1. by voluntary relinquishment (putting your child up for adoption). 2. state can take child away (must have showing the bio parent is unfit. burden of proof is clear and convincing evidence, can be appointed counsel if you can't afford). Grounds: 1. abuse, 2. abandonment, failure to communication, 3. neglect (sad stuff), 4. failure to pay child support for period of time, 5. severe mental illness/drug addiction. parents must consent to adoption unless their rights have been terminated, also need consent of child. if someone else has custody, need their consent too. adoption cannot be undone.
