- Check who remained a member.
- Check whether changes took effect at the same time.
- Keep the partnership agreement and change records.

Stamp duty when members of a property partnership change
For SDLT, a membership change does not always create a new partnership if at least one person who belonged before the change still belongs afterwards. A gap with only one person can change the answer.
What this rule is about
Property partnerships can change over time, with one person leaving, another joining, or both happening on the same day. These changes can happen quickly.
For SDLT, you need to ask whether this is still the same partnership. The answer can affect how SDLT partnership rules apply to land held for the business.
What the official source says
The legislation says a partnership remains the same for SDLT after a membership change if any person who was a member before the change is still a member after it. That person provides the link.
HMRC’s manual adds an important point. There must still be more than one partner.
Its manual is guidance, not law. But it explains HMRC’s view of this situation.
- A member can leave without ending the partnership for SDLT.
- A new member can join without creating a new partnership.
- At least one person must be a member both before and after the change.
- HMRC says a partnership cannot exist with only one member.
What this means in practice
You need to look at the sequence, not just the member lists at the start and end, because if all but one member leave before anyone new joins, the old partnership may end. The order matters.
The paperwork may show changes on one date. Yet the actual documents can set different times.
- If an existing member stays throughout, the continuity rule may apply.
- If all but one member leave before anyone new joins, HMRC says the old partnership ends.
- If a new member joins as others leave at the same time, HMRC says the partnership can continue.
How to analyse it
Start with the membership immediately before and immediately after each change, then trace every event to see whether only one person was a member at any point. Check each step.
- List every member before the change.
- Record who left and who joined.
- Check the date and time of each event.
- Identify a person who remained a member throughout.
- Check whether the partnership agreement continued without a break.
- Keep the documents that show the sequence.
Example
Anna, Ben and Chloe run a property partnership. Ben and Chloe leave.
If Ben and Chloe leave Anna alone, HMRC says that partnership has ended because one person cannot be a partnership. If Daniel joins Anna later, Anna and Daniel form a new partnership.
The result can differ if Daniel joins under the same agreement at the same time that Ben and Chloe leave. Anna remains throughout. There are always at least two members. HMRC says the partnership can then continue.
Why this can be difficult in practice
“At the same time” can be the hard part.
The source gives the principle, but it does not say how to settle unclear facts where people signed documents separately or made them take effect at different times. That can decide the result.
- People often check only the first and final member lists.
- A same-day change is not always a simultaneous change.
- The agreement may need careful reading to establish when membership changed.
Key takeaways
- One continuing member can preserve the partnership’s SDLT identity.
- A period with one member may end the old partnership.
- Dates, times and partnership documents can decide the result.

Legislation
- FA 2003 Schedule 15 para 3 — when a partnership remains the same for SDLT
Official guidance
The pages below are HMRC’s guidance. Guidance is not law. It sets out how HMRC reads the legislation, and it is not binding on you, on a tribunal or on a court. Where guidance and the legislation differ, the legislation wins. HMRC can also change or withdraw guidance, and it may not cover your facts.
Where this is not settled
- The source does not explain how to decide whether changes happened at exactly the same time where documents or events are unclear.
- The source does not address every form of partnership or every wider SDLT consequence of a membership change.
Evidence you would need
This kind of case is decided on the facts of the individual property. These are the records that usually settle it, and the ones an adviser would ask you for.
- The partnership agreement and any amendments
- Records showing when each member joined or left
- Documents showing whether there was any period with only one member
