Dormant Trust Balances:
Close Them Without Causing Compliance Headaches 

What happens when a trust account review reveals a balance that looks out of place? The matter has been closed, the work has been completed, and the file has likely moved out of sight for everyone involved. But the funds are still there.

For Canadian law firms, these dormant trust balances are common. At first, it may not seem urgent. The amount might be small and the explanation might be simple.

They often come from ordinary matter closeout issues, missed follow-up, or client communication challenges. But when they remain unresolved, they can create compliance risk that slowly builds in the background.

Managing dormant trust balances is part of good trust account hygiene. With a clearer process, your firm can investigate old balances, document reasonable efforts, and resolve inactive funds without creating unnecessary audit stress.

This is about keeping trust records clean, reducing compliance uncertainty, and giving your firm a more confident path to cleanup.

What Counts as a Dormant Trust Balance in Canada?

In Canada, a dormant trust balance is generally any client trust amount that remains in your account without meaningful activity for an extended period.

While definitions can vary slightly across Law Societies, funds that are no longer actively tied to ongoing legal work and have not been resolved within a reasonable timeframe begin to fall into the dormant category.

In practice, this often includes:

• Closed matters where a residual balance was never cleared
• Retainers that were only partially applied or refunded
• Unclaimed funds where the client is no longer reachable
• Older balances connected to disbursements or adjustments that were never finalised

Notice that dormancy does not just consider how long the funds have been sitting, but whether there is a clear path to resolution that is being actively pursued.

From a compliance perspective, inactive trust funds represent unfinished obligations to a client or third party. Even when the amounts are small, the expectation is that they will be investigated and addressed, not carried forward indefinitely.

Why Small Trust Balances Create Big Compliance Risk

If your firm is reviewing dormant trust balances, Canada compliance requirements should guide how you investigate, document, and resolve them.

A leftover balance might seem too minor to address right away. But in trust accounting, the size of the balance matters far less than how long it has been sitting unresolved.

An inactive balance, no matter how small, raises important questions around why the balance remains, what steps have been taken to resolve it, and whether or not documentation shows what happened and what was attempted.

During an audit or review, these questions contribute to a broader picture of how your firm manages trust funds overall.

One unresolved balance may not stand out, but several of them begin to signal a pattern. Patterns tend to draw closer scrutiny. There’s also a practical impact on your day-to-day operations.

Inactive trust balances in Canadian law firms can:

• Make reconciliations more time-consuming
• Create uncertainty in reporting
• Require additional review before confirming account accuracy
• Slow down routine trust accounting tasks

What starts as a small administrative detail can gradually introduce friction into your workflows and increase the effort required to maintain clean records.

When it comes to dormant trust balances, Canada law firms need a process that supports both cleanup and compliance.

5 Reasons Trust Balances Become Dormant

Dormant balances usually develop through routine workflows that never fully reach resolution. A matter moves forward and billing is finalised, but a small piece of the financial picture is left unfinished.

Several common scenarios tend to create dormant balances.

1. Closed Matters with Remaining Funds

When a matter closes, a small remainder is left behind in the trust account. This is often unintentional, but without clear documentation, many firms don’t take final steps to clear the remaining funds.

2. Clients Who Cannot Be Reached

Contact details change with time and firms may stop getting responses to emails and phone calls. Without a reliable way to return funds, balances remain in place longer than expected.

3. Disbursement Gaps

Estimated costs and actual expenses do not always align perfectly. Small differences can remain after reconciliation and may not be revisited once the matter concludes.

4. Administrative Delays

Refunds or follow-ups may be deferred during busy periods. What starts as a short delay can turn into a long-standing balance if there is no structured process or dedicated trust accounting software to bring it back into focus.

5. Incomplete Records or Context

When documentation is limited, it can be difficult to determine exactly how a balance should be handled. That uncertainty often leads to inaction.

Each of these situations is understandable on its own, but each can lead to bigger compliance risk without a consistent approach to reviewing and resolving inactive funds.

