As Chicago area business litigation lawyers this is a question we frequently are asked.
E-Signatures are permissible and valid in Illinois under the Illinois Electronic Commerce Security Act (the ECSA).
Under the ECSA e-signatures can be used for all contracts except for real estate title transfers where the document has to be recorded. The key point is to make sure that the contract has a provision that allows e-signatures.
