In Ontario, a common-law relationship refers to a partnership where two individuals live together and share a life without being formally or legally married couples. The province recognizes the rights and responsibilities of common-law partners under the Family Law Act. According to this legislation, individuals are considered common-law spouses if they have lived together continuously for at least three years, or if they are in a relationship of some permanence and have a child together. This legal recognition aims to ensure fair treatment and protection for individuals in common-law relationships within the framework of family law in Ontario.


The common law spouses have various rights upon separation, some of which are discussed below.


Exclusive possession

In both formal marriages and common-law relationships, the question of exclusive possession of the shared residence is a pivotal consideration during separation. Section 24 of the Family Law Act grants the court the authority to provide exclusive possession based on factors such as the best interests of the children, irrespective of the formal nature of the relationship. Notably, the rights regarding the matrimonial home may be less defined compared to property owned by married couples. While the act permits common-law spouses to seek exclusive possession, the process and criteria differ, marking an initial distinction in the legal treatment of property rights between the two relationship types.


The division of property in the absence of a formal marriage contract involves a meticulous examination of shared assets and debts. Unlike married couples who have an automatic right to equalize their net family property, common-law partners must navigate a less structured legal landscape. Clear agreements or legal interventions aid to ensure an equitable division of property for common-law spouses.


The equalization of net family property, a central tenet of marital divorce under Section 5(1) of the FLA, is not directly applicable to common-law couples. While married spouses are entitled to an automatic equalization of their net family property upon divorce, common-law partners do not benefit from this streamlined process. Instead, they may need to pursue legal mechanisms such as constructive trust claims to achieve a fair distribution, highlighting a notable divergence in the rights of common-law and married spouses.


The determination of child support payments in common law marriage follows FLA guidelines, primarily relying on the income of the paying parent to ensure a consistent standard of living for the child. The overarching principle of the best interests of the child governs this process, taking into account factors such as the child’s specific needs and the standard of living during the parents’ relationship. Importantly, child support rights and obligations are uniformly applicable to both common-law and married couples, emphasizing equality for children irrespective of their parents’ marital status. In common-law relationships, enforcement mechanisms, including wage garnishments, property seizure, and filing a notice of default, provide avenues to ensure that child support orders are effectively implemented. This underscores the importance of comprehending the unique considerations within common-law unions and establishing robust enforcement measures to guarantee the ongoing financial support crucial for the child’s well-being.


Spousal support considerations apply universally, encompassing both common-law and married relationships. However, the formalities of marriage provide a more structured legal framework for determining spousal support in divorces. While common-law spouses have the same rights to spousal support, they may need to navigate a less defined legal landscape compared to their married counterparts.

The spousal support determinations are guided by several key factors:

•    Length of the Relationship: The duration of the relationship is a crucial factor. In Ontario, a longer relationship may result in a lengthier period of spousal support.

•    Roles and Contributions: The FLA acknowledges the various roles each party played during the relationship. Contributions, whether financial or non-financial, are considered when determining the need for and amount of spousal support.

•    Economic Consequences: The economic consequences of the separation agreement, including disparities in income and the standard of living, are fundamental considerations.


Within common-law separations in Ontario, child custody and access arrangements are governed by Section 20 of the Children’s Law Reform Act. This pivotal provision places the best interests of the child at the forefront, considering factors such as emotional and physical well-being, the child’s views, parental abilities, and relevant circumstances. This Court has the authority to determine various types of custody, including sole, joint, or shared custody, while also ensuring access rights for the non-custodial parent. The emphasis on flexibility and a case-specific approach underscores the tailoring of custody and access arrangements to each family’s unique circumstances, all with the overarching goal of safeguarding the well-being of the child.


When navigating the complexities of common-law separation, seeking professional legal assistance is crucial at various junctures. If you find yourself contemplating separation, it’s advisable to seek legal advice and consult with a family law attorney early in the process. Their guidance can provide clarity on your rights, potential outcomes, and the steps involved in the separation. Legal assistance becomes especially crucial when addressing matters like property division, spousal support, and child custody, ensuring that your interests are safeguarded and the best interests of any children involved are prioritized.

Moreover, seeking help promptly can facilitate smoother negotiations and, if necessary, legal proceedings. As emotions run high during separations, having a legal advocate provides a rational and objective perspective, helping you make informed decisions that will shape your future post-separation. Whether you are at the initial stages of contemplating separation or facing challenges in ongoing negotiations, timely legal support is instrumental in achieving equitable and favorable outcomes.


In conclusion, the landscape of common-law separation in Ontario is marked by both shared principles and distinctive challenges. From the less structured division of property to the absence of automatic equalization, common-law spouses navigate a legal terrain that demands careful consideration and proactive legal action. Understanding these differences is paramount for individuals in common-law relationships, underscoring the need for legal counsel to effectively navigate the complexities of family law in Ontario.
