When a probate estate is opened the petitioner is obligated to establish the heirs of the decedent. This is usually done by affidavit that sets out the marital status of the decedent and the decedents children, born or adopted. If no children the parents and siblings and any relations though the parents and siblings. The petitioner is required to give notice of the hearing on the petition to open the estate or of the order entered at the hearing, depending on the nature of the estate and notice requirements or waivers of notice. An interested person can file an objection to the heirship, either as proposed or as entered by the Court. The objection must be timely. If the fiance cannot prove there was a marriage she will would not be an heir, though she could be a legatee under a will. Common law marriages are not recognized in Illinois though she may be able to prove a common law marriage recognized in another state where the couple resided that would have to be recognized in Illinois.
