Did you know that minors who are 15 years old can consent to a variety of medical services without consent from a parent or legal guardian (ORS 109.640). 109.640). Little known fact by a lot of parents, so I put together few links for you to check out if you want to know what your teen can consent to without your knowledge.
Please feel free to take a look at these links.
Please also note that there may have been changes to this area of law since each of these summaries were published.
