When a loved one passes away, their executor (the person named in the will to manage the estate) steps into a huge responsibility. They must pay bills, manage assets, and distribute property to beneficiaries. Sounds straightforward, right?

Not always.

One Ontario case, Zimmerman v. McMichael Estate, shows exactly what can go wrong when executors don't keep proper records. The court's message was clear: executors must document everything, or risk personal consequences.

What Happened in Zimmerman v. McMichael Estate?

At the heart of the Zimmerman case was a simple, but critical, problem: the executor had not kept proper records of how estate assets were handled. Beneficiaries grew suspicious that money had been mishandled, and when they asked for an accounting, the executor could not produce satisfactory documentation.

The court ultimately found that this lack of transparency was unacceptable. Executors are fiduciaries, meaning the law requires them to act with honesty, care, and loyalty to the beneficiaries. That duty includes maintaining a clear record of every decision and transaction made on behalf of the estate. Without proper documentation, the executor could not prove that they had fulfilled their obligations.

What This Means for Executors

The Zimmerman case serves as a cautionary tale for anyone serving as an executor. Even if an executor is acting in good faith, failing to keep proper records can backfire. Without receipts, statements, or written explanations, beneficiaries may begin to question whether funds were used appropriately. Once trust is lost, disputes are far more likely to end up in court.

Executors must remember that they can be held personally accountable if they cannot justify their decisions. In the Zimmerman case, the court made it clear that the burden of proof rests on the executor, not the beneficiaries. This means that careful and consistent record-keeping is not just best practice – it is essential for protecting both the estate and the executor.

How Good Records Protect Families

Keeping good records benefits everyone involved in the estate process. For executors, proper documentation provides a shield against false accusations or misunderstandings. It allows them to show, step by step, that they carried out their duties responsibly and in line with the law.

For beneficiaries, good records build confidence in the process. They can see exactly how assets are being managed and distributed, which reduces suspicion and helps preserve family relationships at a time when emotions may already be strained. Most importantly, proper record-keeping prevents unnecessary litigation, saving the estate both time and money!

How Executors Can Stay on Track

Being an executor can feel overwhelming, especially if it's your first time taking on the role. The reassuring news is that you don't have to navigate it alone. Keeping receipts, bank records, and important correspondence together in one place goes a long way in staying organized, and offering regular updates to beneficiaries helps build trust and keep the process running smoothly.

If you feel unsure about the process, it's completely normal to reach out to a lawyer or accountant for guidance. They can take some of the weight off your shoulders and make sure everything is done properly. By staying organized and asking for help when needed, you can carry out your duties with confidence and peace of mind.

The Takeaway from Zimmerman v. McMichael Estate

The lesson from this case is straightforward: record-keeping is not optional. Executors must document every action they take in administering an estate. Doing so protects them from liability, reassures beneficiaries, and ensures that the wishes of the deceased are respected.
