A lawyer who practices in this jurisdiction shall maintain current financial records as provided in these Rules and required by Rule 1.15 of the South Carolina Rules of Professional Conduct, and shall retain the following records for a period of six years after termination of the representation:

 Rule 1 enumerates the basic financial records that a lawyer must maintain with regard to all client trust accounts of a law firm. These include the standard books of account and the supporting records that are necessary to safeguard and account for the receipt and disbursement of client or third person funds as required by Rule 1.15 of the South Carolina Rules of Professional Conduct. Consistent with Rule 1.15, this Rule proposes that lawyers maintain client trust account records for a period of six years after termination of each particular legal engagement or representation.
 Rule 1(g) requires that the physical or electronic equivalents of all checkbook registers, bank statements, records of deposit, pre-numbered canceled checks, and substitute checks be maintained for a period of six years after termination of each legal engagement or representation. The "Check Clearing for the 21st Century Act" or "Check 21 Act", codified at 12 U.S.C. §5001 et. seq., recognizes "substitute checks" as the legal equivalent of an original check. A "substitute check" is defined at 12 U.S.C. §5002(16) as a paper reproduction of the original check that contains an image of the front and back of the original check; bears a magnetic ink character recognition ("MICR") line containing all the information appearing on the MICR line of the original check; conforms with generally applicable industry standards for substitute checks; and is suitable for automated processing in the same manner as the original check. Banks, as defined in 12 U.S.C. §5002(2), are not required to return to customers the original canceled checks. Most banks now provide electronic images of checks to customers who have access to their accounts on internet-based websites. It is the lawyer's responsibility to download electronic images. Electronic images shall be maintained for the requisite number of years and shall be readily available for printing upon request or shall be printed and maintained for the requisite number of years.
 The ACH (Automated Clearing House) Network is an electronic funds transfer or payment system that primarily provides for the inter-bank clearing of electronic payments between originating and receiving participating financial institutions. ACH transactions are payment instructions to either debit or credit a deposit account. ACH payments are used in a variety of payment environments including bill payments, business-to-business payments, and government payments (e.g. tax refunds). In addition to the primary use of ACH transactions, retailers and third parties use the ACH system for other types of transactions including electronic check conversion (ECC). ECC is the process of transmitting MICR information from the bottom of a check, converting check payments to ACH transactions depending upon the authorization given by the account holder at the point-of-purchase. In this type of transaction, the lawyer should be careful to comply with the requirements of Rule 1(h).
 There are five types of check conversions where a lawyer should be careful to comply with the requirements of Rule 1(h). First, in a "point-of-purchase conversion," a paper check is converted into a debit at the point of purchase and the paper check is returned to the issuer. Second, in a "back-office conversion," a paper check is presented at the point of purchase and is later converted into a debit and the paper check is destroyed. Third, in an "account-receivable conversion,"a paper check is converted into a debit and the paper check is destroyed. Fourth, in a "telephone-initiated debit" or "check-by-phone" conversion, bank account information is provided via the telephone and the information is converted to a debit. Fifth, in a "web-initiated debit," an electronic payment is initiated through a secure web environment. Rule 1(h) applies to each type of electronic funds transfer described. All electronic funds transfers shall be recorded and a lawyer should not re-use a check number which has been previously used in an electronic transfer transaction.
 The potential for these records to serve as safeguards is realized only if the procedures set forth in Rule 1(i) are regularly performed. The trial balance is the sum of balances of each client's ledger card (or the electronic equivalent). Its value lies in comparing it on a monthly basis to a control balance. The control balance starts with the previous month's balance, then adds receipts from the Trust Receipts Journal and subtracts disbursements from the Trust Disbursements Journal. Once the total matches the trial balance, the reconciliation readily follows by adding amounts of any outstanding checks and subtracting any deposits not credited by the bank at month's end. This balance should agree with the bank statement. Monthly reconciliation is required by this rule.
 In some situations, documentation in addition to that listed in paragraphs (a) through (i) of Rule 1 is necessary for a complete understanding of a trust account transaction. The type of document that a lawyer must retain under paragraph (j) because it is "reasonably related" to a client trust transaction will vary depending on the nature of the transaction and the significance of the document in shedding light on the transaction. Examples of documents that typically must be retained under this paragraph include correspondence between the client and lawyer relating to a disagreement over fees or costs or the distribution of proceeds, settlement agreements contemplating payment of funds, settlement statements issued to the client, documentation relating to sharing litigation costs and attorney fees for subrogated claims, agreements for division of fees between lawyers, guarantees of payment to third parties out of proceeds recovered on behalf of a client, and copies of bills, receipts or correspondence related to any payments to third parties on behalf of a client (whether made from the client's funds or from the lawyer's funds advanced for the benefit of the client).
