Toronto Divorce Lawyer & Conflict of Interest: What to Know

What Is a Conflict of Interest in Divorce Cases?

In Ontario, the role of a divorce lawyer is governed by both provincial family law statutes and the ethical rules set by the Law Society of Ontario. A conflict of interest arises when a lawyer’s ability to represent a client is compromised by a duty owed to another person—often a former or current client—or by the lawyer’s own interests. When this occurs in the emotionally and financially sensitive realm of family law, the consequences can be serious.

Definition under Ontario Family Law

A conflict of interest in divorce cases typically refers to a situation where the lawyer’s loyalty or independent judgment may be impaired. According to Ontario’s Rules of Professional Conduct, lawyers must avoid situations where there’s a “substantial risk” that their representation of one client would be “materially and adversely affected” by their duties to another client, a third party, or their own personal interests.

In divorce law, where trust, confidentiality, and strategic negotiation are critical, even the appearance of divided loyalty can be enough to disqualify a lawyer from continuing on a file.

Examples of Common Conflicts in Divorce Representation

  • Representing Both Spouses: One of the most direct and prohibited conflicts occurs when a lawyer attempts to represent both spouses in a divorce. Even if both parties insist they’re amicable and want to save money, Ontario law prohibits this due to the inevitable divergence in legal interests (e.g., spousal support, custody, property division). Instead, couples may jointly retain a mediator, but each party should retain their own lawyer to review any agreement.
  • Previous Involvement with the Other Party: A lawyer who has previously represented your spouse—or even had a prior professional relationship with them (such as in a real estate transaction or business matter)—may be considered conflicted out of your case. If the lawyer had access to confidential information, they may be disqualified from acting against the former client.
  • Family or Business Ties: A divorce lawyer who is related to the opposing party, shares office space with their lawyer, or has business dealings with either side may also face a conflict of interest. In such cases, the perception of bias can damage the client’s trust and lead to appeals or motions to remove the lawyer.

The Duty of Loyalty and Confidentiality in Divorce Representation

A divorce lawyer’s duty of loyalty means they must always act in the best interests of their client—without exception. Once retained, a lawyer must not place themselves in a position where their commitment to the client is compromised. This includes avoiding actions that could inadvertently benefit the opposing spouse.

The duty of confidentiality is equally vital. Anything a client tells their lawyer in the context of legal advice is protected by solicitor-client privilege. If a lawyer has previously received confidential information from one spouse, they cannot ethically or legally use it when representing the other. Breaching this duty could result in disciplinary action, disqualification from the case, or legal claims of professional misconduct.

 

How Toronto Divorce Lawyers Screen for Conflicts

In Toronto, divorce lawyers are ethically obligated to ensure that they can act in their client’s best interests without any divided loyalty or risk of breaching confidentiality. This is why screening for conflicts of interest is one of the first and most important steps a divorce lawyer takes before accepting a new client. Failure to conduct proper checks can result in serious legal and professional consequences.

Initial Conflict Checks before Accepting a Client

When a potential client contacts a Toronto divorce lawyer, the firm conducts an initial conflict check before proceeding with a full intake or offering legal advice. This process typically includes:

  • Checking internal databases for any prior involvement with the potential client’s spouse, in any legal capacity.
  • Reviewing previous consultations, even if the lawyer never formally represented the spouse—because confidential information may have been shared during those meetings.
  • Cross-referencing associated parties, such as family members, business partners, or co-parents, to ensure there’s no indirect conflict.

Many Toronto law firms use practice management software to automate this process, but smaller practices may rely on manual systems. Regardless of the method, the goal is to avoid any situation where the lawyer’s objectivity or loyalty could be compromised.

Law Society of Ontario Guidelines on Ethical Conduct

The Law Society of Ontario (LSO) enforces strict rules regarding conflicts of interest through its Rules of Professional Conduct. According to Rule 3.4 of the LSO guidelines:

  • A lawyer must not act or continue to act where there is a conflict, unless the clients involved provide informed consent and the lawyer reasonably believes they can act without compromising duties.
  • Even with consent, a conflict is non-waivable in many family law cases—particularly in divorce—because of the high likelihood of adverse interests.
  • Lawyers are also advised to decline representation if there’s any substantial risk of misuse of confidential information from a former client.

