Who Must Maintain an COLTAF (Colorado's IOLTA program) Account?

Any attorney licensed in Colorado who receives client funds — whether retainers, settlement proceeds, real estate closing funds, or court awards awaiting disbursement — is generally required to deposit those funds into a designated COLTAF trust account. The account must be maintained at a qualified financial institution that has agreed to remit interest to Colorado Lawyer Trust Account Foundation. Client funds must remain completely separate from the firm's operating accounts at all times.

Small or short-term client funds that would not earn net interest for the client go into the COLTAF account, where the pooled interest is directed to legal aid and bar foundation programs. Larger or longer-term funds that would earn meaningful interest for a specific client should be placed in a separate interest-bearing account for that client's benefit — not in the pooled COLTAF account.

Reconciliation Requirements

Colorado requires monthly three-way reconciliation of your COLTAFtrust account. Three-way reconciliation means verifying that three figures agree: your adjusted bank statement balance, your check register (book) balance, and the sum of all individual client sub-ledger balances. All three must match — it is not sufficient for the bank balance and book balance to agree if the per-client ledgers don't add up to the same total.

Colorado requires reconciliations to be prepared in writing and signed. A verbal or informal reconciliation does not satisfy the rule. The signed reconciliation report must be retained in your files along with the supporting bank statements.

If a discrepancy is found, it must be identified and corrected. Completing the reconciliation and leaving a known discrepancy unresolved is itself a violation. Common causes of discrepancies include transposed amounts, disbursements posted to the wrong client matter, uncleared checks not properly tracked, and bank fees that were not recorded.

Record Retention

Colorado requires attorneys to retain trust account records for a minimum of 5 years. Records that must be kept include bank statements, canceled checks or check images, deposit slips, reconciliation reports, and the client ledger showing each transaction for every client matter.

Many attorneys retain records longer than the 5-year minimum as a matter of professional caution — bar complaints and civil malpractice claims can sometimes surface years after a matter closes. Electronic records are generally acceptable provided they are complete and accessible.

Overdraft Notification

Colorado requires participating financial institutions to notify the state bar if any check or other instrument drawn on a COLTAF account is presented against insufficient funds — regardless of whether the bank honors or returns the item. This means even a momentary overdraft that is immediately corrected will trigger a bar notification and likely a follow-up inquiry. Maintaining accurate real-time records and never disbursing more than the available balance is essential.

Audit Requirements

Colorado does not currently operate a routine random audit program. Trust account examinations are typically triggered by a client complaint, a bank overdraft notification, a disciplinary referral, or a targeted compliance review. However, the absence of a random program does not reduce your obligation to maintain complete and accurate records — bar examinations can still occur and records must be available.

When a Colorado bar examiner reviews a trust account, they will typically request monthly reconciliation reports for the past 12–36 months, bank statements for the same period, a complete transaction ledger, and individual client sub-ledgers. The examiner may select specific client matters at random and trace every transaction from opening to close. If your sub-ledgers reconcile to the bank balance and your reconciliations are current and signed, the examination is typically straightforward.

Unclaimed Funds and Escheatment

Client funds held in your COLTAF trust account that remain unclaimed for 5 years may be subject to Colorado's unclaimed property (escheatment) laws. When a client matter closes with a remaining balance and you cannot locate the client after documented good-faith attempts, the remaining funds must typically be remitted to the state. The specific procedures — including required notice to the client, the waiting period, and the remittance process — are governed by Colorado's unclaimed property statutes. Failing to remit escheated funds can itself be a separate legal and ethical violation.
