Key Takeaways
- You may have a claim where inheritance tax advice formed part of the retainer, the solicitor breached their duty, and that breach caused loss.
- A potentially exempt transfer becomes exempt only if the donor survives seven full years. Otherwise, the gift enters the inheritance tax calculation.
- Your claim must show that proper advice would probably have changed the gift, for example by delaying it, reducing it or using exemptions.
- Check whether continued use of a gifted home, capital gains tax or missing valuations created further avoidable financial consequences.
- Gather the engagement letter, file notes, correspondence, gift records and valuations to establish the advice, its scope and the resulting loss.
- Professional negligence claims generally allow six years from breach or three years from knowledge, subject to a 15-year long-stop.
- Our solicitors can assess duty, breach, causation and recoverable loss, including tax that proper lifetime-gift advice could have avoided.

Can You Claim If a Solicitor Failed to Explain the IHT 7-Year Rule?
You may have a professional negligence claim if a solicitor failed to explain the inheritance tax (IHT) 7-year rule on a lifetime gift. Four conditions must be met: the advice fell within the solicitor’s retainer, it fell below a reasonable professional standard, correct advice would probably have changed the gift, and a financial loss resulted.
An unexpected inheritance tax bill does not prove negligence on its own. The first question is always what the solicitor was instructed to do. They may have been asked to advise on the tax consequences of the gift or on estate planning generally. They may also have handled a transaction that clearly called for tax warnings.
Our London-based solicitors regularly review engagement letters, correspondence, gift records and valuations when assessing professional negligence claims of this kind.
Was Inheritance Tax Advice Within the Solicitor’s Retainer?
Inheritance tax advice is within the retainer if the client’s instructions, expressly or by clear implication, required the solicitor to address the tax consequences of the gift. The retainer is the agreement that defines the solicitor’s work. It may appear in an engagement letter, terms of business, emails, attendance notes, draft documents and billing records.
Relevant questions include:
- Did the client ask about reducing inheritance tax?
- Did the solicitor discuss estate planning, lifetime gifts or passing assets to children?
- Did the solicitor present themselves as experienced in tax or estate planning?
- Did the solicitor prepare the documents that put the gift into effect?
- Was an accountant, tax adviser or financial planner separately instructed?
- Did the solicitor say that specialist tax advice was needed?
A separate tax adviser may narrow the solicitor’s responsibilities, but it does not automatically remove them. The documents should show who was responsible for explaining each tax consequence.
What Advice Would a Competent Solicitor Have Given About a Lifetime Gift?
A competent solicitor advising on a lifetime gift should ordinarily explain that an outright gift may be a potentially exempt transfer (PET), which becomes exempt from inheritance tax only if the donor survives seven full years from the date of the gift. The advice should also cover whether the donor will keep any benefit from the asset, whether any exemptions apply, and whether the arrangement creates other tax or practical risks.
Common failures in lifetime-gift advice include:
- Not explaining the seven-year survival requirement.
- Not warning about the gift-with-reservation-of-benefit rules.
- Not considering exemptions such as the £3,000 annual exemption, small gifts, wedding gifts or normal expenditure out of income, and the records each requires.
- Not considering capital gains tax.
- Not discussing care-fee consequences.
- Not recording the donor’s reasons and instructions.
- Not obtaining or retaining a reliable valuation.
- Not considering whether a trust or a different structure would better meet the donor’s aims.
Breach is judged against the standard reasonably expected when the advice was given, not with hindsight. A tax charge arising later is not enough. The test is whether a reasonably competent solicitor would, at that time, have identified the risk and given the warning or explored alternatives.
What Should a Solicitor Explain About Potentially Exempt Transfers, Taper Relief and Gifts With Reservation?
A solicitor advising on a lifetime gift should explain three things: how the seven-year rule works, how taper relief reduces tax on a failed gift, and how keeping a benefit from the asset can defeat the gift for inheritance tax purposes.
What Happens if a Donor Dies During the Statutory Survival Period After a Gift?
If the donor dies within seven years, the gift becomes chargeable and is brought back into the inheritance tax calculation. When a PET fails in this way, it is added to other gifts made in the seven years before death. That total is then measured against the £325,000 nil-rate band, and inheritance tax is charged at 40% on the taxable portion, subject to taper relief.
GOV.UK explains the inheritance tax treatment of gifts, including the seven-year rule and taper relief.
How Does Taper Relief Affect a Failed Lifetime Gift?
