What are the record retention rules for lock boxes in Illinois, including customer’s statements, logs, and any other type of information related to the lock box? Also, what are the record retention requirements for email, either between bank staff and customers, or internally among bank staff related to a transaction?

Disclaimer: The Electronic Commerce Security Act (ECSA) was repealed and replaced with the Uniform Electronic Transaction Act (UETA), effective June 25, 2021. Please note that this change may affect the continued accuracy of this guidance as it pertains to the ECSA.

We are not aware of any specific legal requirements in Illinois that apply to the retention of lock box statements, logs, or other related documentation. Although the Illinois Banking Act mandates the Commissioner of Banks to promulgate record retention rules, no such rules have been published.

However, the statute of limitations for written contracts in Illinois is ten years. Consequently, we recommend retaining any lock box contracts for ten years after the termination of the contracts. This retention period should also be applied to any document, including email correspondence, that may be relevant to a dispute over a lock box contract.

For other lock box records, the IBA’s Record Retention Manual, last revised in 2014, suggests a retention period of five years. The FinCEN’s Bank Secrecy Act rules also require banks to retain any identifying information required by their Customer Identification Program (CIP) regulations for five years after a lock box account is closed or becomes dormant.

The retention period for transaction-specific email correspondence depends on the content of the message and the parties involved. Under the SEC rules, broker-dealers must retain electronic communications with customers and those that relate to their business for a least three years. In addition, the FinCEN’s Bank Secrecy Act rules require a five-year retention period for copies of requests or instructions (which may be received via email) regarding certain transfers of funds in excess of $10,000 when sent to or from parties outside the United States.

As previously mentioned, due to Illinois’ ten-year statute of limitations on written contracts, we recommend retaining any email correspondence that may be relevant to a dispute over a contract for ten years after the contract’s termination. For other email correspondence, the IBA’s Record Retention Manual generally recommends retaining email correspondence related to a customer deposit or loan account for five years and destroying non-sensitive or inconsequential emails at the bank’s discretion.

Finally, we note that both Illinois and federal law provide that an electronic copy of a document cannot be denied legal effect, validity, or enforceability solely because it is in electronic form (except for certain documents, such as wills and trusts). All of the documents mentioned in our answer may be retained electronically; you are not required to maintain paper copies of such records.
