An Illinois Affidavit of Warship No Surviving Spouse or Descendant is a legal document used to establish the warship of an individual in the state of Illinois when there is no surviving spouse or descendant. It is usually used to settle the estate of a deceased individual without the need for probate. There are two types of Illinois Affidavit of Warship No Surviving Spouse or Descendant: a Standard Form and a Simplified Form. The Standard Form is used when the decedent’s estate is complex and consists of multiple assets. The Simplified Form is used when the decedent’s estate is relatively simple and consists of only one asset. Both forms require the completion of a number of steps, including the completion of the Affidavit of Warship, the collection of information and documentation, and the submission of the forms to the probate court for approval.
