If you make a valid will, and keep it updated as your circumstances change, you’ll be getting a say in how your assets and estate are divided upon your death. However, if you’re thinking of purposefully disinheriting a spouse, a child or someone who is financially dependent upon you, such as a partner or ex-spouse, it’s wise to be aware that they could still make a claim on your estate under the Inheritance (Provision for Family and Dependants) Act 1975.
