If you haven’t made a will already, you should make one. This is separate from your living will, which details what medical treatments you want done. A conventional will tells your family who will get any remaining money, property and other items. If you have specific things you want to leave to specific people, this is the place to put that in writing.
If you already have a family lawyer, he or she can help you with both your will and your health-related documents. A lawyer can make clear what the requirements are in your state. While you do not need to have a lawyer to make a will, a lawyer can make things easier.
