Royalty money that could not be paid does not vanish. It sits with the operator, then goes to the state, under the name of whoever owned the minerals, which is often someone who died years ago. Here is where Illinois puts it, how long it takes to get there, and how to get it back. The search is free and so is our help.
Updated November 2026. Written by Stephen Clayman, career landman and owner of Berlin Royalties. Statutes were checked against primary sources; where we could not confirm a detail the page says so. This is general information from a buyer, not legal advice.
Search the Illinois State Treasurer, ICash database under the name of every family member who ever owned the minerals, including maiden names, initials and misspellings. Then call the operator's owner relations department, because money inside the dormancy period is still at the operator and will not show up in the state's search. Both steps are free, and we will run both for you free.
The Illinois search is run by the Illinois State Treasurer, ICash at icash.illinoistreasurer.gov/. Search by name only, so try every variant. For money still at the operator, our free operator directory has the owner relations contact for every company registered in the state, including the ones that no longer exist, which is where older wells' money usually sits.
Three years under 765 ILCS 1026/15-201(15), the earlier of three years after the owner first has a right to demand the money or the obligation to pay arises. A deceased owner's property is presumed abandoned two years from the last indication of interest. Illinois' act defines mineral proceeds to include royalties, bonuses, delay rentals, and overriding and net revenue interests.
The Illinois definition of mineral proceeds follows the uniform act, which includes later-accruing payments after the first abandonment, but we could not open the definition section to confirm the exact text. Ask ICash when you claim. In a pay-to-current state, once an owner's first payment is reported, every later royalty follows it, so the state's balance under a family name keeps growing and the operator holds nothing. In the other states, each payment runs its own clock, and the newest money is still with the operator.
ICash accepts a small estate affidavit listing all heirs and their percentages, where it is valid in the state of death, or letters of office from a probate, plus power of attorney or guardianship papers if you act for an heir. Documents can be uploaded or emailed. There is no fee. The state pays the owner of record or that owner's legal successor, so the title question and the claim question are the same question: who inherited the minerals, and what document proves it. Our page on inherited mineral rights in Illinois covers which document the state requires and how to get it.
We could not confirm Illinois' finder-fee cap from the statute. The search and the claim are free. Companies that write to heirs offering to "recover" unclaimed royalties for a percentage are selling you a search you can run in two minutes. Some of them also ask for the minerals themselves. Do not sign anything that conveys an interest in exchange for help with a claim.
Send a photo of whatever you have. We will identify the interest, tell you why the money is suspended, and tell you what document unlocks it. Free, and the answer is the same whether or not you sell.

Yes, at the New York Federal Reserve discount rate under the Oil and Gas Rights Act, 765 ILCS 520/10, after 30 days written notice. That applies to money the operator still holds.