What Clients Should Disclose During Intake

Clients play a critical role in the conflict-screening process. During the intake interview, clients are expected to fully and honestly disclose:

  • The full name of their spouse or ex-spouse
  • Any past dealings (legal or otherwise) that either spouse may have had with the law firm
  • Shared assets, business partnerships, or third parties that may be involved in the divorce
  • Prior consultations with other lawyers—even if no retainer was signed—so the new lawyer can confirm that they’re not duplicating a conflict

Withholding information, whether intentionally or unintentionally, can derail a case and potentially force a lawyer to withdraw mid-process, causing costly delays.

 

Signs Your Divorce Lawyer May Be Conflicted

A divorce lawyer’s primary responsibility is to advocate for your best interests with loyalty, confidentiality, and undivided attention. When a conflict of interest exists—especially one that goes undetected or undisclosed—it can negatively impact the quality of your legal representation. Clients in Toronto should be aware of warning signs that suggest their divorce lawyer may be conflicted.

Unexplained Delays or Vague Advice

One of the first red flags that may point to a conflict is a pattern of vague or non-committal advice. If your lawyer avoids giving clear guidance on important decisions—such as property division, child custody strategy, or settlement negotiations—it may be a sign they’re hesitant due to conflicting loyalties.

Similarly, unusual delays in responding to your emails, preparing court documents, or scheduling meetings without a reasonable explanation could suggest internal discomfort or a legal complication related to the other party.

In some cases, lawyers may stall because they’re trying to quietly resolve an internal conflict before it’s formally identified or challenged by the court.

Unequal Advocacy or Divided Attention

A Toronto divorce lawyer should be fully focused on your side of the case. If you start noticing signs that your lawyer:

  • Minimises your concerns or avoids addressing critical points,
  • Fails to challenge the opposing party’s claims assertively,
  • Recommends concessions that seem one-sided or against your best interests,

…it could indicate divided loyalties.

This is especially concerning if your spouse seems to have inside knowledge about your case strategy or if your lawyer appears overly cooperative with opposing counsel, particularly if they have a close working relationship or past connection.

Discovery of Prior Dealings with the Other Party

Perhaps the clearest sign of a potential conflict of interest is the discovery that your lawyer had a prior relationship with your ex-spouse or their legal representative. This might include:

  • Having previously represented your spouse in any legal matter (even unrelated)
  • Social or business connections to the other party or their family
  • Working at the same firm as your spouse’s lawyer or sharing office resources

Even if the relationship was informal or occurred years ago, it could still compromise your case—especially if your lawyer had access to confidential information or insights that now create an ethical dilemma.

When this happens, you have every right to question your lawyer and, if necessary, request a formal conflict check or even a new lawyer. In some situations, the court may intervene and require the conflicted lawyer to withdraw from the case entirely.

 

Legal and Ethical Consequences of Conflicted Representation

Breach of Fiduciary Duty and Professional Misconduct

A divorce lawyer owes a fiduciary duty to act with undivided loyalty, honesty, and integrity toward their client. When a lawyer represents a client while having a conflicting relationship or prior duty to the opposing party, this fiduciary duty may be breached. Under Ontario law, this constitutes professional misconduct, which is regulated and enforced by the Law Society of Ontario.

If a conflict is proven, the lawyer may face:

  • Disciplinary proceedings initiated by the Law Society
  • Suspension or revocation of their licence
  • Civil liability if the client suffered harm due to the conflicted representation

These ethical rules are designed to ensure public confidence in the legal profession and to protect clients from compromised representation during sensitive family matters.

Possible Case Dismissal or Court Challenges

For clients, being represented by a lawyer with a conflict of interest can seriously jeopardize the outcome of their divorce case. Some of the potential consequences include:

  • Motions to remove the lawyer from the case, resulting in delays and additional legal costs
  • Suppression of evidence or voided agreements if the court finds that privileged information was misused
  • Dismissal of claims or appeals, especially if the conflict distorted the fairness of proceedings

Courts take these matters seriously because they go to the heart of due process. If the court determines that the client’s position was unfairly compromised, it may reopen the file, vacate previous orders, or require the parties to start over with new representation.

When Toronto Courts May Disqualify a Lawyer

Toronto family courts have the authority to disqualify a divorce lawyer if a conflict of interest is found. Disqualification is more likely in cases where:

  • The lawyer previously represented the opposing party in a related or sensitive matter
  • The lawyer had access to confidential information that could now be used against the former client
  • Continuing representation would risk undermining the integrity of the legal process or cause significant prejudice to either party

Courts may also consider public perception, particularly if the lawyer’s involvement raises concerns about fairness or impartiality in the family justice system.

