An Illinois Affidavit of Heirship-Surviving Spouse or Descendant is a legal document that is used to document the legal right of a surviving spouse or descendant to inherit property from a deceased person's estate. This document is typically used when an individual dies without a will, or when the will does not explicitly name the surviving spouse or descendant as the inheritor of the estate. The affidavit serves as evidence of the legal relationship between the surviving spouse or descendant and the deceased person. The affidavit must be completed by a qualified attorney and must include the name and address of the deceased person, the name of the surviving spouse or descendant, the relationship of the surviving spouse or descendant to the deceased person, and the description of the property that is being inherited. The affidavit should also be signed by the surviving spouse or descendant and notarized. There are a few different types of Illinois Affidavit of Heirship-Surviving Spouse or Descendant. These include an Affidavit of Heirship-Surviving Spouse or Descendant for an Inheritance Tax Waiver, an Affidavit of Heirship-Surviving Spouse or Descendant for an Estate Tax Waiver, and an Affidavit of Heirship-Surviving Spouse or Descendant for a Homestead Exemption Waiver. Each type of affidavit is used for a different purpose and requires different information to be included.
