Why should I make a Will? Expand Having a valid, and up-to-date Will is the best way to ensure your loved ones will be looked after in the way you choose. Otherwise, if you die intestate (without a Will), the law decides how your estate is divided. A legacy to a registered charity is free from Inheritance Tax and could reduce your overall Inheritance Tax liability if this applies to your estate. If you have no family and have not made a Will, your entire estate could pass to the Crown and be added to the Treasury’s coffers. So while you might want your closest friend to have all your possessions, the law will not agree if there is no Will.
