Key takeaways
  • The usual rule is one year living separate and apart immediately before the divorce is decided.
  • You can be treated as separated even while living in the same home, subject to proof.
  • Resuming cohabitation for no more than ninety days, with reconciliation as its primary purpose, does not interrupt the separation period.

Many people ask how soon they can be divorced once the relationship ends. The answer comes from the federal Divorce Act, which applies in New Brunswick as it does across Canada.

The rule is simple to state but raises practical questions: when did you actually separate, does living in the same house count, and what if you tried to patch things up? This article covers each of them.

This article covers the law of New Brunswick.

The one-year rule

A court may grant a divorce on the ground that the marriage has broken down. Breakdown is established if the spouses have lived separate and apart for at least one year immediately before the divorce proceeding is decided.

The wording matters. The year must run up to the time of the decision, not just at some point in the past. How this fits the timing of your own case depends on your situation, so it is worth confirming with a lawyer.

Ways around the wait

The one-year period is not the only route. Breakdown can also be established, without the wait, where the other spouse has committed adultery or treated the applicant with physical or mental cruelty that makes continued cohabitation intolerable.

These grounds depend on proof and on the facts, so many people still rely on the separation year. A lawyer can explain whether an exception realistically fits your situation.

How a divorce is filed in New Brunswick

Divorce proceedings in New Brunswick are in the Court of King's Bench, Family Division, using Rule 72 forms. Spouses who agree may file together using Form 72B, the Joint Petition for Divorce, rather than one spouse filing Form 72A and serving the other with a Notice of Petition (72C).

If the other spouse disagrees, the Rule 72 forms provide for an Answer (72D), Answer and Counter-Petition (72F), Notice of Intent to Defend (72I) and a Reply (72E); a Request for Divorce (72K) and Divorce Judgment (72M/72N) follow, then a Certificate of Divorce (72O).

Can you be separated under one roof?

Yes, it can be possible. Spouses are deemed to have lived separate and apart for any period during which they lived apart, and the Act's wording also requires that at least one of them had the intention to live separate and apart. So the clock can run even if you shared a home, subject to proof.

The full statutory wording should be confirmed for your case. Evidence is what usually makes the difference. Things that may help show separation include:

When does the clock start, and what if you reconcile?

The clock runs from the period during which you lived apart with at least one spouse intending to separate. That is why a clear, provable date is valuable.

Trying again does not necessarily wipe out the time already counted. The separation period is not considered interrupted or terminated if the spouses resume cohabitation for a period of not more than ninety days with reconciliation as its primary purpose. A longer period, or one with a different purpose, may be treated differently, so get advice if this has happened.

SituationHow it relates to the separation year
Living in the same homeThe clock can run, subject to proof, if at least one spouse intended to live separate and apart.
Reconciling for ninety days or less, mainly to reconcileThe separation period is not considered interrupted or terminated.
Adultery or cruelty making cohabitation intolerableBreakdown can be established without the one-year wait.

What else matters, and what to do next

Separation is not the only requirement. A court in a province can hear a divorce if either spouse has been habitually resident there for at least one year immediately before the proceeding starts. If there are children, the court must be satisfied that reasonable arrangements have been made for their support.

Your spouse does not need to agree. Nothing in the one-year ground makes the other spouse's signature or agreement a condition.

The court also has a duty to consider the possibility of reconciliation. 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.

Property is a separate question from the divorce itself. An application for division under the Marital Property Act must generally be made within sixty days after a spouse ceases to be a spouse by reason of a divorce or declaration of nullity, though the Court can extend the time where a person lacked knowledge or was prevented by circumstances beyond their control.

Frequently asked questions

Do we both have to agree to separate?

No. The one-year ground is based on living separate and apart, and the Act's wording requires that at least one spouse intended it. The other spouse's agreement is not a condition.

Does living in the same house stop the clock?

Not necessarily. Spouses can be deemed to have lived separate and apart even while in the same home, subject to proof. Evidence of how you lived matters.

Does a brief reconciliation restart the year?

Not if it is short. Resuming cohabitation for no more than ninety days with reconciliation as its primary purpose does not interrupt the separation period.

Can I divorce sooner than one year?

Possibly, if the other spouse has committed adultery or treated you with physical or mental cruelty that makes continued cohabitation intolerable. These grounds need to be proved, so get legal advice first.
