Can a Lawsuit Continue When an Estate Has No Trustee in Ontario?

What happens to a lawsuit when an estate has no trustee in Ontario?

When an Ontario estate does not yet have a litigation trustee in place, the court must stay — meaning pause — all proceedings involving that estate. This is not a discretionary call; Rule 9.03 of the Ontario Rules of Civil Procedure makes it mandatory. In Dworak et al v. Romerein et al, 2026 ONSC 3389 (CanLII) (read the decision), the Superior Court confirmed this principle and stayed all proceedings until a proper representative is appointed.

If you are involved in a dispute that touches on an estate — whether as a creditor, a business partner, or a family member — understanding how this rule works can save you significant time and legal costs.

What is a litigation trustee and why does an estate need one?

A litigation trustee is a person authorized to represent an estate in court proceedings. Without one, the estate is not a proper legal party and cannot sue or be sued. When someone dies without a will — what lawyers call dying intestate — there is no executor named to step into that role automatically. Someone must apply to the court to be appointed as estate trustee before the litigation can move forward.

In the case at hand, the deceased died without a will. A parallel application had been filed in Newmarket to appoint an estate trustee, but that process was still ongoing at the time of the motion. Because no one had yet been formally appointed, the estate was not properly constituted, and the stay kicked in.

Does Rule 9.03 automatically stay all proceedings?

Yes — Rule 9.03 of the Ontario Rules of Civil Procedure operates automatically once it is clear that an estate lacks a proper litigation trustee. The court in this case confirmed that the stay applies to all proceedings by or against the estate, not just selected claims. There is no judicial discretion to carve out exceptions while the estate remains unrepresented.

This is an important distinction. Parties sometimes assume they can keep pushing forward on certain issues while the trustee appointment is sorted out. The court’s ruling makes clear that is not how the rule works.

Can the court still deal with other issues during the stay?

Generally, no — and that is exactly what happened here. One party sought interim injunctive relief related to the management of company properties. The request was essentially asking the court to authorize changes to how a business was being run while the estate dispute was pending. The court declined, noting there was no existing court order concerning the company and that the stay prevented it from granting that kind of relief.

Requests for mediation were also set aside. The court deferred all of these matters to a future comeback motion. The only question left open for that motion was the narrower issue of whether a litigation trustee should be appointed and, if so, who should fill that role.

What is a comeback motion in Ontario civil litigation?

A comeback motion is a follow-up court appearance that is scheduled when a judge deals with an urgent or preliminary matter but leaves certain questions unresolved. Rather than deciding everything at once, the court sets a future date where the remaining issues can be argued properly, with full materials and proper notice.

In this case, the comeback motion was limited in scope: the parties would return to address the litigation trustee question specifically. The broader issues — including the corporate management dispute and the constitution of the estate — were not to be relitigated at that appearance.

How does an intestate estate affect a corporate dispute in Ontario?

When a deceased person held shares or had a management role in a company, their death without a will can create real uncertainty about who speaks for their interest in that business. Until an estate trustee is appointed, no one has the legal authority to make decisions on behalf of the estate — including decisions about company property or management.

That uncertainty was at the heart of this case. The parties were in a dispute involving company properties, but because the estate was not yet properly constituted, the court could not authorize any changes to how those properties were managed. Disputes involving both an estate and a corporation can become particularly complex, and getting proper legal advice early is critical. Our Ontario employment lawyers regularly advise clients on disputes where business relationships and estate issues intersect.

Practical takeaways for estate dispute parties

• Act quickly on trustee appointment. If a key party to your dispute has died without a will, the clock starts immediately. Filing an application to appoint an estate trustee as soon as possible prevents prolonged delays caused by the automatic stay.
• Do not assume partial proceedings can continue. Rule 9.03 stays everything — injunctions, mediation orders, and management authorizations are all off the table until the estate has a proper representative.
• Identify the comeback motion scope early. Courts will often limit what can be argued at the follow-up hearing. Know exactly what is and is not on the table before you spend resources preparing broad arguments.
• Get independent advice on corporate interests. If the estate holds shares or a management role in a company, a co-owner or business partner should seek their own legal counsel rather than waiting for the estate process to resolve itself.
• Document the status of any existing court orders. As this case illustrates, the absence of a prior court order about a company can limit what relief is available during a stay. Keep clear records of what orders do and do not exist.
