Top Mistakes to Avoid During Family Court Proceedings in Ontario
Navigating family court proceedings can be one of the most stressful experiences a person will face. Whether your matter involves parenting arrangements, decision-making responsibility, child or spousal support, or property division, the choices you make during the process can have long-lasting consequences.
As a family lawyer practising in Ontario, I often see clients unintentionally harm their own case by making avoidable mistakes. Understanding what not to do is just as important as knowing what steps to take.
Below are some of the most common mistakes to avoid during family court proceedings in Ontario.

1. Letting Emotions Drive Decisions
Family law matters are deeply personal, and emotions often run high. While feelings of anger, frustration, or fear are understandable, allowing them to dictate your actions can negatively impact your case.
Ontario courts prioritize reasonableness, cooperation, and the best interests of the child. Emotional reactions such as hostile communications, impulsive decisions, or refusal to compromise can undermine your credibility and make resolution more difficult.
2. Failing to Disclose Financial Information Fully and Honestly
Full and frank financial disclosure is a legal requirement in Ontario family law proceedings. Attempting to hide income, undervalue assets, or delay disclosure can seriously damage your case.
Incomplete or misleading disclosure may result in:
- Court sanctions
- Adverse cost awards
- Court-imposed decisions that may not be in your favour
Transparency is essential, particularly in matters involving support or equalization of net family property.
3. Ignoring Court Orders or Temporary Agreements
Court orders and temporary arrangements are legally binding, even if you disagree with them. Failing to comply such as withholding support payments or not following parenting schedules can result in enforcement proceedings and harm your standing before the court.
If circumstances change, the appropriate step is to seek a formal variation, not to act unilaterally.
4. Posting on Social Media
Social media posts are frequently used as evidence in family court. Photos, comments, or messages shared online can be taken out of context and used to challenge your credibility, financial claims, or parenting abilities.
As a general rule, it is best to limit or completely avoid posting on social media while your matter is ongoing.
5. Poor Communication With the Other Party
Unnecessary conflict, aggressive emails, or inappropriate text messages can escalate disputes and reflect poorly on you in court. Judges in Ontario expect parties to communicate respectfully, particularly where children are involved.
When possible, keep communications:
- Child-focused
- Polite and factual
- In writing, and free from emotional language
6. Not Focusing on the Best Interests of the Child
In parenting matters, the court’s primary consideration is the best interests of the child, not the preferences or grievances of either parent.
Actions that prioritize conflict over cooperation such as involving children in disputes or speaking negatively about the other parent can be harmful to both your case and your child’s well-being.
7. Attempting to Handle Complex Matters Without Legal Advice
While some individuals consider self-representation to save costs, family law is complex and procedural mistakes can be costly. Missing deadlines, filing incorrect documents, or misunderstanding your legal rights can lead to unfavourable outcomes.
Even if you do not intend to retain a lawyer for the entire process, obtaining legal advice early can help you avoid critical errors and understand your options.
Final Thoughts
Family court proceedings are challenging, but many common mistakes are preventable with the right guidance and preparation. Remaining organized, respectful, and informed can significantly improve both the outcome of your case and your overall experience.
If you are involved in a family law matter or anticipate future proceedings, speaking with an experienced Ontario family lawyer can help you navigate the process with clarity and confidence.
