A will regulates how your assets are to be distributed when you die. Through a will you can change the current inheritance rules. A child always has the right to its statutory share of inheritance, which is half of the distributive share of the estate. In the event of a death the surviving spouse is also entitled to his/her right to marital property, and a surviving cohabiting partner has the right to his/her cohabitation property. It is particularly important to write a will if you or your spouse has a child from a previous marriage, i.e. a child that is not your joint child. This is because a child from a previous marriage is entitled to its inheritance immediately after the death of the parent.