Taper relief reduces the inheritance tax rate on a failed PET where the donor survives more than three years. It reduces the rate of tax, not the value of the gift.
| Years between gift and death | Rate of tax on the gift |
|---|---|
| 3 to 4 years | 32% |
| 4 to 5 years | 24% |
| 5 to 6 years | 16% |
| 6 to 7 years | 8% |
| 7 or more | 0% |
Taper relief applies only where the total value of gifts made in the seven years before death exceeds the £325,000 tax-free threshold. If the donor dies within three years of the gift, there is no reduction.
Can a Parent Give Away a Home and Continue Living There?
A parent can transfer a home and keep living there, but doing so without paying a full market rent can create a gift with reservation of benefit. The property is then taxed as part of the parent’s estate on death.
Under section 102 of the Finance Act 1986, the reservation rules apply in two situations. The first is where the recipient does not genuinely take possession and enjoyment of the property. The second is where the property is not enjoyed to the entire, or virtually entire, exclusion of the donor and of any benefit to the donor. The relevant period is the seven years ending with death, or the period from the gift to death if shorter.
HMRC’s guidance confirms that property caught by these rules is charged as though it formed part of the donor’s estate immediately before death. In practice, the parent may survive seven years and still gain no inheritance tax benefit from the gift.
How Do I Prove Proper IHT Advice Would Have Changed the Gift?
You prove causation by showing, on the balance of probabilities, that proper advice would have led the donor to take a different course. Causation is often the hardest issue in an inheritance tax professional negligence claim.
The different course might have been:
- Not making the gift.
- Delaying the gift.
- Making a smaller gift.
- Using available exemptions.
- Transferring a different asset.
- Using a trust or protective structure.
- Arranging occupation of a gifted property differently, for example by paying a full market rent.
What Evidence Shows What the Donor Would Probably Have Done?
The most persuasive evidence usually dates from the time of the gift. It can show the donor’s aims, financial position, health and attitude to tax risk.
Useful material includes:
- Emails and letters with the solicitor.
- Attendance notes and draft advice.
- Notes of family meetings.
- Gift deeds and transfer documents.
- Property or asset valuations.
- Bank statements and financial records.
- Medical records, where the donor’s health was relevant to the decision.
- Evidence from relatives, advisers and other witnesses.
- Advice from accountants or financial planners.
Expert evidence from a solicitor experienced in tax and estate planning is usually needed. The expert addresses what advice should have been given on those instructions.
When Can a Solicitor’s Breach Still Fail to Cause a Recoverable Loss?
A claim may fail on causation if the donor would have made the same gift whatever the tax consequences. A donor determined to give a child immediate funds for a house purchase may not have changed anything, even with a full warning.
The claim must also compare the actual result with a realistic alternative. A claimant cannot treat the whole inheritance tax bill as recoverable if tax would still have arisen under the arrangement the donor would probably have chosen.
How Is Compensation Calculated for Negligent IHT Lifetime-Gift Advice?
Compensation is the difference between the inheritance tax actually paid and the tax that would probably have been paid had the donor received and followed proper advice. It is not simply the tax bill.
The calculation may take account of:
- Inheritance tax paid following the failed lifetime gift.
- Any taper relief that applied.
- The available nil-rate band.
- Exemptions or reliefs that should have been considered.
- Tax that would still have been payable under the realistic alternative.
Interest on the tax paid and the costs of dealing with an HMRC enquiry may also be recoverable as consequential losses, subject to proof and mitigation.
Worked Example: A Failed £500,000 Gift
Suppose a donor makes a £500,000 gift and dies four years later, with no other gifts in the previous seven years. The £325,000 nil-rate band is deducted first, leaving £175,000. Applying the 24% taper-relief rate gives an inheritance tax figure of £42,000.
The £42,000 is the starting point, not the value of the claim. Suppose that, properly advised, the donor would have used the £3,000 annual exemption and spread the gift over time. The recoverable loss is then the difference between £42,000 and the tax that the staged arrangement would still have produced.
How Can Agricultural and Business Property Relief Affect the Loss Calculation?
Agricultural Property Relief and Business Property Relief can change the calculation significantly where the gift included qualifying farm or business assets. From 6 April 2026, 100% relief for qualifying agricultural and business property is subject to a combined allowance of £2.5 million per person. Qualifying value above that allowance receives 50% relief.
Gifts of qualifying agricultural or business property made on or after 30 October 2024 count towards the allowance where the donor dies within seven years of the gift and the death occurs on or after 6 April 2026. HMRC sets out the mechanics in its guidance on apportioning Agricultural and Business Relief. Advice on gifts of family businesses or farmland given since late 2024 should have addressed these rules.
