What are the important factors when considering plastic surgery from a legal perspective?

I am considering plastic surgery and am curious about the legal precautions I should take. I would like to know what information should be included in the surgery contract or consent form, and how to verify if the hospital employing me is trustworthy. I would also like to know how to legally respond if problems arise after the surgery. If anyone has experience with this, I would be grateful if you could share any relevant information or advice.
