I'm 18 years old.if I move out without my parents permission can my parents do anything about it?

No. If u r 18, u r free. Ur parents can't do anything about it legally

Legally no,you are an adult now.

There is nothing they can do about it but there is also nothing you can do to make them help you if you get in a jam. It always works better if you do things by agreement in case everything doesn't work out as planned.

legally I dont think so but before you do you might want to make shure you have a sustaining job and you can care for yourself like rent-wise and food-wise laundry,clothes, and other things

You are 18! Of course you can leave

I moved out when I was 17 with permission, so you should have a problem just don't forget them they have to cope with a change to a and they be there for you when you will need they hope this helps and sets you at ease
