Where a child lives is a long-term decision that should be made jointly with the child’s other parent (as a consequence of joint parental responsibility). Issues arise if you, or the other parent, unilaterally decide to relocate with your child or children.
Under family law, the court is unable to make an order that a parent not relocate to a new city, state or country. The reality is that you have a constitutional right to be autonomous and live wherever you want.
Family law courts can only make an order that your child or children remain where they are because relocation is not in the child or children’s best interests and would affect the time the child or children can spend with their other parent. Conversely, the court can grant relocation if it is in the child’s or children’s best interests to do so.
