At 18 you are an adult and do not need parents permission for ANYTHING.
about all of them I would think
you have to be 18 to legally move out of your parents house without there permission and they technically can't make you stay because you aren't a minor and they have no control over you.
Yes, taking your parent's car without permission and running away with it would be considered theft. It is illegal to take someone else's property without their consent, even if they are your parents.
Unless she has the parents' permission or the court's (she would have to prove the parents unfit), she doesn't...unless she wants to go to jail.
It is legal if the 17 year-old's parents give permission to get married. Without their permission it would not be valid.
Unless the 14 year old has been emancipated, which is every unlikely, the 14 year old is required to do whatever the parents want them to do. If the parents give permission for her to move, then she may do so. However, without her parents' permission, she would be considered a "Runaway", and the police may escort her home and potentially charge her with status offenses.
A parent may take their child without permission due to a variety of reasons, such as a custody dispute, concerns for the child's safety or well-being, or a breakdown in communication between the parents.
Not without your parents' permission.
You ask for their permission because without it you can not move out. Would be clever to have a proper plan to show them.
Generally yes. However, you cannot engage in any illegal activity, with or without the parents permission, including physical contact that would be prohibited by law. Additionally, be aware, that depending on the age difference, you may still be in violation of the law, even with the parents permission. (For example, if you were a thirty year old man with a ten year old girl...this is child endangerment, and you and the parents could be prosecuted).
In Indiana, the legal age of majority is 18. Therefore, a 17-year-old would typically require permission from a parent or legal guardian to move out. If the minor decides to leave without permission, the parents could involve law enforcement to enforce their parental rights.
No, you are considered a minor until you are 18 years old. Your parents are responsible for you until you are 18. If you just leave home without permission from them you would be considered a runaway.
