What Is an Affidavit of Heirship?

An affidavit of heirship is a sworn statement, typically signed by a disinterested third party with knowledge of the deceased's family, that identifies the heirs of a deceased person. In real-property contexts, recorded affidavits of heirship serve as evidence of ownership transfer when formal probate has not been completed.

For inherited Illinois mineral rights, an affidavit of heirship can sometimes be used in lieu of probate to update the public record and notify the operator, particularly for smaller estates or when probate is impractical. Whether an affidavit is acceptable depends on the operator's title standards and the title insurance underwriter's requirements.

When an Affidavit Works

Small estate where the only or primary asset is the mineral interest

The deceased died intestate (without a will) and heirs are clearly identifiable

No competing claims or contested heirship

Operator and any title insurance underwriter accept the affidavit as evidence of title

An affidavit of heirship is not a substitute for full probate when probate is required by Illinois law or by the title underwriter. Many oil and gas closings in Illinois require formal probate, particularly for larger interests.

Filing the Affidavit

An Illinois affidavit of heirship is typically:

Drafted by an Illinois attorney

Signed by a disinterested affiant familiar with the deceased's family history

Notarized

Recorded at the Illinois county recorder where the mineral interest is located

Submitted to the operator with a request for division order updates
