A Will Is Not The Final Word On Your Estate

I sat with a family recently. The father had died five years before. He left a will stating his son, who lived in and maintained the family home, was to receive the entire estate. His daughter, from whom he was estranged, was left a nominal amount. Now, the son has finally started the probate process to transfer the house to his name. Within weeks, a letter arrived from his sister’s solicitors. She is contesting the will.

His lawyers are advising him to settle. He wants to go to court. He has witnesses to the poor relationship between his sister and their father. He feels his case is watertight. He is right to feel aggrieved. But the reality is that going to court will cost him between £50,000 and £100,000 in legal fees, with no guarantee of success. The equity in the home he is trying to protect will be used to fund the fight.

Where It Goes Wrong

This is not an American problem. It happens here, every week. The core issue is a piece of UK legislation: the Inheritance (Provision for Family and Dependants) Act 1975. This Act allows a child, spouse, or dependant to make a claim against an estate if the will does not make ‘reasonable financial provision’ for them. A judge has the power to ignore the deceased’s wishes and re-allocate assets.

The father’s will was clear. But clarity is not a sufficient defence. His daughter’s legal team will argue that, regardless of the relationship, she was a child of the deceased and he had a moral obligation to provide for her. The son’s emotional desire for justice is running headfirst into the cold, financial reality of a legal challenge. The system is not designed to rule on who was right or wrong. It is designed to rule on whether the provision was reasonable.

A Letter is Not Enough

The key planning implication for UK families is this: you cannot simply write a child out of your will and expect that to be the end of the matter. We advise clients to prepare a separate, non-binding Letter of Wishes to sit alongside the will. This document is not legally binding, but it sets out, in your own words, the detailed reasons behind your decisions. It gives a judge context for why you chose to exclude someone, strengthening the position of your executors.

For high-value assets like a property, placing it into a lifetime trust can remove it from your estate entirely, offering a far higher degree of certainty and protection from this kind of claim. These are difficult conversations. We have them every week. If this is on your mind, the first step is to talk.
