How old do you have to be to emancipate from your parents?

If you had read some of the other questions, you would have learned that it's not particularly about age. It's about the minor being able to act as, be treated as, and be responsible as an adult. Being pregnant or having a girl pregnant is probably not in your favor, neither would a criminal or traffic record.

Generally you will need to be able to care for yourself including paying rent, paying bills and having insurance or money for adequate medical care.
