If you are not able to make certain decisions on your own, you can make a co-decision-making agreement. This agreement lets you choose someone you know and trust, such as a friend or family member, to be your co-decision-maker. In the agreement, you write down decisions you need help with and give someone the legal authority to make those decisions jointly with you. They will help you to gather information and explain it to you in a way that you understand. They can also help you to let other people know about the decision you have made together.
