Illinois Proof of Delivery (SCA) is a document used to prove that goods purchased in the state of Illinois have been received by the buyer. It is often used in situations where goods are shipped or delivered from one party to another. The document is a signed and notarized document that provides evidence that the goods were in fact received by the purchaser. It is often used in cases of dispute resolution related to a sale transaction. The two main types of Illinois Proof of Delivery (SCA) documents are the Standard Proof of Delivery (SCA) and the Enhanced Proof of Delivery (SCA). The Standard Proof of Delivery (SCA) includes the signature of the recipient of the goods, along with the date and time of receipt. The Enhanced Proof of Delivery (SCA) includes additional features such as a photograph of the recipient, a description of the goods received, and a copy of the invoice. Both types of documents must be signed and notarized to be legally binding.
