In Missouri the change in the principal residence of a child (i.e. relocation) without the notice required in Section 452.377 R.S. Mo can be deemed a change in circumstances allowing the court to modify a prior custody decree. In relocation cases, there are strict time standards which must be complied with. If you are contemplating moving or the other party has notified you of an intention to move, please contact us immediately to arrange a time to meet to discuss your case.
