If you die without a will, it means you have died intestate. The intestacy rules state how an estate should be distributed if there is no will. It divides the estate between various relatives and sets out how much each receives.
The law decides how your property and other assets are divided. This causes extra trouble and expense. No account will be taken of your wishes. Distant relatives (or even the state) may benefit instead of those you would have chosen. The law also decides who will look after your estate. It may not be the person you would have chosen yourself. Even if you have no family, it is surely better for you to decide who is to inherit your property. You may wish to say thank you to friends or to benefit your favourite charities. By making a will you can choose the right people to look after your children. You can also see that they are cared for financially in the best way.
