When a will feels wrong, families often know it before they know the legal reason. You may have been left out unexpectedly, seen a sudden change made late in life, or worried that someone vulnerable was pressured into signing. If you are asking, can I challenge a will, the answer may be yes – but only in certain circumstances, and timing matters.
Challenging a will is not simply about whether the outcome feels unfair. In England and Wales, a will can only be disputed on recognised legal grounds. That is why early advice is so important. The right solicitor can help you work out whether you have a valid claim, what evidence may be needed, and whether court proceedings are likely to be the best route.
Can I challenge a will if I think it is unfair?
This is one of the most common questions we hear, and the honest answer is: it depends on why it seems unfair.
A person making a will is generally free to leave their estate to whoever they choose. That can come as a shock to close relatives who expected to inherit. Being disappointed, or even surprised, is not by itself enough to overturn a will. However, if there are concerns about how the will was made, or if someone who depended on the deceased has not been reasonably provided for, there may be legal options.
In practice, disputes usually fall into two broad categories. The first is a challenge to whether the will is legally valid at all. The second is a claim against the estate, even where the will itself is valid. The distinction matters because the legal tests, time limits and evidence can be very different.
Grounds to challenge a will
A will may be challenged if there is a proper legal basis to do so. Some of the most common grounds include lack of testamentary capacity, undue influence, lack of knowledge and approval, fraud or forgery, and problems with the way the will was signed and witnessed.
Lack of testamentary capacity
The person making the will, known as the testator, must understand what a will is, what they own, and who might reasonably expect to benefit. They must also be free from a mental disorder that affects their decision-making in relation to the will.
This issue often arises where the deceased had dementia, severe illness, confusion caused by medication, or other cognitive problems. A diagnosis alone does not automatically make the will invalid. What matters is capacity at the time the will was made. Medical records, solicitor attendance notes and witness evidence can all be important here.
Undue influence
Undue influence means pressure that overpowers the will of the person making it. Not all persuasion counts. Family members often discuss wills, and people do change their minds. The problem arises when someone is coerced, manipulated or frightened into leaving their estate in a way they did not truly choose.
These cases can be difficult to prove because pressure often happens behind closed doors. A sudden change to a long-standing will, isolation from family, dependence on one person, or suspicious circumstances can all raise concern, but each case turns on its own facts.
Lack of knowledge and approval
Even if a person had mental capacity, the will may still be challenged if they did not truly understand or approve its contents. This may happen if the document was prepared in a way that did not reflect their wishes, or if they signed something without appreciating its effect.
This ground can be relevant where a will was read poorly, explained inadequately, or prepared by someone who stood to benefit from it.
Fraud or forgery
If a signature has been forged, or the deceased was deliberately misled into signing a document, the will can be challenged. These allegations are serious and require strong evidence, but they do arise.
Improper execution
For a will to be valid, it usually must be signed by the testator in the presence of two witnesses, who must also sign it properly. If those formalities were not followed, the will may fail.
Claims for reasonable financial provision
Sometimes the real issue is not whether the will is valid, but whether it leaves a dependant without reasonable support. In those cases, a claim may be made under the Inheritance (Provision for Family and Dependants) Act 1975.
This type of claim may be available to a spouse, civil partner, former spouse in some circumstances, children, someone treated as a child of the family, or a person who was being maintained by the deceased.
These claims are especially important where a husband, wife, partner or child has been left with too little to meet their needs. The court looks at a range of factors, including financial resources, obligations owed by the deceased, the size of the estate, and the needs of other beneficiaries. It is not automatic, and not every disappointed relative will qualify.
Who can challenge a will?
Not everyone can bring a claim simply because they disagree with the will. Usually, the person challenging it must have a legal interest in the estate. That may include a beneficiary under the current will, someone who benefited under an earlier will, a person entitled under the intestacy rules if there were no valid will, or someone eligible to claim reasonable financial provision.
This is one reason early legal advice matters. Before costs are incurred, it helps to know whether you are in a position to bring a claim at all.
Time limits matter more than many people realise
If you are wondering can I challenge a will after probate has been granted, the answer is often yes, but delay can make matters much harder.
For claims under the Inheritance Act, the usual time limit is six months from the date of the grant of probate or letters of administration. That is a strict deadline, although the court can allow late claims in limited circumstances.
For validity challenges, the position is less straightforward, but waiting is still risky. Once estate assets have been distributed, recovering them can become far more complicated. If there is a real concern, solicitors can sometimes enter a caveat to stop probate being granted while matters are investigated.
What evidence helps when challenging a will?
Strong cases are built on evidence, not suspicion alone. The right evidence depends on the ground of challenge, but common examples include medical records, previous wills, witness statements, solicitor file notes, handwriting evidence, and correspondence showing the deceased’s intentions.
Family members often have a genuine sense that something was not right, and that instinct should not be dismissed. Still, a claim will usually need more than family disagreement or mistrust. A solicitor can help separate concern from proof and identify what documents should be obtained quickly.
What to expect if you challenge a will
Many people fear that challenging a will automatically means a long and hostile court battle. Sometimes that happens, but many disputes are resolved through negotiation or mediation before reaching a final hearing.
The first step is usually to review the will, the background, and the available evidence. From there, your solicitor may send a formal letter setting out the basis of the claim and seeking disclosure of relevant documents. If the case has merit, the parties may be able to explore settlement.
Court proceedings may be necessary where the facts are heavily disputed, where one side refuses to engage, or where urgent protection of the estate is needed. There is no single route that fits every family. The right approach depends on the strength of the case, the value of the estate, and the practical aim.
Costs and risks
Will disputes can be emotionally draining, and they can also be costly. It is sensible to ask early about likely legal fees, funding options and the risk of paying the other side’s costs if the claim does not succeed.
That said, doing nothing can also carry a cost, particularly where a vulnerable dependant has been excluded or a suspicious will is allowed to stand unchallenged. A good solicitor will be frank about prospects and proportionate about the next steps.
When should you get advice?
As soon as possible. Even if you are not yet sure whether you want to bring a claim, early advice can help preserve your options and prevent avoidable mistakes. Probate disputes often become harder once documents go missing, memories fade, or the estate is distributed.
At Alfred James & Co Solicitors LLP, we understand that disputes over a loved one’s estate are rarely just about money. They often involve grief, family pressure and difficult questions about what really happened. Clear, practical advice can make the situation feel less overwhelming and help you decide on the best way forward.
If you believe a will may be invalid, or you have been left without reasonable financial provision, trust your instincts and get advice promptly. The law does provide routes to challenge a will, but the strongest position usually belongs to the person who acts early and with the right support.
