The first step to getting power of attorney over an elderly parent is to research powers of attorney, understand how these documents work in your state and the scope of available powers. Talk to your parent so they understand why you want to take this step and the benefits and drawbacks of the action. Consult a lawyer who can help you draw up a document that details your parent’s rights and the agent’s responsibilities, whether that’s you or another person. Finally, execute the document by getting all parties to sign it and have it witnessed as required by state law.
