Well, depends. Does Mom have custody? Is child under-aged?
yes
No, they cannot do so. The need permission or a court order.
She would ask her parents or legal guardians.
Normally in the United States. an eleven year old can move in with grandparents with parental permission. This should be in writing. Many stationary stores have appropriate legal forms or a lawyer may assist in the process. Usually a legal form is not needed for overnight or a few days, but if the 11 year old will be going to school or on activities for which the grandparents must sign a piece of paper, it should be done.
Yes, you can legally move in without their permission. They had to give permission for you to get married and that emancipates you.
Not in the United States unless you get emancipated
no
Without their permission they will have to wait until they are 18. The parents are still responsible for them.
No, that is no longer an option unless the grandparents (now parents) give permission. In order for the grandparents to adopt, the father's rights had to have been given up.
A minor will need parental permission before moving.
A 17-year-old is not a woman, she is a minor, and therefore, no, she cannot move out without her parents permission unless she has been legally emancipated.
No she can not.
