiting (unmarried) partners have no access to the court order exemption on separation; standard SDLT rules apply to any buyout
- A court-ordered exempt transfer does NOT make the recipient an "additional property" owner for future SDLT surcharge purposes
- Scotland uses LBTT with an equivalent exemption administered by Revenue Scotland; Wales uses LTT with an equivalent exemption under the Land Transaction Tax and Anti-avoidance of Devolved Taxes (Wales) Act 2017
- For a wholly exempt divorce transfer, GOV.UK confirms there is no need to file an SDLT return at all, provided no chargeable consideration arises

Quick Answer
The Core Rule
Property transfers made under a court order or consent order during divorce or civil partnership dissolution are exempt from SDLT (Schedule 3 paragraph 3 Finance Act 2003). This applies regardless of the property value.
Important exception: SDLT still applies when chargeable consideration is paid outside that court-order protection. This includes cash paid to buy out an ex-spouse and any share of an existing mortgage assumed by the incoming sole owner.
This page covers the legal SDLT position on transfers happening as part of divorce proceedings. If you are divorced and planning your next property purchase, the questions around first-time buyer status, the 5% additional property surcharge, and sequencing strategies are covered in our divorce and future stamp duty guide.

The Schedule 3 Exemption Explained
The statutory authority for the divorce SDLT exemption is Schedule 3 paragraph 3 of the Finance Act 2003. In plain English, it says:
Source: Finance Act 2003, Schedule 3 paragraph 3 (as amended by the Divorce, Dissolution and Separation Act 2020 with effect from 6 April 2022)
Who qualifies?
- Married couples going through divorce, annulment, or judicial separation in England and Northern Ireland
- Civil partners whose partnership is being dissolved (extended by the Civil Partnership Act 2004)
- Parties to a Scottish marriage or civil partnership (LBTT equivalent rules, see below)
What counts as a "court order" for Schedule 3?
The exemption covers transfers made under:
- a)An order made by the court on granting the divorce/annulment/judicial separation
- b)An order made after that decree in connection with the dissolution
- c)An order under sections 22A, 23A or 24A of the Matrimonial Causes Act 1973 (periodical payments, property adjustment orders)
- d)An agreement of the parties made in contemplation of or in connection with the dissolution (this covers consent orders and certain pre-court agreements drafted for submission to court)
Timing is critical
The property transfer must be executed after the court order is sealed, not before. A transfer that precedes the order does not fall within Schedule 3 and SDLT will apply at standard rates.
When SDLT Still Applies During a Divorce Transfer
The court order exemption is broad, but there are four clear scenarios where SDLT will still be charged.
1. Buying out an ex-spouse's share (chargeable consideration applies)
Where one spouse pays cash to the other for their equity share, or assumes responsibility for a larger portion of the mortgage, chargeable consideration arises. The exemption in Schedule 3 only removes SDLT liability where there is no chargeable consideration, or where the transaction is otherwise within the court order. If you pay £50,000 cash plus assume a £300,000 mortgage to gain full ownership, SDLT is assessed on £350,000 total consideration (see Worked Examples below).
Note: GOV.UK confirms that "you do not pay Stamp Duty Land Tax if you transfer an interest in land or property to your partner as part of an agreement or court order" on divorce. However, this refers to the transfer itself being court-ordered without additional out-of-settlement payments. Where a buyout occurs with real monetary consideration, SDLT is calculated on that consideration.
2. Transfers outside a court order (pre-financial-order agreements)
A solicitor-drafted separation agreement, a heads of terms document, or a private Deed of Separation does not attract the Schedule 3 exemption unless it is subsequently approved and sealed by a court. Couples who transfer property informally before obtaining a court order must pay SDLT on any chargeable consideration.
3. Transfers between unmarried or cohabiting partners
Schedule 3 paragraph 3 only applies to marriages and civil partnerships. Cohabiting partners who split up have no access to the court order exemption. Any transfer of one partner's interest to the other is a standard land transaction: SDLT is assessed on the chargeable consideration (cash paid plus mortgage share assumed). See the Cohabiting Partners section below.
