Consent forms are legal documents used to obtain a person's permission or agreement to participate in a particular activity, such as a medical procedure, research study, or contractual agreement. The purpose of a consent form is to provide information to the person about the activity or procedure they are agreeing to, including the risks, benefits, and alternatives, so that they can make an informed decision about whether or not to participate. In the medical context, a consent form might outline the risks associated with a particular treatment or surgery, as well as the possible benefits and alternatives. In the context of a contractual agreement, a consent form might outline the terms and conditions of the agreement and require the signer to acknowledge that they have read and understand the terms.
