Key takeaways
  • Separation for divorce purposes is based on how you have lived, not on a court filing.
  • Court is needed to obtain a divorce, which is handled in the Court of King's Bench, Family Division.
  • A domestic contract such as a separation agreement must be in writing, signed by the parties to be bound, and witnessed, and it generally prevails over a conflicting provision of the Marital Property Act.

Ending a relationship feels like it should come with an official step. In New Brunswick, many people are surprised to learn that separating and getting a divorce are different things. You may be separated for a long time before any court is involved.

This article explains what the law looks at when it asks whether you are separated, when a court becomes necessary, and how agreements can help. It also covers common-law partners, who are in a different position from married spouses.

This article covers the law of New Brunswick.

Separation is mostly about how you live

For divorce purposes, breakdown of the marriage is generally established if spouses have lived separate and apart for at least one year immediately before the divorce proceeding is determined. There is an exception: breakdown can also be established without the one-year wait where the other spouse has committed adultery or treated the applicant with physical or mental cruelty that makes continued cohabitation intolerable. Spouses are deemed to have lived apart for any period during which they lived apart, and the Act's wording also requires that at least one of them intended to live separate and apart.

So the legal test points to the way you have lived and your intention, not to a form you filed. It is still wise to write down your separation date and keep supporting records.

When court does become necessary

A divorce is granted by a court. In New Brunswick, divorce proceedings are in the Court of King's Bench, Family Division, using the Rule 72 forms. The Family Division also handles Family Law Act matters such as parenting and support.

Court may also be needed for other issues if you cannot agree. The usual situations are in the table below.

IssueHow court can be involved
DivorcePetition in the Family Division; a joint petition (Form 72B) is possible if you agree
ParentingThe Court may make a parenting order on application by a parent
Spousal supportOn a divorce proceeding the court may order lump sum or periodic support
Marital propertyAn application for division generally must be made within sixty days after the divorce
SafetyAn Emergency Intervention Order may be applied for by the victim

Agreements can avoid a court fight

If you and your spouse can agree, a written domestic contract, such as a separation agreement, must be in writing, signed by the parties to be bound, and witnessed. A valid domestic contract generally prevails over a conflicting provision of the Marital Property Act.

The witnessing rule does not itself make a lawyer mandatory, but independent legal advice matters. The Court may disregard a provision where a spouse signed without independent legal advice and applying it would be inequitable.

Once a divorce proceeding has started, the Divorce Act says the parties are to try to resolve the matters that may be the subject of an order, including through family dispute resolution processes, to the extent appropriate.

Common-law partners are treated differently

A common-law partner is a person who cohabits in a conjugal relationship with another person without being married to them. The Marital Property Act's equal-division rule applies to married spouses, so common-law partners do not get automatic equal division of the home or other property.

Unmarried partners generally rely on unjust enrichment or negotiate a settlement, and living together alone does not create an entitlement to a share. Spousal support can extend to common-law partners who cohabited continuously for at least three years with one substantially dependent on the other, or who are parents of a child and cohabited in a relationship of some permanence.

What to do next

A lawyer can confirm which steps apply to your situation and whether a court filing is worthwhile now or later.

Frequently asked questions

Can I be separated without telling a court?

For divorce purposes, the test is whether you lived separate and apart, with at least one spouse intending that. Nothing in that test turns on a court filing. Keeping your own records of the date is still sensible.

Do I need a court order for parenting arrangements?

Not necessarily. Parents can agree, and the Family Law Act says parents share parenting time and decision-making responsibility unless otherwise agreed in writing or ordered by the Court. A parenting order is available when you cannot agree.

Do I have to divorce right away?

No. The usual divorce ground is a year of separation, though breakdown can be established without that wait where the other spouse has committed adultery or treated you with cruelty that makes continued cohabitation intolerable. Be aware that a marital property application generally must be made within sixty days after the divorce, though the Court can extend that in limited cases.

What if my spouse refuses to cooperate?

A divorce can proceed on one spouse's petition even where the other does not cooperate, and the court decides after the separation is proved. If the other spouse disagrees, the Rule 72 forms provide for an Answer and other responses.