4. Separation agreements without court approval
Even if both parties agree on paper, a separation agreement that is never submitted to court and never sealed as a consent order is not a "court order" for Schedule 3 purposes. SDLT applies at standard rates on any chargeable consideration.
Common mistake: Transferring property before obtaining the court order, intending to apply for the order retroactively. This does not work. The transfer must be executed after the order is sealed. A retroactive order does not exempt a transfer that has already completed.
Mortgage Assumption as Chargeable Consideration
When one spouse assumes the other's share of an outstanding mortgage as part of a buyout, HMRC treats the mortgage share assumed as chargeable consideration. This is one of the most frequently misunderstood points in divorce SDLT planning.
The HMRC rule
Chargeable consideration for SDLT includes "any debt" that the buyer takes on as part of the transaction. When a property is jointly owned 50:50 and one spouse takes over the whole mortgage by refinancing into their sole name, they have "assumed" the other's 50% mortgage liability. That assumed debt is treated as consideration paid for the transfer of the other 50% share.
Worked Example: Buyout with £300k mortgage
Note: From 1 April 2025, the nil-rate threshold for residential property is £125,000. The 0% band applies up to £125,000; 2% from £125,001 to £250,000. Before 1 April 2025, the nil-rate band was £250,000, so the same £150,000 transfer would have attracted £0 SDLT.
The formula
Chargeable consideration = cash paid + (mortgage balance x share being transferred)
If the transfer is made under a Schedule 3 court order and the only "payment" is the mortgage assumption inherent in the transfer, GOV.UK confirms that no SDLT is due and no return is needed. However, if the buying spouse separately pays cash above and beyond what is directed by the court order, that additional cash is chargeable consideration.
Practical tip: Structure the court order to include all financial elements of the property transfer, including the mortgage assumption. A well-drafted consent order that explicitly covers the mortgage responsibility transfer gives the strongest Schedule 3 protection.
Civil Partnership Dissolution
The Schedule 3 exemption was extended to civil partnerships by the Civil Partnership Act 2004. The rules are identical:
- Property transfers made pursuant to a court order in civil partnership dissolution proceedings are exempt from SDLT
- The order can be a dissolution order, a financial remedy order, or a property adjustment order made under the Civil Partnership Act 2004
- The timing rule is the same: transfer must occur after the order is sealed, not before
- Unmarried same-sex couples (not in a civil partnership) are in the same position as unmarried opposite-sex couples: no court order exemption applies
GOV.UK guidance explicitly confirms: "This also applies if the partners either annul their marriage or legally separate," and the same rule covers dissolution of civil partnerships.
Scotland: LBTT Equivalent Rules
Scotland replaced SDLT with Land and Buildings Transaction Tax (LBTT) from 1 April 2015. The divorce exemption equivalent is found in Schedule 1 to the Land and Buildings Transaction Tax (Scotland) Act 2013.
Key points for Scotland
- The exemption principle is the same: transfers under a court order in connection with divorce or dissolution are exempt from LBTT
- The Finance Act 2003 Schedule 3 paragraph 3(c)(ii) expressly includes incidental orders under section 8(2) of the Family Law (Scotland) Act 1985, reflecting Scotland's distinct family law framework
- Revenue Scotland administers LBTT; their LBTT guidance confirms the divorce exemption
Scottish LBTT rate difference
Where SDLT does arise on a buyout (e.g., the buying spouse pays cash or assumes a large mortgage), Scottish LBTT rates apply instead of English SDLT rates. The nil-rate threshold for residential LBTT is £145,000, compared to £125,000 for SDLT in England and Northern Ireland. The Additional Dwelling Supplement (ADS) in Scotland is 8% (as of December 2024).
For detailed Scottish rates, see our Scotland LBTT complete guide.
