An Illinois Approval Order is a type of court order issued by the Illinois Supreme Court in response to a petition for approval of a transaction that involves the sale, transfer, or exchange of a legal interest in real estate. The Order grants approval for the transaction, and serves as proof that the transaction is valid and binding. There are two types of Illinois Approval Order: an Order of Approval for a Voluntary Transaction and an Order of Approval for a Non-Voluntary Transaction. The Order of Approval for a Voluntary Transaction is applicable for transactions that are entered into voluntarily by the parties involved, while the Order of Approval for a Non-Voluntary Transaction is applicable for transactions that are imposed by law or court order.