 

What to Do If You Suspect a Conflict of Interest

If you’re involved in a divorce and begin to suspect that your lawyer may have a conflict of interest, it’s essential to take action promptly. Whether the concern is based on instinct or supported by evidence, addressing the issue early can help protect your legal rights and ensure your case is not compromised. In Toronto, there are formal steps you can take to resolve these concerns effectively.

Steps to Raise Concerns with Your Lawyer

Start by communicating your concerns directly and clearly with your lawyer. Approach the matter professionally and request an explanation. You can say:

  • “I’d like to confirm that there are no prior relationships or professional dealings between you and my former spouse.”
  • “Have you conducted a full conflict check regarding my ex-partner and their legal counsel?”

A reputable Toronto divorce lawyer will take your concern seriously and should be willing to disclose any potential issues. If your lawyer is defensive, evasive, or dismisses your concerns without a thorough explanation, consider that a red flag.

When to Request a Change in Representation

If you continue to feel uneasy or discover a confirmed conflict, it may be in your best interest to terminate the lawyer-client relationship and seek new counsel. Some scenarios that warrant an immediate change include:

  • Evidence that the lawyer previously represented your spouse
  • Discovery that your lawyer has a personal relationship with the opposing party
  • Perceived favouritism or reluctance to advocate assertively on your behalf

In Ontario, you can formally discharge your lawyer by signing a Notice of Change in Representation or by hiring a new lawyer who will file the notice on your behalf.

It’s important to make the transition carefully—ensure all your case files and documentation are securely transferred to your new legal representative to avoid delays in court proceedings.

Filing a Complaint with the Law Society of Ontario

If you believe your lawyer has acted unethically or breached their professional obligations, you have the right to file a complaint with the Law Society of Ontario (LSO). This regulatory body oversees all licensed lawyers in the province and investigates allegations of:

  • Conflicts of interest
  • Breach of confidentiality
  • Misuse of privileged information
  • Failure to act with loyalty and competence

You can file a complaint online via the LSO’s website or by submitting written documentation. Be prepared to provide supporting materials such as emails, meeting notes, or court documents that outline your concerns.

The LSO may take steps including:

  • Investigating the conduct in question
  • Issuing warnings or fines
  • Suspending or disbarring the lawyer if serious misconduct is confirmed

 

Protecting Your Case and Confidentiality

Switching to an Independent Divorce Lawyer in Toronto

If you decide to replace your current lawyer due to a conflict of interest, the next step is to retain a completely independent divorce lawyer with no prior ties to your ex-spouse, their legal team, or any related parties. Look for a Toronto divorce lawyer who:

  • Conducts thorough conflict checks before taking your case
  • Has no shared history with the opposing side or your former counsel
  • Clearly explains your legal options and case status moving forward

Once retained, your new lawyer will file a Notice of Change in Representation with the court and request your file from the previous lawyer. This allows for a seamless transition while maintaining procedural timelines.

It’s also wise to inform the court or opposing counsel (through your new lawyer) that a conflict was identified and that you’ve secured fresh representation to protect the fairness of the proceedings.

Importance of Clear Retainer Agreements

A retainer agreement is a binding contract between you and your divorce lawyer that outlines the terms of the professional relationship. When working with new counsel, ensure the retainer includes:

  • A declaration that no conflict of interest exists
  • A confidentiality clause protecting all communications
  • A detailed breakdown of fees, scope of services, and dispute resolution procedures

Having a strong retainer in place can prevent future misunderstandings and reinforce the ethical framework of your legal representation.

Reputable divorce lawyers in Toronto will walk you through this agreement carefully and answer any questions you have before proceeding.

How to Secure Sensitive Information during the Transition

When switching lawyers, protecting sensitive documents and communications is crucial. Here are a few steps to take:

  • Request your full client file from the previous lawyer, including all court documents, financial disclosures, communications, and notes. You are legally entitled to this information, even if you owe outstanding fees.
  • Keep a copy of everything for your own records, both physical and digital.
  • Change your passwords if your former lawyer had access to any shared drives, cloud storage, or confidential communication platforms.
  • Review all prior communications between your former lawyer and the opposing party—your new lawyer can help assess whether any privileged information may have been compromised.

If you suspect that sensitive information was misused, your new lawyer can file a motion with the court to have certain evidence excluded or to seek other protective remedies.
