Missouri IOLTA Note
Missouri Rule 4-1.15 governs IOLTA trust accounting. Since July 2022, the rule requires that the responsible attorney personally review the monthly three-way reconciliation — delegation to staff is insufficient. Overdraft notifications go to the Office of Chief Disciplinary Counsel, and MLTAF (Missouri Lawyer Trust Account Foundation) administers the IOLTA program and collects quarterly interest remittances.

Missouri IOLTA Compliance FAQ
What rule governs IOLTA trust accounts in Missouri?
Missouri IOLTA trust accounts are governed by Missouri Rule 4-1.15. The rule sets the requirements for reconciliation frequency, record retention, client ledger maintenance, overdraft notification, and interest remittance to the Missouri IOLTA program.
How often must Missouri attorneys reconcile their IOLTA accounts?
Missouri attorneys have to complete a three-way reconciliation of their IOLTA trust accounts monthly. Three-way reconciliation lines up the bank statement balance, the trust account ledger balance, and the sum of every individual client ledger balance — and all three have to match.
How long must Missouri attorneys retain IOLTA records?
Missouri attorneys have to retain every IOLTA trust account record — bank statements, client ledgers, reconciliation reports, and disbursement documentation — for 5 years under Missouri Rule 4-1.15. Disbo keeps all of it automatically for the required period.
What happens if a Missouri IOLTA account is overdrawn?
Required — bank must notify Missouri Office of Chief Disciplinary Counsel. An overdraft notification can trigger a disciplinary review, and the only way to avoid that is to make sure cleared funds are actually in the trust account before any disbursement goes out. Disbo blocks transactions that would create a negative balance before they process.
Where does Missouri IOLTA interest go?
Quarterly to Missouri Lawyer Trust Account Foundation (MLTAF). The funds support civil legal aid programs for low-income residents throughout Missouri. Every IOLTA account has to be at an approved financial institution that forwards the interest to the Missouri IOLTA program.
Missouri IOLTA trust accounting is governed by Missouri Rule 4-1.15, which sets comprehensive requirements for every attorney in the state who holds client or third-party funds. Personal injury firms in Kansas City, St. Louis, Springfield, and throughout Missouri that manage settlement proceeds, medical lien payments, and attorney fee disbursements are subject to these requirements in full. The Missouri Lawyer Trust Account Foundation (MLTAF) administers the state's IOLTA program, collecting quarterly interest remittances from participating banks and distributing the proceeds to civil legal aid organizations across Missouri. Attorneys who want to stay compliant under Missouri Rule 4-1.15 need to understand not only the core requirements — monthly three-way reconciliation, five-year record retention, and overdraft notification to the Office of Chief Disciplinary Counsel — but also the July 2022 amendment that added a personal attorney review requirement to the monthly reconciliation process.
Missouri Lawyer Trust Account Foundation IOLTA Program
The Missouri Lawyer Trust Account Foundation (MLTAF) is the designated administrator of Missouri's IOLTA program. MLTAF's website at https://www.mltaf.org provides attorneys with information on the program's approved financial institutions, participation requirements, and compliance resources. Under Missouri Rule 4-1.15, attorneys who hold client funds that are nominal in amount or will be held for a short period must deposit those funds into an IOLTA account at an MLTAF-approved institution. Participating banks remit the interest earned on pooled IOLTA accounts to MLTAF on a quarterly basis, and MLTAF distributes those proceeds to Missouri legal aid organizations. The quarterly remittance cycle — unlike the annual or semi-annual cycles used in some other states — means that MLTAF and the participating banks have frequent opportunities to identify and address participation problems. Attorneys must verify that their bank remains on the MLTAF approved list when opening a new account or changing banking relationships.
Monthly Three-Way Reconciliation Under Missouri Rule 4-1.15
Missouri Rule 4-1.15 requires attorneys to complete a three-way reconciliation of their IOLTA trust accounts each month. The three-way reconciliation process verifies that the bank statement ending balance, the trust account ledger balance maintained by the firm, and the sum of all individual client matter ledger balances agree. All three figures must match. Discrepancies must be identified, investigated, and corrected in the same period — they cannot be carried forward. The reconciliation must be documented in writing and retained for at least five years. For Missouri PI firms with dozens of active matters, the per-matter ledger discipline required to make the reconciliation accurate is as important as the reconciliation itself: if any individual client ledger is out of balance, the three-way reconciliation will fail, and the discrepancy will trigger a review.
