It’s a familiar scene in films and TV dramas: the family gathered in a wood-panelled office for the reading of a will, only for stunned silence (or heated arguments) to follow when the inheritance isn’t what anyone expected.
But while Hollywood may exaggerate, disputes over wills and estates, known as contentious probate, are increasingly common in real life. Rising property prices, blended families, and complex financial arrangements mean more estates are being challenged.
So, what does contentious probate actually mean, and in what situations might you have grounds to contest a will?
Contentious probate refers to disputes about how a deceased person’s estate is administered. While some disputes are based on technicalities in the drafting or execution of a will, others stem from family circumstances where someone has a legitimate claim for financial provision. This can involve:
Evidence needed to contest a will can include:
Even if the will itself is valid, you might still have grounds for a claim under the Inheritance (Provision for Family and Dependants) Act 1975.
The Inheritance Act allows certain individuals to apply to the court if they believe they haven’t been left “reasonable financial provision.” A key ruling is the real-life case of Ilott v Mitson. A mother left her entire estate to several charities, excluding her estranged daughter of 26 years. The daughter successfully claimed under the Inheritance (Provision for Family and Dependants) Act 1975, eventually being awarded £50,000 by the Supreme Court. It was a landmark case that showed how the courts balance testamentary freedom with fairness for dependants.
You may be eligible if you are:
These claims can apply whether there is a will or the person died without one (intestate).
In practice, most contentious probate disputes don’t go all the way to a trial. Not only are court cases stressful and costly, but they can also cause lasting damage to family relationships.
That’s why courts encourage Alternative Dispute Resolution (ADR), particularly mediation. In mediation, a neutral mediator helps the parties negotiate a settlement. It’s confidential, often quicker, and usually less expensive than a court hearing. Importantly, if mediation is successful, the resulting agreement is binding.
If ADR fails, the dispute may still need to be decided in court, but the preference is always to resolve matters amicably where possible.
It’s crucial to act quickly. Claims under the Inheritance Act must usually be issued within six months of the Grant of Representation being issued.
That means if you think you may have a claim, you should seek legal advice without delay.
In probate disputes, the general rule is that the losing party pays the winner’s legal costs. In some cases, costs may come from the estate, but this is not guaranteed. Courts have wide discretion and will consider the conduct of all parties when making cost orders.
This is another reason why early advice and a pragmatic approach to settlement can be so valuable.
