With a will, you can decide how your Assets are shared out to your relatives, to friends, or perhaps to your favourite charity.
You can make sure your partner is provided for if you aren't married or in a civil partnership (as your partner will not inherit automatically).
If you're divorced or if your civil partnership has been dissolved, you can decide whether to leave anything to an ex-partner.
When you make a will, you can appoint an Executor who will take responsibility for distributing your assets according to your wishes.
You can also make sure you don't have to pay more Inheritance Tax than necessary.
