Recent UK data reveals a significant surge in legal challenges to estates, with caveat applications to block a Grant of Probate increasing by 56% in the five years leading up to 2024, reaching a record 2,879 applications in the third quarter of 2024 alone. This boom is driven by an ageing population, complex family structures, and a rise in potentially flawed homemade wills. For anyone considering challenging a Will, it is crucial to act within the first six months after the Grant of Representation is issued, as this is the strict statutory deadline for making a claim for reasonable financial provision under the Inheritance Act 1975.

The New Reality: Why Probate Disputes Are Soaring
The dramatic rise in contesting cases is not accidental. It is the result of several intertwined societal and financial pressures that have coalesced in the mid-2020s:
1. The Great Wealth Transfer and Property Values
The most fundamental driver is financial. High house prices have inflated the value of family estates, meaning the financial stakes in any dispute are much higher than they were a decade ago. When assets are valuable, beneficiaries are naturally more motivated to ensure the distribution is fair and lawful.
2. The Rise of Complex Family Dynamics
Modern families are often blended, involving second marriages, step-children, and cohabiting partners. The traditional nuclear family structure is no longer the norm, and Wills must navigate complex webs of loyalty and expectation. This complexity fuels disputes when a Will prioritises one branch of the family over another, particularly if a homemade Will fails to legally accommodate all dependents.
3. The Time Bomb of Homemade Wills and Capacity Issues
With the rise of low-cost DIY Will kits, more Wills are being drafted without professional legal oversight. These documents are prone to technical errors (such as incorrect witnessing) or ambiguous language, making them much easier to challenge on the grounds of lack of due execution.
Furthermore, as the population ages, concerns over the deceased’s mental capacity at the time the Will was signed are becoming far more common. A surge in diagnoses of conditions like dementia means that medical evidence is now central to most challenges.
The Battle for the Grant of Probate: A 56% Surge in Conflict
The clearest indicator of the conflict facing UK families is the staggering increase in the number of caveat applications.
A Caveat is a simple, inexpensive legal tool that stops the Grant of Probate from being issued, pausing the Executor’s authority. It is the essential first step in challenging a Will. The figures speak for themselves:
- Data Alert: Freedom of Information (FoI) data revealed a massive 56% increase in applications to block a Grant of Probate in the five years leading up to 2024. The third quarter of 2024 alone saw a record high of 2,879 caveat applications.
This extraordinary surge shows that thousands of families every month are proactively stepping in to pause the probate process because they have serious concerns about the Will’s validity (due to influence, capacity, or fraud) or because they intend to make a claim against the estate.
The message is clear: the moment you suspect an issue with a Will, you must act immediately to stop the Grant of Probate using a Caveat (a preventative measure used before probate is granted, it stops the process temporarily while disputes are reviewed). This action protects the estate from being distributed while your claim is being prepared.
The Critical Window: Why the First Six Months Are Non-Negotiable
The high volume of disputes makes the issue of timing the most critical factor in contentious probate. You cannot afford to wait.
While lodging a Caveat provides protection against immediate distribution, there is a fundamental statutory deadline that you must respect, particularly if you are making a claim because you were unfairly excluded:
The Six-Month Inheritance Act Deadline
If you are a spouse, partner, dependent, or child making a claim for reasonable financial provision because the Will (or the rules of intestacy) failed to provide for you, the law imposes a strict deadline.
You must issue your claim in court within six months of the date the Grant of Representation (Probate or Letters of Administration) was issued.
- The Risk of Delay: Missing this six-month window can be catastrophic. The court has the discretion to allow late claims, but it is extremely rare, particularly if the delay is long and the estate has already been partially distributed.
- The Power of Early Action: By engaging a specialist solicitor immediately, you ensure your case is fully prepared and ready to file on time, giving you the best possible chance of a successful outcome.
The six-month period is a non-negotiable legal boundary. When dealing with an unjust Will, waiting only serves the interests of the party you are challenging. For further details, read our guide: Contest a Will After Probate Has Been Granted
What This Means for Beneficiaries and Families
The boom in Will disputes is not a negative trend for justice; it is a reflection of people fighting back against perceived unfairness.
For families facing this challenge, this data provides two crucial takeaways:
1- You are not alone: The complexity you face is now commonplace, and expert legal help is readily available.
2- Act Now, Act Decisively: Given the speed at which Executors now apply for probate, your primary focus must be on lodging a Caveat immediately, followed by securing legal advice to confirm your grounds for challenging the Will or making a claim.
The increased wealth and complexity that drives this surge mean that the stakes are higher than ever. When facing a potentially unjust Will, you need a compassionate expert who is familiar with the current legal landscape and the latest trends in probate disputes.
Do not let anxiety or the complexity of the law prevent you from asserting your rights. The rise in contested Wills proves that securing justice for your loved one and yourself is a necessary and achievable goal.
Conclusion: Securing Justice in a Complex Era
The surge in UK probate disputes is a powerful indicator that the Wills being executed today are not always fit for the purpose of transferring modern wealth across complex families. With 2,879 caveats being lodged in a single quarter, the fight for fair inheritance is happening now.
If you have concerns about a Will’s validity, or if you feel you have been unfairly excluded, your time to act is limited and critical. Do not let the probate process race ahead.

FAQs
1. Why is mediation highly recommended in contentious probate cases, and what if the other side refuses?
Mediation is highly recommended because contentious probate disputes often involve family members, making the emotional and financial cost of a full court trial devastating. Mediation is a confidential, flexible process with a neutral third-party expert designed to reach a bespoke settlement quickly and cost-effectively. Furthermore, the UK Civil Procedure Rules strongly encourage mediation; if the opposing party unreasonably refuses to mediate, a court may penalise them by making an adverse costs order, even if they ultimately win the substantive claim.
2. What steps can be taken if the Will-maker had already been diagnosed with dementia or Alzheimer’s?
A diagnosis of dementia or Alzheimer’s does not automatically invalidate a Will; it merely raises a red flag regarding Testamentary Capacity. The key legal test is whether the Will-maker possessed “sound mind, memory, and understanding” at the time they signed the Will. If this is a concern, your solicitor would immediately seek all relevant medical records and witness statements from the GP, care providers, and the solicitor who drafted the Will (if applicable), to determine if the legal test for capacity was met. This evidence is critical to any successful challenge.
