Colorado IOLTA
Program: Colorado Lawyer Trust Account Foundation (COLTAF)
Colorado lawyers in private practice must place nominal or short-term entrusted funds in a pooled COLTAF trust account, while funds capable of earning net interest for their owner belong in a client-benefit account. Colorado adds approved-institution, account-labeling, overdraft-reporting, quarterly reconciliation, annual reporting, and seven-year recordkeeping controls.

Colorado — Frequently asked
Common questions for Colorado trust accounts. General information only — verify against the official sources above.
What is a Colorado COLTAF account?
It is a pooled lawyer trust account for client or third-party funds that are nominal in amount or expected to be held so briefly that they cannot earn net interest for their owner after reasonable account costs.
Who administers Colorado's IOLTA program?
The Colorado Lawyer Trust Account Foundation, commonly called COLTAF, receives interest from COLTAF trust accounts and supports Colorado's civil legal-aid system.
When must a Colorado lawyer maintain a trust account?
A lawyer in private practice must maintain a separate trust account whenever the lawyer or firm holds entrusted funds, unearned advance fees, or advance expenses not yet incurred. No account is required if the lawyer holds none of those funds.
Which funds belong in a COLTAF account?
Use COLTAF for funds that are nominal or expected to be held briefly when client-specific interest would not exceed the reasonable costs of a separate interest-bearing account.
When should funds earn interest for the client instead?
If the amount and expected duration can generate net interest after account and administrative costs, the lawyer should use an interest-bearing account that benefits the client or third person.
Who decides whether funds are nominal or short term?
The lawyer makes a good-faith professional judgment using the amount, expected duration, interest rate, account costs, transaction circumstances, and likelihood of delay, and should reassess if circumstances change.
Who owns interest earned on a COLTAF account?
COLTAF receives it directly. The lawyer and law firm have no right or claim to COLTAF-account interest or dividends.
May a COLTAF account be held at any bank?
No. It must be at a financial institution approved by Colorado Attorney Regulation Counsel under Rule 1.15E.
Must a COLTAF account be insured and interest bearing?
Yes. Rule 1.15B requires a COLTAF account to be an interest-bearing or dividend-paying insured depository account.
How must a Colorado IOLTA account be titled?
The account, checks, and deposit slips must be prominently labeled 'COLTAF Trust Account.' Additional wording is allowed only if it is not misleading.
What happens if a COLTAF check is presented against insufficient funds?
The approved institution must notify Attorney Regulation Counsel when a properly payable trust-account instrument is presented against insufficient funds, whether or not the bank honors it.
What trust-account information is reported annually?
With annual attorney registration, the lawyer reports each trust account's identifying information, account name, and depository institution as required by the registration rules.
Where do unearned advance fees go in Colorado?
Advance fees that have not been earned and advance expenses that have not been incurred must be deposited in the trust account until the lawyer is entitled to withdraw them.
Can Colorado trust-account funds be withdrawn in cash or by debit card?
No. Rule 1.15C prohibits cash withdrawals and withdrawals using a debit card or ATM card.
What does depositing funds intact mean?
The complete payment is first deposited into trust even if part may later become an earned fee. After the funds are collected and interests are determined, proper amounts can be disbursed.
How often must Colorado trust accounts be reconciled?
Every trust account must be reconciled at least quarterly by a Colorado-admitted lawyer or by someone working under that lawyer's supervision.
What core ledgers must a Colorado lawyer keep?
Maintain a general trust-account ledger and separate ledgers for every client or third person whose funds are held, with enough detail to trace each receipt, charge, withdrawal, and disbursement.
Which supporting documents must be retained?
Rule 1.15D records include bank statements and cancelled checks, deposit and disbursement records, fee and compensation agreements, client statements and bills, and records of certain payments for services.
How long must Colorado trust-account records be kept?
The financial records required by Rule 1.15D generally must be kept for seven years under the rule's timing provisions.
Can trust-account bookkeeping be delegated to staff?
Yes, but only under proper supervision. The lawyer remains responsible, should separate incompatible duties, and must ensure the required quarterly reconciliation is performed by a Colorado lawyer or someone under that lawyer's supervision.
