The ICPC is a law adopted by all 50 states which requires that the state the child is leaving (sending state) to notify the state the child is going to (receiving state) that the child is coming to live in the receiving state. All states have rules on what must be in the package of information submitted to their ICPC office, and the rules differ from state to state. Children moving across state lines must have the approval of both states before they can legally come to the receiving state.
In most interstate state adoptions, adoptive families can expect a delay of up to 2 weeks in bringing a child home after birth while the ICPC process goes on.
Penalties for failure to give proper ICPC notice and receive approval for moving the child range from criminal penalties in some states to the state having the right to object to an adoption being allowed. Because of the potential risk to an adoption, it is always best to consult with an attorney experienced in this area of adoption law.
