What are probate claims?
Probate is the legal process of dealing with someone’s estate after they die. This can include identifying assets, paying debts, dealing with tax, applying for a Grant of Probate or Letters of Administration, and distributing the estate to those entitled to inherit.
A probate claim is a legal dispute arising from that process; such claims are often referred to as Contentious Probate matters.
The Economist recently reported that the number of probate claims listed at the High Court has grown by more than 400% over the past decade, citing data from the legal analytics company Solomonic. It also reported that the first three months of 2026 saw the highest number of probate claims filed in any quarter on record.
Public data from Solomonic also points to a clear upward trend: its analysis described 2025 as another record-breaking year for probate disputes, with new probate claims issued in 2025 up 13% on 2024 and the final quarter of 2025 recording the highest quarterly volume of the decade to date.
The Financial Times has also reported that more than 1,200 probate lawsuits were filed at the High Court in 2025, a rise of 13% from the previous year, with Solomonic data showing 342 claims issued in the final three months of 2025 alone.
These figures show only claims that reach the High Court; many inheritance disputes are resolved earlier through correspondence, negotiation or mediation, so the true number of families affected is likely to be much higher.

What is contentious probate?
Contentious probate is the term used for legal disputes over someone’s estate after they have died. These disputes may involve the validity of a Will, how the Will should be interpreted, who should administer the estate, whether an executor has acted properly, or whether someone should have received financial provision.
If a dispute has already started, early legal advice can help clarify where everyone stands. This may include assessing whether there are grounds to challenge a Will, how to respond to a claim, what executors should do next, or whether the dispute can be resolved without going to Court, for example through mediation or negotiation.
Not every case needs to go to Court. Many disputes can be resolved through correspondence, negotiation or mediation. Where Court proceedings are necessary, specialist advice can help protect a client’s position and manage the process properly.

TLW Solicitors’ comment
“This reported rise in probate claims is a reminder that inheritance disputes are becoming increasingly common. Families are often dealing with more complex circumstances, including second marriages, blended families, rising property values and relatives who may have different expectations about what they should receive.
When a Will is unclear, out of date, homemade or missing altogether, those tensions can become much harder to resolve after someone has died. What starts as a question about who should inherit, or how an estate should be dealt with, can quickly escalate and become a costly, time consuming and stressful legal dispute.
Proper estate planning cannot prevent every disagreement, but a professionally drafted Will, clear records and early advice can significantly reduce the risk. Where a dispute has already arisen, getting advice at an early stage can help families understand whether there is a legal claim and whether the matter can be resolved without going to Court.”

Why do inheritance disputes happen?
Probate disputes can arise for many reasons.
Common causes of inheritance disputes include:
- no valid Will
- a homemade, DIY or AI-generated Will with unclear wording
- concerns about whether the person had capacity when the Will was made
- allegations of undue influence or coercion
- disagreement between siblings, stepchildren, partners or wider family members
- disappointment about who has inherited
- claims by someone who believes they should have received financial provision
- concerns about how executors are dealing with the estate
- delays in administering the estate
Modern family structures can also complicate inheritance: second marriages, unmarried partners, children from previous relationships and stepchildren can all create issues if a Will has not been properly prepared or kept up to date.
Rising property values may also mean that estates are worth more than expected, increasing the likelihood of disagreement where family members feel they have been treated unfairly.

Why properly drafted Wills are vital
A properly drafted Will can reduce the risk of confusion after death. It should set out who inherits, who will act as executors, and how specific assets should be dealt with. It can also help address more sensitive issues, such as excluding someone from a Will, making provision for a vulnerable beneficiary, protecting children from a previous relationship, or setting up Trust arrangements.
A Will should be reviewed after major life changes, including marriage, divorce, the birth of children, the death of a beneficiary or executor, a property purchase, or a significant change in financial circumstances. Where a Will is unclear, out of date or not legally valid, the estate may not pass in the way the person intended. In some cases, family members may need to take legal advice or bring Court proceedings to resolve the dispute.

How can families reduce the risk of an inheritance dispute after death?
There is no way to remove every risk of disagreement, but practical steps can help.
These include:
- having a professionally drafted Will
- reviewing it regularly
- choosing suitable executors
- keeping clear records of decisions and intentions
- taking medical advice where capacity may be questioned
- avoiding informal promises that are not reflected in the Will
- considering whether anyone may have a claim against the estate
