Informed Consent
Informed consent means you must be told about the risks, benefits, and alternatives of a medical procedure or legal action, and then voluntarily agree to it, before it can go forward.
What it actually is
Informed consent is a legal doctrine requiring that a person receives clear, material information about a proposed action—such as a medical treatment or participation in a trial—and that the person’s agreement is given freely and with understanding. It most often appears in medical malpractice or battery cases, where the plaintiff argues that the defendant failed to disclose key facts before proceeding. It can also arise in contract or criminal defense contexts when a defendant claims they agreed to something without full knowledge.
Why it matters in your case
If you are a defendant in a case involving informed consent, the plaintiff must prove that you did not provide enough information for them to make a meaningful choice, which can shift the burden to you to show you did. If you are a plaintiff, you must show that you would not have consented had you known the undisclosed risk, making this issue central to both liability and damages.
The common misunderstanding
Many people think informed consent is just signing a form, but it is the process of communication that matters, not the signature itself. Consent is not “informed” if the person did not understand the information given, even if they signed a document.

Definitions are orientation; rules are authority
This page explains the concept. When it matters to your case, read the rule that governs it in your court — we hold Texas, federal and Washington court rules word for word, and every state's official resources are on the state pages. If someone cites a case at you, check that it exists first.
