Colorado law allows you to complete a medical durable power of attorney without witnesses or notarization, although some people still add them. The key is that you sign it and clearly designate your agent and any limits. The state health department explains that you can complete the form at home and share it with your agent and providers. Using witnesses or a notary can help with recognition in other states. Keep copies accessible and tell your healthcare team it exists. These instructions come from Colorado’s MDPOA statute and public health guidance.