The July 2022 Personal Review Amendment
In July 2022, Missouri amended Rule 4-1.15 to add an explicit requirement that the responsible attorney personally review the monthly three-way reconciliation. This amendment was a significant change for Missouri firms that had delegated their trust accounting oversight to paralegals, bookkeepers, or law firm administrators. Under the amended rule, it is not sufficient for a staff member to prepare the reconciliation and sign off on it — the attorney must personally review the completed reconciliation and confirm that it is accurate. The practical implication is that the responsible attorney must be engaged in the trust accounting process at least once per month, reviewing the reconciliation worksheet, confirming that the three balances agree, and signing or otherwise documenting the review. Firms that rely on a delegation model without documented attorney review are non-compliant under the July 2022 amendment even if the underlying bookkeeping is accurate.
Overdraft Notification to the Office of Chief Disciplinary Counsel
When a Missouri IOLTA trust account is overdrawn, the bank is required by its MLTAF participation agreement to notify the Missouri Office of Chief Disciplinary Counsel. The Office of Chief Disciplinary Counsel is the body that investigates attorney misconduct and recommends discipline to the Missouri Supreme Court. An overdraft notification will typically prompt an inquiry into the attorney's trust account practices, and the circumstances of the overdraft — whether it was caused by a bank error, a timing issue, or an actual shortage — will determine the severity of the response. For Missouri PI firms, the cleared-funds discipline that prevents overdrafts is not just best practice — it is the only reliable way to avoid a disciplinary notification. Settlement checks should not be disbursed against until the bank confirms that the deposited funds have cleared.
Five-Year Record Retention
Missouri Rule 4-1.15 requires attorneys to retain all trust account records for a minimum of five years. The covered records include bank statements, deposit slips, cancelled checks or check images, wire transfer records, individual client matter ledgers, three-way reconciliation worksheets, the attorney's personal review documentation required since July 2022, and disbursement records. The five-year period runs from the date each record was created. Electronic storage is acceptable, provided records are maintained in a retrievable format and backed up. If the Office of Chief Disciplinary Counsel requests records in connection with an inquiry, the attorney must produce them promptly and in a format that allows the investigator to verify the three-way reconciliation for any given month.
Approved Financial Institutions in Missouri
Missouri IOLTA accounts must be held at financial institutions approved by MLTAF that have executed the required participation agreement. The participation agreement binds the bank to remit IOLTA interest to MLTAF quarterly and to notify the Office of Chief Disciplinary Counsel when a covered trust account is overdrawn. MLTAF maintains a current list of approved institutions on its website. When a firm opens a new trust account or changes banks, the attorney must confirm that the new institution is on the current approved list. An institution that was on the list in a prior year may have been removed if it failed to meet the program's remittance or notification requirements, so the list should be verified at the time of the account change rather than assumed based on prior approval.
Common Violations at Missouri Personal Injury Firms
Missouri PI firms face several recurring trust account compliance challenges. The most common is the disbursement of settlement proceeds before the deposited check has fully cleared, creating the risk of an overdraft that triggers an Office of Chief Disciplinary Counsel notification. The July 2022 personal review amendment has introduced a new category of violation: firms where the monthly reconciliation is prepared by staff but not reviewed and documented by the responsible attorney are non-compliant regardless of the accuracy of the underlying records. Missing per-matter client ledgers — particularly at high-volume PI firms that handle dozens of active matters — remain a frequent finding in disciplinary inquiries. Commingling occurs when earned fees are left in the trust account after they have been earned, or when unearned cost advances are deposited into the operating account rather than the trust account.
Automating Missouri IOLTA Compliance with Disbo
Disbo addresses the specific requirements of Missouri Rule 4-1.15, including the July 2022 personal review amendment. The platform maintains individual client matter ledgers for every active case, posts transactions in real time, and prevents any disbursement that would create a negative balance. Monthly three-way reconciliation is automated and presented as a formatted worksheet that the responsible attorney can review and sign off on in the platform — satisfying the personal review requirement directly in the workflow. Records are retained as immutable, date-stamped documents for the required five-year period. Missouri PI firms using Disbo replace manual spreadsheet tracking with a system that enforces Rule 4-1.15's requirements — including the 2022 personal review amendment — without requiring the attorney to build a compliance process from scratch.
