The custodial parent
can relocate with the children, unless the current custody orders prohibit relocation without prior notice. Because Iowa law permits a court to find a change in circumstances sufficient to modify custody, whenever a custodial parent relocates a child beyond 150 miles from the child's former residence, it is typical to for custody orders to require notice before a relocation.
Assuming that your orders are as described, then the relocation in advance of the 60-day notice, would be contempt of court, and the judge could order the children returned to Iowa.
Whether or not the judge would actually do this, depends greatly on the judge's predisposition in such matters. Frankly, many judges don't like to get involved in this sort of battle, because it always ends badly, and once the children are already socialized to a new environment, the judge will be even less likely to order the children's return.
Consequently, by getting a restraining order
, before relocation occurs, you are in a much better legal position, because then the judge will be angry that the custodial parent has violated the express restraining order.
