What Does a Family Lawyer Actually Do in Ontario?

Most people only search for a family lawyer when they are already in crisis — a marriage breaking down, a custody dispute escalating, or a separation agreement that keeps getting delayed. But understanding what a family lawyer does before you need one can save you significant time, money, and emotional energy.

At Rohr Law Professional Corporation, our experienced family lawyers in Oshawa work with individuals and families across Durham Region to navigate some of the most personal and consequential legal situations of their lives. Whether you are preparing for separation, protecting your parental rights, or resolving a long-standing property dispute, a qualified Ontario family lawyer is your most important asset.

This guide explains exactly what a family lawyer does, when you need one, and what to expect when you work with our team in Oshawa.

What Is Family Law in Ontario?

Family law in Ontario governs the legal rights and obligations that arise from family relationships — including marriage, separation, divorce, parenting, and financial support. It is primarily regulated by two pieces of legislation:

The Family Law Act (Ontario) — which governs property division, spousal support, and domestic contracts for Ontario residents.

The Divorce Act (Federal) — which governs divorce proceedings, parenting orders, and child support for married spouses.

Additionally, the Children’s Law Reform Act (Ontario) governs parenting matters for unmarried parents in Ontario. Understanding which law applies to your situation is one of the first things a family lawyer helps you determine.

What Does a Family Lawyer Actually Do?

A family lawyer provides legal advice, drafts and reviews legal documents, represents clients in negotiations and court proceedings, and ensures their client’s rights are protected throughout the family law process. Here is a breakdown of the core areas they handle in Ontario:

1. Divorce and Separation

When a marriage breaks down, a family lawyer guides you through the legal process of either separating or obtaining a formal divorce under the Divorce Act. This includes advising on grounds for divorce (in Canada, the only ground is marriage breakdown, proven by one year of separation, adultery, or physical or mental cruelty), filing the necessary court documents, and negotiating a settlement on all related issues.

In Ontario, separation begins when spouses decide to live separately and apart — they do not need a court order to be legally separated. However, having a properly drafted separation agreement is critical to protecting your rights. Our Oshawa family lawyers help you understand your options and move forward with clarity.

2. Parenting Time and Decision-Making Responsibility

Since the Divorce Act was amended in 2021, Ontario family law no longer uses the terms ‘custody’ and ‘access.’ Instead, the framework focuses on ‘parenting time’ (when each parent spends time with the child) and ‘decision-making responsibility’ (who makes important decisions about the child’s education, health, religion, and extracurricular activities).

A family lawyer helps parents develop parenting plans that serve the best interests of the child — the paramount consideration under both the Divorce Act and the Children’s Law Reform Act. When parents cannot agree, a family lawyer represents their client in court to seek fair and workable parenting arrangements.

3. Child Support

Child support in Ontario is calculated according to the Federal Child Support Guidelines, which are based on the paying parent’s gross annual income and the number of children. A family lawyer ensures that support is calculated correctly, that both parties provide full financial disclosure, and that the order is enforceable.

You can access the Federal Child Support Guidelines through the Government of Canada’s website. Your lawyer will apply these guidelines to your specific income and parenting arrangement.

4. Spousal Support

Spousal support is not automatic in Ontario — entitlement depends on factors such as the length of the marriage, each spouse’s income and earning capacity, and the roles each played during the relationship. The Spousal Support Advisory Guidelines (SSAGs) are used to calculate the range and duration of support, though they are not legally binding.

A family lawyer analyzes your specific circumstances to determine whether you are entitled to support, how much, and for how long — and they advocate on your behalf during negotiations or court proceedings.

5. Property Division and Equalization

Under Ontario’s Family Law Act, married spouses are entitled to equalization of net family property at the end of a marriage. This means each spouse’s net worth gained during the marriage is calculated, and the spouse with the higher net family property pays the other spouse half the difference.

This process can be complex, especially when it involves the matrimonial home, business interests, pension plans, inheritances, or debts. A family lawyer ensures all assets and liabilities are properly disclosed and valued.

6. Separation Agreements and Domestic Contracts

A separation agreement is a legally binding contract signed by both spouses that resolves all issues arising from their separation — including parenting, support, and property division. A properly drafted separation agreement can avoid costly and time-consuming court proceedings.

Family lawyers also draft cohabitation agreements and marriage contracts (prenuptial agreements), which can protect both parties’ financial interests before or during a relationship.

When Do You Need a Family Lawyer in Ontario?

You should consult a family lawyer as early as possible — ideally before you separate, or as soon as the separation becomes clear. Here are the key situations that require professional legal advice:

• You are separating from a spouse or common-law partner in Ontario
• You have children and need to establish parenting arrangements
• You need to determine or enforce child or spousal support
• You and your spouse have significant assets, debts, or property to divide
• Your spouse has already retained a lawyer
• You have a business interest that could be considered family property
• You are dealing with domestic violence or safety concerns
• You want to create or review a separation agreement, cohabitation agreement, or marriage contract

The earlier you get legal advice, the better positioned you are to make decisions that protect your long-term financial security and parenting relationship.

Can You Handle Family Law Matters Without a Lawyer in Ontario?

Technically, yes — Ontario law does not require you to have a lawyer in family law proceedings. However, proceeding without legal representation carries significant risks. Without proper legal advice, you may unknowingly sign an agreement that is unfair, unenforceable, or that fails to address important issues. Mistakes made early in the separation process can be costly or impossible to reverse.

Ontario does offer resources for self-represented litigants, including the Ontario Court of Justice, the Superior Court of Justice, and the Family Law Information Centre (FLIC) available at courthouses. However, these resources provide information — not legal advice tailored to your situation.
