Quick answer

Unclaimed oil and gas royalties in Kansas are held by the Kansas State Treasurer — Unclaimed Property; search its official site, missingmoney.ks.gov, under every name the royalties may have been paid to. Kansas presumes unpaid property abandoned after 5 years (K.S.A. 58-3935(a)(16) ('all other property'); 'mineral proceeds' defined in K.S.A. 58-3934), and the holder must then report it to the state.

## How to claim and what proof you need

Kansas claimants search and file online and must document ownership, usually by proving they lived at the reported address or did business with the reporting company at the time. Documents are uploaded through a secure portal or mailed, never faxed or emailed.

**How to file:** Search by name on the Treasurer's site and file online; upload documents through the secure portal or mail them (no fax or email). Documents needing a notary or an original death certificate must be mailed.

**Proof required:** Documentation verifying ownership: proof of residence at the reported address or of business dealings with the reporting company in the relevant period (e.g., utility bills, bank statements, tax records, an old driver's license); proof of any name change.

## Claiming for a deceased owner

Heirs must document their legal right or relationship to the deceased owner, for example with an obituary listing surviving heirs or letters testamentary or of administration. Without a valid will or trust, the Treasurer applies Kansas intestate succession and pays each heir directly.

**Documents:** Documentation of legal right or relationship to the deceased, such as an obituary listing surviving heirs or court documents (Letters Testamentary or Letters of Administration) naming the personal representative; without a valid will or trust, Kansas intestate succession decides who may claim; an Affidavit of Heirship may need notarization.

Whether an estate must be opened is a legal question for a qualified attorney in that state.

## Fees and finder services

The Treasurer never charges to search or claim. Agreements to pay a finder are unenforceable if made within 24 months after the property reaches the state, and later ones are unenforceable if the fee exceeds 15% of the property's value.

**State claim fee:** None

**Finder-fee limit:** 15% of the value of the recoverable property for agreements made more than 24 months after the property is delivered to the state; agreements made within those 24 months are unenforceable

**Finder-fee statute:** K.S.A. 58-3968
