Wills need to be in writing, including your name, address and marital status. The terms of the will need to include a statement of which property you want to be distributed to which beneficiaries. It also needs to specify who you want to serve as your executor. That is the person who will have the power to carry out the terms of your will. If you have minor children, you should also include the name of the person you want to serve as their guardian, should anything happen to you and there is no surviving parent.