Referral Fee Rules in Missouri — and How to Actually Pay Them
Trust account compliance and referral fee compliance go hand-in-hand for any Missouri firm that splits fees with co-counsel, accepts case referrals, or pays referring attorneys out of a settlement. The same Missouri Rule 4-1.15 that governs your IOLTA account also dictates how referral fees flow through it — and Missouri Rules of Professional Conduct Rule 4-1.5(e) adds a separate layer of disclosure, consent, and reasonableness rules on top.
Governing rule: Missouri Rules of Professional Conduct Rule 4-1.5(e)
The Missouri Referral Fee Standard, in Plain English
Missouri follows the ABA Model Rule 1.5(e) framework for fee divisions between lawyers who are not in the same firm. Referral fees and co-counsel splits are permitted only when the client gives informed written consent, the total fee is reasonable, and the division is either proportionate to services performed or each lawyer assumes joint responsibility for the matter.
- Client gives informed written consent to the fee division, including the share each lawyer will receive
- Division is in proportion to services performed by each lawyer, OR each lawyer assumes joint responsibility for the representation
- Total fee is reasonable
Once a Missouri matter resolves and the referral fee is owed, the trust accounting and the actual payment have to line up exactly. Disbo lets you pay attorney referral fees in Missouri directly from the settlement disbursement — with the client consent, fee split, and IOLTA ledger entries documented in one workflow.
The Referral Fee Workflow Most Missouri Firms Get Wrong
Almost every PI and employment firm in Missouri has the same broken referral fee workflow: the obligation lives in a spreadsheet, the disclosure lives in an email, the consent lives in a signed PDF in a shared drive, and the actual payment happens at the bank — completely outside the platform that holds the client funds. That gap is where bar discipline starts and where money gets lost. Here is what the end-to-end flow should look like under Missouri Rules of Professional Conduct Rule 4-1.5(e), and how Disbo executes it.
- 1
Intake — capture the referring attorney up front
When the matter is opened, the referring attorney's identity, firm, percentage share, and the basis for the division (proportionate services or joint responsibility, depending on what Missouri requires) are recorded as structured fields on the matter — not in a notes box.
- 2
Client disclosure and written consent
Disbo generates the Missouri-specific written disclosure and consent form pre-populated with the participating lawyers, the share each will receive, and the language Missouri Rules of Professional Conduct Rule 4-1.5(e) requires. The client signs it electronically and the executed form is bound to the matter file.
- 3
Settlement received into IOLTA
When settlement funds hit the IOLTA account, Disbo applies your three-way reconciliation rules under Missouri Rule 4-1.15 and posts the receipt to the client's individual ledger. Nothing is disbursed yet — including the referral fee.
- 4
Fee calculation and split preview
Disbo computes the attorney fee, the referring lawyer's share, the costs to be reimbursed, lien payoffs, and the client's net — all from the agreed percentages. The closing statement is generated automatically in the format your Missouri bar expects.
- 5
Compliance check before disbursement
Before any payment goes out, Disbo verifies the consent is on file, the client's trust balance is sufficient (no negative balance), the total fee is not unconscionable, and any state-specific caps or proportionality requirements are satisfied. If anything fails, the disbursement is blocked.
- 6
One-click payment to the referring attorney
Disbo pays the referring attorney directly out of the IOLTA disbursement by ACH, wire, or printed check — without leaving the platform, logging into your bank, or rekeying the amount. The payment is reconciled against the ledger in real time.
- 7
Audit-ready archive
The signed consent, the fee agreement, the closing statement, the ACH/wire receipt, and the ledger entry are stored together on the matter and retained for 5 years to satisfy Missouri's record retention rule.
Referral Fees by Practice Area in Missouri
Referral fees and co-counsel splits look different depending on the practice area. The underlying ethics rule under Missouri Rules of Professional Conduct Rule 4-1.5(e) is the same, but the money movement is not. Disbo handles all four of the patterns Missouri firms run into most.
Contingency referral fee from settlement
The classic PI flow. A referring attorney sends you a case, the matter settles, and a percentage of your contingency fee is owed to the referring lawyer. Disbo pays the referring attorney from the IOLTA disbursement, with the Missouri consent and closing statement already attached.
