Usually age 18 and in some states age 21, 23. Check your state law as to when a minor becomes an adult.
In this case it does not really matter who have custody since a minor is not allowed to choose and you have to be 18 to do so and by then you are free to live with whoever you choose.
The guidelines are basically the same in every state but obviously there are a few minor differences. Joint custody consists of Primary Custody & Secondary Custody. The parent with primary custody is who the child lives with & the other parent has secondary custody. Depending on the age of the child & the state in which they reside, the court may let them determine where they choose to live. Or if both parents agree on the child's decision then the child can live with either parent.
A minor can not choose where to live. That is up to the parents or the court depending on the details. If your non-custodial parent who lives out of state wants you to live with him/her, they have to petition for custody unless your custodial parent will consent to the change and join in a modification of the custody order.
A 12yo child is not allowed to choose where to live so if the parents have decided on this they have to go to court to change the custody order.
In Texas, if a child is 14 or older, he/she can choose to live with a grandparent as long as permission is given by the custodial parent.
No, legally a minor has no choice in the matter.
I believe that the minimum age is 12.
If you have joint custody, there is one parent that is the custodial parent. A child can move in with you if you are the custodial parent or you can file in court to change your status to the custodial parent. The child should want to live with you as well.
Length of time a child lives with a parent is not a factor in determining custody or modifying it. Custody is awarded based on the court's opinion of the child's best interests.
For the grandparents to get the custody over the parent, they have to go through a court case and prove to their case to have custody.
Yes. A child as young as 11 years old can choose which parent they wish to live with. It doesn't mean however that a judge will grant it, it merely means that the child can file formally with the court for a change in custody.
Generally no. A change in custody must be made by a court order.
First, the child has no specific right to choose which parent to live with without a court order. As to this issue, the other parent could file an emergency motion for custody on the grounds of abandonment.
