765 ILCS 835/9

When there is no memorial, monument, or marker installed on a cemetery interment right, entombment rights in a community mausoleum or lawn crypt section, or inurnment rights in a community columbarium; no interment in a cemetery interment right, entombment rights in a community mausoleum or lawn crypt section, or inurnment right in a community columbarium; no transfer or assignment of a cemetery interment right, entombment rights in a community mausoleum or lawn crypt section, or inurnment right in a community columbarium on the cemetery authority records; no contact by an owner recorded in the cemetery authority records; publication has been made in a newspaper of general circulation in the county in which the interment, entombment, or inurnment rights are located and no response was received; and 50 years have passed since the cemetery interment right, entombment rights in a community mausoleum or lawn crypt section, or inurnment right in a community columbarium was sold, there is a presumption that the cemetery interment right, entombment rights in a community mausoleum or lawn crypt section, or inurnment right in a community columbarium has been abandoned, unless a specific agreement has been entered into designating said rights to be inviolate. Alternatively, where there is an obligation to pay a cemetery authority, annually or periodically, maintenance or care charges on a cemetery interment right, entombment rights in a community mausoleum or lawn crypt section, or inurnment right in a community columbarium, or part thereof, and the owner of or claimant to a right or easement for burial in such cemetery interment right, entombment rights in a community mausoleum or lawn crypt section, or inurnment right in a community columbarium, or part thereof, has failed to pay the required annual or periodic maintenance or care charges for a period of 30 years or more, such continuous failure to do so creates and establishes a presumption that the cemetery interment right, entombment rights in a community mausoleum or lawn crypt section, or inurnment right in a community columbarium, or part thereof, has been abandoned. Upon a court's determination of abandonment, the ownership of a right or easement for burial in a cemetery interment right, entombment rights in a community mausoleum or lawn crypt section, or inurnment right in a community columbarium, or part thereof, shall be subject to sale in the manner hereinafter provided.