Hybrid contingency + invoiced business clients
Plaintiff-side employment cases are often contingency, but defense-side and advisory work for the same firm is hourly and billed to a business. Disbo lets you invoice businesses directly through the platform — generate the invoice, accept ACH or card payment, deposit operating funds (not IOLTA), and still record any referral or co-counsel split on the same matter.
Multi-firm fee splits with joint responsibility
When two or more {name} firms work a matter together — common in mass tort, complex litigation, and class actions — Disbo records each firm's percentage, the joint responsibility agreement required by Missouri Rules of Professional Conduct Rule 4-1.5(e), and disburses each firm's share separately at settlement.
Invoice a business for hourly fees
For defense work, in-house counsel arrangements, and business clients on retainer, Disbo lets you invoice the company directly, accept ACH/credit-card payment from the business, deposit it into the operating account (never IOLTA, per Missouri Rule 4-1.15), and route any agreed referral split to the referring attorney from operating — with the same documentation trail as a contingency split.
Invoice Business Clients Through the Same Platform — Even on Employment Disbursements
Most Missouri employment firms run a hybrid book of business: contingency wage-and-hour and discrimination cases on one side, and hourly defense, advisory, severance, and compliance work for businesses on the other. Disbo is built for both. You don't need a second tool to bill the corporate clients — and you don't need a third tool to pay a referring attorney when the case settles.
Issue invoices to businesses from the matter
Generate a branded invoice from any employment matter — defense work for an employer, advisory hours for HR counsel, severance negotiation, an ADA accommodation review. Line-item hourly entries, flat fees, or hybrid arrangements all flow into the same template.
Accept ACH and card payment directly
Businesses pay you online — ACH, credit card, or wire. Funds land in your operating account (not the IOLTA), the invoice is marked paid automatically, and the matter ledger shows the receipt next to the time entries it covered.
Recurring retainers and replenishment
Set up monthly retainers for business clients, automated replenishment when balances dip below a threshold, and credit-card-on-file for predictable corporate billing. The same platform that runs your IOLTA runs your A/R.
Pay the referring attorney from operating
When the business invoice is paid and a referral fee is owed, Disbo pays the referring attorney out of the operating account — not the IOLTA — and applies the same Missouri Rules of Professional Conduct Rule 4-1.5(e) consent and disclosure documentation you'd use on a contingency split.
One audit trail across IOLTA and operating
Whether the fee was contingent and disbursed from IOLTA, or hourly and invoiced to a business and paid from operating, the matter shows a unified audit trail: engagement letter, fee agreement, referral consent, time entries or settlement, invoice or closing statement, payment receipt, and the referral payment.

Common Missouri Referral Fee Mistakes
- Verbal-only fee splits with no signed client consent — unenforceable and a discipline risk under Missouri Rules of Professional Conduct Rule 4-1.5(e).
- Cutting the referring attorney's check from a personal account or operating account when the funds came from IOLTA, breaking the money trail.
- Disbursing the referral fee before the settlement check has actually cleared, creating a negative trust balance under Missouri Rule 4-1.15.
- Increasing the total fee charged to the client to absorb the referral split — a per se violation in most jurisdictions.
- Failing to document the basis for the division (proportionate services vs. joint responsibility) when the bar requires one.
- Mixing business-client invoices and IOLTA settlement receipts in the same account because the platform won't separate them.
What Disbo Enforces Automatically
- Blocks any referral fee disbursement when written client consent for that matter is not on file.
- Routes contingency-derived referral payments through IOLTA and business-invoice referral payments through operating — never the wrong direction.
- Refuses any disbursement that would create a negative client balance, no matter who the payee is.
- Locks the total client-charged fee so it can't be inflated to absorb a referral split.
- Prompts you to record proportionate-services or joint-responsibility basis when Missouri requires it.
- Generates the closing statement, payment receipt, and ledger entry as a single signed package retained for 5 years.
One platform, both sides of the ledger
Whether you're disbursing a contingent Missouri settlement out of IOLTA or invoicing a business client for hourly employment defense work, Disbo runs the trust accounting, the invoice, the payment rail, and the referral fee on a single matter — under the same Missouri Rules of Professional Conduct Rule 4-1.5(e) and Missouri Rule 4-1.15 rule set.