Wales: LTT Equivalent Rules
Wales replaced SDLT with Land Transaction Tax (LTT) from 1 April 2018. The divorce exemption is found in Schedule 3 to the Land Transaction Tax and Anti-avoidance of Devolved Taxes (Wales) Act 2017, mirroring the SDLT position.
- Transfers under a court order during divorce or dissolution are exempt from Welsh LTT
- The Welsh Revenue Authority (WRA) administers LTT and applies the same principles
- Where chargeable consideration does arise, Welsh LTT rates apply (nil-rate threshold: £225,000 for residential property in Wales)
For detailed Welsh rates and the higher rate (additional dwelling) structure, see our Wales LTT complete guide.
Cohabiting Partners Splitting Up
Unmarried cohabiting partners have no access to the Schedule 3 court order exemption. This is one of the starkest differences between married and unmarried couples in property law.
When cohabiting partners split up and one buys out the other, the standard SDLT rules apply in full:
Typical cohabiting separation scenarios
Scenario A: Ex-partner buyout (equal share, mortgage)
Two unmarried partners own a property 50:50. One leaves and the remaining partner buys out their 50% share. Chargeable consideration = cash paid for their equity share + 50% of the outstanding mortgage assumed. SDLT is due on that total if it exceeds the threshold.
Scenario B: Unequal split (one partner paid more)
If one partner owns 70% and the other 30%, and the 70% owner buys out the 30%, SDLT is assessed on 30% of the outstanding mortgage plus any cash paid for that 30% share.
Scenario C: Joint property, one partner has other properties
If the buying partner already owns another residential property, the 5% additional dwelling surcharge applies on top of standard SDLT rates, provided the chargeable consideration exceeds £40,000.
Note: GOV.UK explicitly states: "If joint owners are unmarried and not in a civil partnership when they transfer an interest in land or property from one joint owner to another then you may have to pay Stamp Duty Land Tax." The no-consideration exemption (zero consideration = no SDLT) still applies, but the court order protection does not.
Critical: 5% Surcharge Interaction
One of the most important and least understood aspects of the divorce SDLT exemption is its interaction with the 5% additional dwelling surcharge.
The rule that catches many people out
A property received by one spouse under a court-ordered exempt divorce transfer does NOT make that spouse an "additional property" owner for the purposes of the 5% surcharge on any future residential property purchase.
Why this matters
Suppose Wife receives the family home under a consent order and Husband moves out. Later, Husband buys a new property. Some people assume Husband must pay the 5% surcharge because Wife still owns a property and they were both on the title. This is wrong:
- The transfer under the court order is exempt from SDLT
- Husband no longer has an interest in the family home after the court-ordered transfer
- Husband's future purchase is not "an additional dwelling" because he no longer owns the former family home
Conversely, if Husband retains the family home under the order but Wife also later buys a new property, Wife would need to check whether the surcharge applies based on her own ownership position, not Husband's retained home.

SDLT Return Requirements for Exempt Transfers
For a wholly exempt divorce transfer (court-ordered, no chargeable consideration), GOV.UK states:
"In these cases there's no need to tell HMRC about the transfer, even if the value is more than the Stamp Duty Land Tax threshold."
Source: GOV.UK, Stamp Duty Land Tax: transfer ownership of land or property
This means that for a standard court-ordered divorce transfer where one spouse simply transfers their share to the other (with no cash payment and no separate mortgage assumption outside the court order), no SDLT1 return is required.
When a return IS still required
- Where there is chargeable consideration (cash or mortgage assumption) that exceeds the nil-rate threshold, an SDLT1 return must be filed within 14 days of completion
- Where the transaction involves a lease or commercial element (uncommon in divorce), filing obligations differ
- Your conveyancer may still file a return for their own records even when not strictly required; this is at their discretion
Practical note: Some conveyancers file a voluntary SDLT1 return even for exempt divorce transfers, noting the relief code. This creates a paper trail for Land Registry and HMRC. While not legally required for a wholly exempt transfer, it is a matter of professional practice. Ask your solicitor what approach they will take.
