When a relationship ends or a family matter becomes a legal one, the decisions you face can feel overwhelming. Whether you are navigating a separation, divorce, working through parenting arrangements, or trying to understand your rights around support and property, having the right legal guidance matters. In Ontario, family law matters are governed by the Family Law Act, the Divorce Act, the Children’s Law Reform Act, and the federal Child Support Guidelines. The rules that apply to your situation depend on whether you are married or in a common law relationship, and the choices you make early in the process have lasting consequences.

Cohen Highley LLP has served individuals and families across Southwestern Ontario since 1974. Our Sarnia office provides Lambton County residents with direct access to a full-service family law team. We handle matters at every level of complexity, from collaborative settlements to contested court proceedings.

Family Law Services We Offer

Our Sarnia family law team assists clients across the full range of matters that arise when relationships change. Whether your situation is relatively straightforward or involves high conflict, we provide clear legal advice and steady representation.

Our Approach to Family Law Matters

Every family law matter is different, and the right path forward depends on your circumstances, your goals, and the nature of the issues involved. At Cohen Highley, we begin with a thorough consultation to understand your situation, clarify your priorities, and give you an honest picture of your options. From there, we guide you through the necessary steps: gathering financial disclosure, pursuing negotiated settlements through direct negotiation, mediation, or collaborative law where appropriate, and preparing legally sound agreements that protect you going forward.

When resolution outside of court is not possible, we represent clients in the Ontario Superior Court of Justice, Family Court Branch, handling all aspects of proceedings from case conferences and motions through to trial. We also remain available after a matter is resolved, as support amounts, parenting arrangements, and other terms sometimes require adjustment when circumstances change.

We give clients honest advice and realistic expectations from the first consultation, so you can make informed decisions.
