Illinois Mailed Notice To Creditors is a notice sent by the estate of a deceased individual, or a fiduciary in charge of the estate, to creditors of the deceased or the estate. The notice informs creditors of the date of death or the date of the estate filing, and provides the creditor with information regarding how to make a claim against the estate. This notice is typically sent via certified mail to all known creditors of the decedent or the estate. There are two types of Illinois Mailed Notice To Creditors: 1. Reprobate Notice — This type of notice is sent to all known creditors prior to the estate being probated. It informs creditors of the decedent's passing and provides details on how to file a claim against the estate. 2. Post-Probate Notice — This type of notice is sent to all known creditors after the estate has been probated. It provides details on how to file a claim against the estate, and serves as a reminder to creditors that the estate is now in probate.
