Can a 17-year-old legally move out without their permission if they are still in high school?

In most U.S. states, a 17-year-old cannot legally move out without their parents' permission. While the exact laws vary by state, minors generally don't have the legal right to enter into contracts (like renting an apartment) or support themselves independently. Running away, even if motivated by difficult circumstances at home, is not a legal way to circumvent parental control.

There are very limited exceptions, such as emancipation, which requires demonstrating to a court that the minor is self-supporting and can manage their own affairs. This is a difficult process and rarely granted.

In short, while a 17-year-old *might* physically move out, they would likely be doing so illegally and face legal repercussions, including the possibility of being returned home by authorities. The better course of action would be to explore other options, such as talking to a trusted adult, counselor, or social worker about their situation.
