Adultery can be one of the most emotionally difficult issues in a separation. For many spouses, discovering an affair changes how they understand the relationship and can raise questions about fairness, especially where one spouse may later seek spousal support.
In British Columbia family law, however, the emotional importance of adultery is different from its legal relevance. Spousal support is generally not intended to punish a spouse for the breakdown of a relationship. Instead, the focus is usually on financial need, ability to pay, economic disadvantage, and the roles the spouses had during the relationship.
For separating spouses in Vancouver and across BC, adultery may explain why the relationship ended, but it does not necessarily determine whether support will be paid, how much will be paid, or how long it will continue.
Spousal Support Is About Finances, Not Fault
Spousal support is money paid by one spouse to the other after separation or divorce. It may apply to married spouses and, in some circumstances, unmarried spouses who lived together in a marriage-like relationship. In BC, support may arise under the federal Divorce Act or BC’s Family Law Act.
The central question is generally not who caused the relationship to end. Instead, the analysis considers whether one spouse is entitled to support and, if so, the appropriate amount and duration.
Even where adultery occurred, the focus typically returns to financial realities. Did one spouse experience economic disadvantage because of the relationship? Did caregiving, unpaid work, or career sacrifices benefit the other spouse? Does one spouse need support, and does the other have the ability to pay?
Canada’s No-Fault Approach to Divorce
Most Canadian divorces proceed after spouses have lived separately and apart for at least one year. Although adultery can be a ground for divorce under the Divorce Act, proving adultery is unnecessary in most cases.
This no-fault approach also shapes spousal support. A spouse who had an affair is not automatically barred from receiving support, and the spouse who was betrayed is not automatically relieved of an obligation to pay it. Family law generally separates the reasons a relationship ended from the financial consequences of the relationship and separation.
What the Divorce Act Says About Misconduct
For married spouses, the Divorce Act expressly provides that the court must not consider marital misconduct when making a spousal support order.
As a result, adultery itself is generally not a deciding factor. Instead, the Court considers matters such as the condition, means, needs, and circumstances of each spouse, including the length of the relationship, the spouses’ respective roles, the financial consequences of caregiving, and the goal of encouraging economic self-sufficiency where reasonable.
What BC’s Family Law Act Says
BC’s Family Law Act similarly focuses on the economic consequences of a relationship and its breakdown. Its objectives include recognizing economic advantages and disadvantages, addressing financial consequences arising from child care, relieving economic hardship, and promoting self-sufficiency where appropriate.
Although the Act contains provisions concerning misconduct, not every form of bad behaviour becomes relevant to support. The key issue is generally whether particular conduct has a meaningful connection to financial need, ability to pay, or the broader support analysis. Adultery by itself will therefore rarely change the result.
When Conduct May Become Financially Relevant
While adultery itself is usually not determinative, conduct associated with an affair can become relevant when it affects the spouses’ finances. For example, issues may arise if significant family funds were spent on an affair, assets were depleted, debts were incurred, or financial information was hidden. These matters may be legally relevant because of their financial consequences, rather than because of the affair itself.
The distinction is important: family law generally focuses on economic impact, not moral blame.
Adultery and Property Division
Spousal support and property division are separate issues. Property division concerns how family property and family debt are divided, while spousal support addresses ongoing or lump-sum financial assistance between spouses.
Adultery itself does not normally determine who receives the family home, who keeps particular assets, or how debts are divided. However, if one spouse has depleted family assets or otherwise affected the financial picture, that conduct may need to be addressed as part of the property analysis.
Adultery and Parenting Arrangements
Adultery also does not generally determine parenting arrangements. In BC, parenting decisions are based on the best interests of the child.
Having an affair does not necessarily say anything about a parent’s ability to care for a child or maintain a meaningful relationship with them. Conduct may become relevant, however, if it affects the child’s safety, stability, emotional well-being, or care. This means that separating spouses must often distinguish between hurtful conduct within the adult relationship and conduct that has a direct impact on parenting.
Common Misconceptions About Adultery and Support
A spouse who had an affair does not automatically lose the right to seek spousal support. If that spouse otherwise has a valid claim based on the financial circumstances of the relationship and separation, adultery will not necessarily defeat it.
Likewise, the spouse who was betrayed does not automatically receive more support or pay less support. The analysis remains focused on entitlement, amount, duration, need, means, and economic consequences.
Proving adultery may also do little to change the financial outcome of a family law dispute. In some cases, focusing heavily on fault can increase conflict, cost, and delay without affecting the legal result.
Practical Considerations After Separation
For spouses dealing with adultery and separation, it can help to separate emotional concerns from legal and financial questions.
Financial disclosure is often more important than proving fault. Income, assets, debts, expenses, employment history, caregiving roles, and future earning capacity may all affect support. Where there are concerns that money has been improperly spent or financial information is being withheld, documentation can become particularly important.
Support may ultimately be resolved through negotiation, mediation, collaborative processes, a separation agreement, or court proceedings, depending on the circumstances.
The Vancouver Family Law Perspective
In Vancouver, separation frequently occurs alongside significant financial pressures, including high housing costs, complex property interests, business ownership, professional income, and family debt.
Against that backdrop, the financial consequences of separation may have much greater legal significance than the personal reasons the relationship ended.
Adultery may be part of the story, but entitlement to spousal support will generally depend on the nature of the relationship, the spouses’ economic roles, their current circumstances, and the financial consequences of separation.