What Canadian Firms Are Expected to Do with Dormant Trust Funds

Across Canadian jurisdictions, Law Societies generally look for a clear, reasonable process that shows your firm has taken the responsibility seriously and followed through appropriately when a trust balance becomes dormant.

That process typically includes three core steps: investigation, resolution efforts, and documentation.

Step 1: Investigate the Source of the Balance

Start by understanding the origin of the funds and why they were left in the trust account. Review the matter history, billing activity, and any prior transactions to determine why the balance remains.

Clarity at this stage helps prevent incorrect assumptions and ensures that the next steps are grounded in accurate information.

Step 2: Make Reasonable Efforts to Resolve It

Once the context is clear, the next step is to take action. This may involve reaching out to the client, confirming instructions, or determining whether the funds can be applied appropriately.

If the client cannot be reached, continue making efforts to contact them. Reasonable effort means following a consistent approach to outreach and giving the process enough time to succeed.

Tip: A legal CRM that connects with your practice management and accounting tools can help automate client communications to make dormant balance follow-up easier for your team.

Step 3: Document Every Step Along the Way

Documentation is what turns reasonable effort into something your firm can demonstrate later for compliance purposes.

Your trust accounting records should reflect:

• When the balance was identified
• What actions were taken to investigate it
• How and when the client was contacted
• What decisions were made and why
• If further steps were required based on Law Society guidance

In some cases, if funds cannot be returned after reasonable effort, there may be formal procedures for handling them in accordance with regulatory expectations. The exact process depends on your jurisdiction.

What matters most is that your firm does not skip ahead or act without support. The key to trust compliance is being able to show that your firm approached the situation thoughtfully, consistently, and with clear records at every stage.

Common Mistakes That Create Compliance Headaches

Certain patterns tend to make resolution of dormant trust balances more complicated than it needs to be in a Canadian law firm.

Be aware of these five common mistakes that may lead to compliance issues later.

Delaying Action Until Context Is Lost

The longer a balance sits, the harder it becomes to understand its origin. Details fade, staff may change, and reconstructing the history of a remaining balance takes more effort than addressing it early would have required.

Making Adjustments Without Clear Records

Moving funds, writing off balances, or making corrections without proper documentation creates gaps in the trust record that are difficult to explain later. Even well-intentioned actions can raise concerns if they are not clearly recorded.

Treating Small Balances as Exceptions

It can be tempting to treat minimal amounts differently, but inconsistency creates risk. Every balance, regardless of size, should follow the same process to ensure full compliance.

Lacking a Defined Workflow

When there is no standard approach to managing trust accounts, three-way reconciliation, or dormant balances, each situation is handled differently and often irregularly. This makes it difficult to demonstrate a consistent compliance effort across the firm.

Failing to Track Outreach Efforts

If attempts to contact a client are not documented, there is no record showing that reasonable steps were taken. From a compliance standpoint, undocumented effort is indistinguishable from no effort at all.

How to Prevent New Dormant Trust Balances from Forming

The most effective way to deal with dormant balances is to reduce how often they appear in the first place. That comes down to building consistent habits into the way your firm closes matters and reviews trust activity.

Improve matter closeout discipline: A complete closeout process reviews trust balances, confirms that funds have been properly applied or returned, and ensures nothing is left unresolved.

Schedule regular trust reviews: A monthly or quarterly review of trust activity helps surface inactive funds before they become long-standing issues.

Standardise refund and follow-up processes: Clear internal steps for issuing refunds, contacting clients, and documenting actions help ensure that balances are handled consistently across the firm.

Keep client information up to date: Accurate contact details reduce the likelihood of funds becoming stuck due to communication breakdowns.

Assign clear ownership: Assigning ownership ensures that balances are reviewed, followed up on, and resolved rather than remaining in a shared queue.

Use dedicated trust accounting software: The right system can help your firm monitor balances, connect trust activity to matter records, and surface inactive funds before they become harder to resolve.

None of these steps require a major operational shift. But together, they create a system where fewer balances are left behind and fewer compliance questions arise later.
