An Illinois Affidavit of Warship is a legal document that is used to establish the inheritance rights of the heirs of a deceased person. It is typically used when the deceased passed away without leaving a will. The affidavit is completed by two or more credible witnesses who have personal knowledge of the family and/or the deceased's assets and can provide evidence to support the heirs' claims. The affidavit must be submitted to the probate court in order to obtain a court order for the transfer of the deceased's assets to the heirs. There are two types of Illinois Affidavit of Warship: Formal Affidavit of Warship and Informal Affidavit of Warship. Formal Affidavit of Warship must be sworn before a notary public, whereas Informal Affidavit of Warship is not sworn and must be witnessed by two or more credible witnesses. Both types of affidavits require evidence to support the claimed warship, such as birth certificates, marriage certificates, death certificates, or other legal documents.
