Stamp Duty on Divorce: When Transferring the Family Home Is (and Isn't) Exempt
Transferring property between spouses as part of a divorce or separation is usually exempt from Stamp Duty Land Tax — but the exemption has specific conditions, and getting the timing or paperwork wrong can trigger an unexpected bill.

Divorce and separation settlements very commonly involve exactly this — one spouse keeping the family home and taking over the mortgage, while the other's name comes off the property and the mortgage. Without a specific exemption, this could create an unexpected SDLT bill purely as a consequence of formalising a divorce settlement, which is why HMRC exempts these transfers when they're genuinely connected to the relationship ending.
What Qualifies
| Situation | Exempt? |
|---|---|
| Transfer between spouses under a divorce court order | Yes |
| Transfer between civil partners under a dissolution order | Yes |
| Transfer under judicial separation | Yes |
| Transfer under a settlement agreement made in contemplation of divorce | Generally yes, if genuinely connected |
| Transfer between unmarried cohabiting partners separating | No — ordinary SDLT rules apply |
| Transfer between spouses unrelated to divorce/separation (e.g. general estate planning while still married) | No — this specific exemption doesn't apply; other reliefs may or may not apply depending on circumstances |
Worked Example
A couple divorcing jointly own a home worth £400,000 with an outstanding mortgage of £180,000. As part of the settlement, one spouse transfers their share to the other, who takes on the full £180,000 mortgage alone.
| Without the divorce exemption | With the divorce exemption |
|---|---|
| SDLT potentially due on the mortgage debt taken on (£180,000 falls within taxable SDLT bands) | £0 SDLT due — the transfer is exempt in full |
This is a significant, automatic protection for separating couples, but it depends on the transfer genuinely being connected to the divorce and properly documented.
Keeping the Right Documentation
- Court order (final divorce order, dissolution order, or judicial separation order)
- Consent order or financial settlement agreement referencing the property transfer
- Solicitor's confirmation that the transfer forms part of the divorce settlement
Even where a transfer happens somewhat later than the formal divorce date, this documentation is what supports the exemption if it's ever questioned, so keep it safely with your other divorce paperwork rather than assuming it won't be needed again.
What This Doesn't Cover
- Unmarried couples separating: ordinary SDLT rules apply to any property transfer between them, including any consideration such as mortgage debt taken on.
- Later, unconnected property purchases: once the divorce-related transfer is complete, any subsequent property purchase by either spouse is assessed under normal SDLT rules, including the 3% additional property surcharge if applicable based on their ownership position at that time.
- Property outside the marital settlement: transfers of other property not part of the divorce financial settlement don't automatically benefit from this specific exemption.