Worked Examples
Example A: Clean court-ordered transfer (no SDLT)
Result: No SDLT. No SDLT1 return required.
The transfer is made pursuant to a sealed consent order. There is no chargeable consideration. Schedule 3 paragraph 3 FA 2003 applies fully.
Example B: Buyout with £300k mortgage + £50k cash
SDLT calculation on £200,000 (post-April 2025 rates):
| Band | Amount | Rate | Tax |
|---|---|---|---|
| £0 to £125,000 | £125,000 | 0% | £0 |
| £125,001 to £200,000 | £75,000 | 2% | £1,500 |
| Total SDLT | £1,500 | ||
An SDLT1 return must be filed within 14 days of completion. No Schedule 3 exemption applies because chargeable consideration arises outside the exempt transfer.
Example C: Unmarried couple splitting joint property
SDLT: £500 (2% on £25,000 above the £125,000 nil-rate threshold)
No Schedule 3 exemption: the parties are not married or in a civil partnership. Standard SDLT rules apply in full. An SDLT1 return is required.

Frequently Asked Questions
Do you pay stamp duty on a property transfer in divorce?
Not if the transfer is made under a court order in connection with the divorce (Schedule 3 paragraph 3 Finance Act 2003). The exemption applies regardless of property value and regardless of whether consideration changes hands as part of the settlement. GOV.UK confirms that no SDLT return is even required for a wholly exempt divorce transfer. However, if a buyout involves cash or mortgage assumption outside the terms of the court order, SDLT is assessed on that chargeable consideration.
When does the court order exemption from SDLT apply?
The exemption applies when four conditions are met: (1) the parties are married or in a civil partnership, (2) divorce, dissolution, annulment, or judicial separation proceedings are underway or have concluded, (3) the property transfer is made pursuant to a court order sealed in those proceedings (consent order, financial remedy order, property adjustment order, or similar), and (4) the transfer is executed after the order is sealed, not before. A solicitor-drafted separation agreement that is never court-approved does not qualify.
Do I pay stamp duty when I buy out my ex-spouse's share?
It depends on the structure. If the buyout is entirely contained within a court order (i.e., the order directs the transfer and all financial arrangements are part of the settlement), the Schedule 3 exemption may shelter the whole transaction. If you pay cash or take on a larger share of the mortgage to acquire your ex-spouse's share as part of a negotiated deal rather than a purely ordered transfer, chargeable consideration arises and SDLT is assessed on the total: cash paid plus the share of outstanding mortgage assumed. The nil-rate threshold (£125,000 from April 2025) still applies to that consideration.
Is stamp duty payable if unmarried partners transfer property on separation?
Yes, in full. The Schedule 3 court order exemption is only available to married couples and civil partners. Unmarried cohabiting partners who separate and arrange a property transfer between themselves are treated as any other property transaction. SDLT is assessed on the chargeable consideration: cash paid for the equity share plus any share of an outstanding mortgage assumed. There is no court order route to shelter the transfer. If the chargeable consideration is below the nil-rate threshold (£125,000 from April 2025) and no additional property surcharge applies, the tax charge will be zero, but the rules still apply and a return may be needed.
Does mortgage assumption count as chargeable consideration in a divorce transfer?
Yes. When a buyer assumes the seller's share of an outstanding mortgage, they are taking on a debt. HMRC treats that assumed debt as "chargeable consideration" for SDLT purposes, just as if the buyer had paid cash. In a 50:50 jointly owned property with a £300,000 outstanding mortgage, the buying spouse assumes £150,000 of mortgage debt (50% of £300,000) and this £150,000 counts as consideration. If this is within a fully court-ordered exempt transfer, the Schedule 3 exemption may still apply. Where the buyout involves separately negotiated payments, SDLT is calculated on the full amount including the mortgage share.
