No they can not. If they take the child across state lines it is kidnapping.
No, you cannot move a child out of state if you have joint custody.
Can a father who has joint custody with the mother stop her from visiting another state with the child
Only with permission from the other parent and the court.
With an injunction
First, a injunction should be filed to stop the move, or have the parent ordered to return the child to the jurisdiction of the court. Further, a motion for contempt for interference in custody, and a motion to modify the custody order due to this violation.
no you can move out of state if you have joint custody.
can a prent who shares joint custody move to a different city but is staying within the same state?
File an injunction ordering the child be returned. But, be prepared for a false allegation, which is common in these cases.
If you have joint custody, you cannot move out of the state with the child without the other parent's consent. Even if you have sole legal custody you cannot interfere with the other parent's visitation rights by moving. The visitation order must be modified. Absent the consent of the other parent, you need the permission of the court.
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.
