The Illinois Certificate of Depository-Receipt (CDR) is a form of legal document filed with the Illinois Secretary of State that records the transfer of ownership of property, such as securities, stocks, or bonds. It serves as a receipt for the transfer of the property, and is used to document the transfer of the ownership to a new owner. It is also used to transfer the title of the property to a third-party custodian or depository. There are two types of Illinois Certificate of Depository-Receipt: a Custodian CDR and a Non-Custodial CDR. A Custodian CDR is a document that is used to transfer title of securities to a third-party custodian or depository, while a Non-Custodial CDR is used to document the transfer of ownership between two parties without the involvement of a third-party custodian or depository. Both types of CDR's require the signature of the transferor and the transferee, as well as the date of the transfer, the amount of the transfer, and the type of security being transferred.
