4.1 Montana Trust Account Requirements

Key Takeaways

  • Broker trust accounts must be held in an insured Montana financial institution and identified as a 'trust account' (ARM 24.210.426)
  • Only a broker (or property manager) maintains a trust account; a salesperson never holds client funds in their own name
  • Trust funds must be retained until the transaction closes or terminates, and disbursed only per contract or written agreement of the parties
  • Commingling (mixing client and personal funds) and conversion (using client funds for unauthorized purposes) are prohibited and disciplinable
  • Brokers must keep complete records — bank statements, deposit/disbursement records, client ledgers, and reconciliations — for the required retention period, subject to Board audit

Trust-account rules protect client money and are among the most heavily tested Montana topics. The governing rule is ARM 24.210.426, and the core idea is segregation: other people's money is held separately and accounted for at all times.

What Is a Trust Account?

A trust account (or escrow account) is a dedicated bank account where a broker holds funds belonging to others:

Fund typeExample
Earnest moneyA buyer's good-faith deposit
Security depositsTenant deposits on managed rentals
Rent collectionsRent held for owners
Other client fundsProceeds pending disbursement

Only a broker (or a property manager for managed funds) maintains the account. A salesperson never holds client funds in their own name — funds received are promptly delivered to the supervising broker.

Account Requirements (ARM 24.210.426)

RequirementDetail
LocationAn insured financial institution located in Montana
NameThe account name must include "trust account"
SegregationClient funds kept separate from the broker's operating funds
AccountabilityThe broker must account for the funds at all times
AvailabilityRecords must be readily available for Board audit

Key rule: The account must be clearly identified as a trust account at an insured Montana institution. A general business account, or an out-of-state account, does not satisfy the rule.

A broker may keep a small amount of the broker's own money in the trust account solely to cover bank service charges or maintain a minimum balance — that narrow exception is not commingling. Anything beyond that minimal cushion is prohibited.

Deposit, Retention, and Disbursement

Holding the funds

RequirementDetail
Deposit timingPromptly, per the contract and Board rules
RetentionHold until the transaction closes or terminates
DisbursementOnly per the contract terms or the written agreement of the parties

Disputed funds

If the buyer and seller dispute who is entitled to the earnest money, the broker must not simply pick a side. The broker holds the funds until the parties agree in writing, a court orders disbursement, or the broker uses an authorized process (such as interpleader) to deposit the disputed funds with the court.

Dishonored-deposit protection

A broker is not disciplined for a negative balance that results solely from a deposit that was dishonored after the institution indicated the funds were available — i.e., a bounced check the broker reasonably relied on.

Prohibited Practices: Commingling and Conversion

Commingling

Commingling is mixing client funds with the broker's personal or business funds. It is prohibited — even if no client loses money.

AllowedNOT allowed
Client funds in the trust accountClient funds in the operating account
A small cushion for bank feesLarge broker funds parked in the trust account
Disbursing per agreementUsing client funds for business expenses

Conversion

Conversion is using client funds for an unauthorized purpose — a far more serious violation that can lead to license revocation, criminal charges, and civil liability. Conversion is intentional misappropriation, not merely sloppy bookkeeping.

Exam point: Distinguish the two. Commingling = mixing funds (a violation by itself). Conversion = spending/using client funds without authorization (theft-level).

Recordkeeping and Board Audits

Brokers must maintain complete trust-account records:

RecordPurpose
Bank statementsMonthly institution statements
Deposit recordsProof of each deposit
Disbursement recordsProof of each payment
Client ledgersPer-transaction running balances
ReconciliationsPeriodic (monthly) account reconciliation

Records must be retained for the period the Board requires and produced on demand. The Board may audit trust accounts at any time and during any investigation.

Common audit findings

IssueLikely consequence
Shortage of fundsSerious — potential revocation
ComminglingFine to revocation
Poor records / no reconciliationWarning to suspension
Late depositsWarning to fine
Missing "trust account" designationAdministrative violation

Putting it together: The broker is personally responsible for the trust account, even for funds a salesperson mishandles before delivery. Sound recordkeeping and monthly reconciliation are the broker's best defense in an audit.

Reconciliation: The Three-Way Tie-Out

The gold standard the Board expects is a three-way reconciliation, performed regularly (monthly). It confirms that three numbers agree:

SourceShould equal
Bank balance (reconciled to the statement)=
Trust ledger / checkbook balance=
Sum of all client sub-ledgers(the total of every individual transaction balance)

If the three do not tie out, there is a shortage or overage that must be investigated immediately. A shortage (less in the account than clients are owed) is the most serious finding — it suggests funds were used improperly. An overage (more than owed) often signals commingled broker money that should be removed (beyond the small service-fee cushion).

A Worked Trust Scenario

A broker holds $5,000 earnest money for the Smith deal and $3,000 for the Jones deal — the trust account should show $8,000 attributable to those two client ledgers. If the bank shows $7,500, there is a $500 shortage: a red-flag the Board treats as potential conversion until explained. If it shows $8,400 and the extra $400 is the broker's own money beyond a bank-fee cushion, that is commingling.

Exam tip: When a trust question gives you ledger figures, add the client sub-ledgers and compare to the bank balance. A mismatch is the violation — short = likely conversion; extra broker funds = commingling.
