755 ILCS 65/50: Disputes.

(a) Any dispute among any of the persons listed in Section 5 concerning their right to control the disposition, including cremation, of a decedent's remains shall be resolved by a court of competent jurisdiction within 30 days of the dispute being filed with the court. A cemetery organization or funeral establishment shall not be liable for refusing to accept the decedent's remains, or to inter or otherwise dispose of the decedent's remains, until it receives a court order or other suitable confirmation that the dispute has been resolved or settled.

(b) Any dispute over a disinterment shall be resolved by a circuit court with all reasonable promptness by the court. If the court finds that a party to a disinterment dispute has acted in bad faith, the court may, in its sole discretion, award costs, including reasonable attorney's fees, against the person it finds has acted in bad faith.
