Stamp Duty Refund After Divorce or Separation — Your Rights Under SDLT Rules

SDLT and Relationship Breakdown

Property and taxes rarely simplify when a relationship breaks down. SDLT rules have several specific provisions relating to divorce, dissolution of civil partnerships, and separation — some of which provide relief, and some of which can create unexpected charges.

Transfers Between Spouses and Civil Partners

As a general rule, transfers of property between spouses or civil partners who are living together are treated as taking place at no gain/no loss for SDLT purposes — meaning no SDLT is typically chargeable, regardless of the amount of any mortgage assumed. This is because transfers between connected persons (spouses living together) are deemed to occur at market value for stamp duty purposes, but the SDLT charge is mitigated by the spousal exemption.

However, once separation occurs, spouses and civil partners are no longer treated as living together for tax purposes from the end of the tax year in which the separation takes place. This can affect how subsequent transfers are treated.

Court-Ordered Property Transfers — SDLT Relief

Where a court orders a property to be transferred from one separating spouse or civil partner to the other as part of a financial remedy order, a specific SDLT relief applies. The transfer under a court order in connection with a divorce or dissolution is relieved from SDLT, provided it meets the qualifying conditions.

This relief is significant: it means a spouse who receives the former matrimonial home as part of a divorce settlement does not pay SDLT on the transfer, even if they are taking on a substantial mortgage.

To claim the relief, it must be declared on the SDLT return. The relief does not apply automatically.

Buying Out a Former Partner — Where SDLT Applies

Where one partner buys out the other's share of a jointly owned property — for example, paying them cash for their 50% share — SDLT is payable on the consideration paid. If the buyer already owns another residential property, the additional dwelling surcharge may apply to this transaction.

**Example:** A couple jointly own their home worth £400,000. On separation, one party buys out the other's 50% share for £200,000 (50% of value). SDLT applies to the £200,000 consideration being paid. If the buying party will end up owning two properties (the buyout property and another), the surcharge applies.

This is an area where legal and tax advice is particularly important before agreeing the financial settlement.

The Surcharge Refund and Separation

If the surcharge was paid on a purchase made before separation, and the 36-month disposal clock is running, separation can complicate the timing. Where the former matrimonial home has not been sold within the 36-month window, the refund right may be lost — even if the property is "stuck" in dispute during divorce proceedings.

HMRC does not treat divorce proceedings as a reason to pause or extend the 36-month clock. If the disposal is delayed because of legal proceedings relating to the matrimonial home, the surcharge may be unrecoverable. This is an area where specialist SDLT advice in the context of a divorce financial settlement is extremely valuable — the solicitors handling the divorce may not spot the SDLT implications without prompting.

First-Time Buyer Status and Previous Ownership Through a Spouse

If a person was on the title of the matrimonial home during a marriage and is now separated, they have previously owned residential property. They cannot claim first-time buyer SDLT relief on a future purchase, even though the property was their matrimonial home and they may not feel like a "property owner" in a meaningful sense. The law makes no distinction.

Getting Advice

SDLT in the context of relationship breakdown is a genuinely complex area, with multiple reliefs and charges interacting with the family law financial settlement process. Anyone going through a separation that involves property should ensure their family law solicitor coordinates with a specialist SDLT adviser before finalising any property transfer agreement.
