There is no standard answer to this question. If you wish to modify a custody order to become the primary residential parent and the other parent agrees, then a judge may sign off on the change and issue a new order. If not, you will need to show the court why it is in your child’s best interests to live with you more than with the other parent. Depending on the situation and your child’s age and maturity, the judge may or may not take their wishes into account.