How Should a Claimant Mitigate an Inheritance Tax Loss?
A claimant must take reasonable steps to reduce the loss, including claiming available reliefs and exemptions after the donor’s death. A failure to do so may reduce the amount recoverable from the solicitor.
Before treating the full tax bill as the loss, the personal representatives should check whether Business Property Relief, Agricultural Property Relief or other exemptions were properly claimed. If an estate pays tax on gifted company shares without claiming relief that was available, the former solicitor will argue that much of the tax was avoidable through the estate’s own action, and the claim may be reduced accordingly.
What Other Risks Should a Solicitor Address Before Arranging a Lifetime Gift?
Where the instructions covered wider estate planning, a solicitor should have addressed capital gains tax, loss of control over the asset, care-fee consequences and record-keeping, as well as inheritance tax.
Can a Lifetime Gift Create a Capital Gains Tax Liability?
A lifetime gift can create a capital gains tax liability because it is treated as a disposal at market value, even though no money changes hands. The solicitor should have considered whether gift relief (hold-over relief) was available for a qualifying asset. If it was not, the solicitor should have explained the liability, which the donor must fund without any sale proceeds.
Can a Lifetime Gift Leave Assets Exposed to Divorce, Insolvency or Creditors?
A gifted asset can be exposed to the recipient’s divorce, bankruptcy or creditors, because once ownership passes it belongs to the recipient. Where the donor wanted to protect the asset within the family, a protective trust or a different arrangement may have met that objective better than an outright gift.
Can a Gift Affect Care-Fee Assessments and Estate Administration?
A gift intended to reduce care costs may be treated by the local authority as a deprivation of assets and disregarded, so the solicitor should have warned of that risk. Poorly documented gifts also cause problems later. Personal representatives need accurate records of lifetime gifts, their values and any continued benefit to complete the estate’s inheritance tax position correctly.
What Laws and Deadlines Apply to Solicitor Negligence Claims for IHT Lifetime-Gift Advice?
A professional negligence claim against a solicitor is subject to a six-year limitation period, or three years from the date the claimant had the knowledge required to bring the claim where that ends later, subject to a 15-year long-stop. Missing the deadline can bar an otherwise valid claim, so the dates should be checked as soon as a problem is suspected.
Section 14A of the Limitation Act 1980 creates the special period for negligence claims involving latent damage. It provides six years from the date the cause of action accrued, or three years from the statutory starting date where that expires later. Which route applies depends on how the claim is framed and on the facts.
Lifetime-gift cases raise particular timing problems. The advice may have been given many years before the donor’s death, and the tax consequence may only become apparent when the inheritance tax falls due. That does not make delay safe. Files are destroyed, witnesses become unavailable and recollections fade, and each of these weakens the evidence on causation.
How Do I Bring a Professional Negligence Claim Against a Solicitor for IHT Advice?
You bring a claim by preserving the documents, obtaining expert evidence on breach and loss, and presenting a properly evidenced claim to the former solicitor.
How Do I Investigate a Potential Claim Step by Step?
- Obtain the engagement letter, terms of business, invoices, attendance notes and correspondence with the former solicitor.
- Collect the gift documents, title records, valuations, inheritance tax calculations, estate accounts and HMRC correspondence.
- Identify any advice given by an accountant, tax adviser or financial planner.
- Obtain an independent expert opinion from a solicitor experienced in tax and estate planning on the standard of care and the advice that should have been given.
- Work with a tax adviser or accountant to compare the actual inheritance tax result with the realistic alternative that proper advice would probably have produced.
- Present the evidenced claim to the former solicitor. Many professional negligence claims settle before trial, often after experts’ reports are exchanged and the parties hold a without-prejudice meeting.
What Happens if the Former Solicitor Has Closed or Has Professional Indemnity Insurance?
Solicitors carry professional indemnity insurance, so a key early step is to identify whether the firm still practises and which insurer may respond. A closed firm does not necessarily end the investigation. If the firm has closed, the Solicitors Regulation Authority’s compensation fund may be available, subject to limits. The route forward depends on the firm’s status, the timing of the advice and the circumstances of the closure.
Frequently Asked Questions
Speak to a Professional Negligence Solicitor About IHT Advice
A viable claim for failed lifetime-gift advice turns on the retainer, on whether proper advice would have changed the donor’s decision, and on the difference between the tax paid and the tax a realistic alternative would have produced. Limitation deadlines can run even where the inheritance tax liability only became clear after the donor’s death, and evidence weakens with every year that passes.
