SDLT Changes: Ignoring Interests in Former Homes Post-Divorce for Higher Rate Calculation

When a share in a former home can be ignored for SDLT higher rates after separation

If you are divorced or ending a civil partnership and still legally own part of your former home, that interest may be ignored when checking the SDLT higher rates on a new home purchase. This applies to purchases on or after 22 November 2017 where the former home is no longer your main residence, it is the other person’s main residence, and your retained interest is held under a qualifying court order or suitable consent order.

• The rule is aimed at people who have separated but still keep a legal interest in the former family home for family law reasons.
• Your retained interest can be ignored only if the former home is not your only or main residence and is the other person’s only or main residence.
• The interest must be subject to a qualifying property adjustment order, or a court consent order covering the same type of arrangement.
• This exception applies only to purchases completed on or after 22 November 2017; before that date, the interest would usually still count.
• Ignoring this one interest does not automatically remove the higher rates, because any other dwellings or property interests you own still need to be considered.
• In practice, the main issues are whether the court paperwork qualifies and whether the former home is clearly no longer your main residence.

When an interest in a former home is ignored for the SDLT higher rates after divorce or civil partnership dissolution

This page explains a specific exception to the SDLT higher rates for additional dwellings. It matters where someone has separated from a spouse or civil partner, still legally owns a share in the former home, and is buying a new home to live in. In some cases, that retained interest is ignored when deciding whether the higher rates apply.

What this rule is about

The SDLT higher rates can apply when a buyer purchases a dwelling and, at the end of the day of the transaction, they own more than one dwelling or have a major interest in another dwelling. One of the key tests is often called Condition C.

A problem can arise on divorce or dissolution. A person may no longer live in the former family home, but may still have a legal interest in it because a court order requires that interest to remain in place for a period. Without a special rule, that retained interest could cause the purchase of a new home to be treated as an additional dwelling purchase.

The source material explains that, for purchases on or after 22 November 2017, certain retained interests in a former home are ignored for higher rates purposes.

What the official source says

HMRC’s manual says that, from 22 November 2017, a major interest in a dwelling is ignored for the higher rates if all of the following apply:

• the dwelling is not the purchaser’s only or main residence,
• the dwelling is another person’s only or main residence, and
• the purchaser’s major interest in that dwelling is subject to a relevant property adjustment order in favour of that other person.

The manual lists the court orders that count. These are property adjustment orders made under specified provisions dealing with divorce, overseas divorce, dissolution of civil partnership, and overseas dissolution. The list covers England and Wales, Northern Ireland, and civil partnership legislation.

The manual also explains that where a separating couple settle matters by agreement and obtain a consent order from the court, that consent order can satisfy the rule if it deals with matters that would otherwise have been covered by a property adjustment order.

Before 22 November 2017, HMRC says that an interest of this kind would normally still count when testing Condition C.

What this means in practice

If you have separated and are buying a new home to live in, the fact that you still own an interest in the former home does not automatically mean the higher rates apply.

The key point is that the retained interest may be left out of account if it exists because of the kind of court-backed family law arrangement described in the manual.

In practical terms, this exception is aimed at situations where:

• your former spouse or civil partner remains living in the old home as their only or main residence,
• you no longer treat that property as your only or main residence, and
• your continuing ownership position is governed by a qualifying court order or equivalent consent order.

If those conditions are met, that former-home interest is ignored when considering whether your new purchase is caught by the higher rates.

This can be important because many separating couples do not immediately transfer the former home outright. Instead, one party may remain on the title until children reach a certain age, until remarriage, or until another trigger event. The rule recognises that this kind of retained interest may exist for family law reasons rather than because the buyer is building a property portfolio.

How to analyse it

A sensible way to approach this issue is to ask the following questions.

• Is the purchase taking place on or after 22 November 2017? If not, this particular exception does not apply.
• Do you still hold a major interest in the former home? The rule only matters if you do.
• Is that former home still your only or main residence? If it is, this exception is not aimed at that situation.
• Is the former home the only or main residence of the other person, such as your ex-spouse or ex-civil partner?
• Is your retained interest subject to a qualifying property adjustment order, or to a consent order that covers the same kind of matters?

If the answer to all of those questions is yes, the manual indicates that the retained interest is ignored for higher rates purposes.

You should also keep in mind what this rule does and does not do. It does not say that the whole transaction is automatically outside the higher rates in every case. It says that this particular major interest is ignored when applying the higher rates test. If the buyer owns other dwellings or interests, those may still matter.

Example

Illustration: A divorcing couple agree that the husband will remain in the former family home with the children until the youngest child turns 18. The wife keeps a legal interest in that property, but the arrangement is formalised by a court consent order dealing with the property in the same way a property adjustment order would.

Later, the wife buys a new house to live in as her own main residence. On these facts, the retained interest in the former family home is ignored for the SDLT higher rates test, because:

• the former home is no longer her only or main residence,
• it is the husband’s only or main residence, and
• her retained interest is covered by the relevant court order framework.

This example reflects the effect described in the HMRC manual.

Why this can be difficult in practice

The main difficulty is often not the broad idea, but whether the legal paperwork fits the rule.

For example, it may not always be obvious whether an arrangement is properly evidenced by a qualifying order, especially where parties reached an agreement themselves and only later asked the court to approve it. HMRC’s manual says a consent order will satisfy the test where it deals with matters that would otherwise have been the subject of a property adjustment order, but the exact terms of the order may still matter.

Another fact-sensitive issue is residence. The rule depends on the former home not being the purchaser’s only or main residence, but being another person’s only or main residence. That can be straightforward where one person has clearly moved out and established a new home, but less straightforward if occupation is mixed or transitional.

It is also important not to overread the rule. It only addresses the treatment of a retained interest in a former home in this specific family law context. It does not replace the wider higher rates analysis, and it does not mean all post-separation property interests are ignored.

Key takeaways

• For purchases on or after 22 November 2017, a retained interest in a former home can be ignored for SDLT higher rates purposes after divorce or civil partnership dissolution.
• The exception depends on the former home being someone else’s only or main residence and the retained interest being subject to a qualifying court order or suitable consent order.
• This rule removes one specific interest from the higher rates test; the rest of the buyer’s property position still needs to be checked.
