Grounds for Divorce in Nova Scotia: Separation, Adultery, and Cruelty

One Ground, Three Ways to Prove It

Under section 8 of the federal Divorce Act, there is only one legal ground for divorce in Canada: the permanent breakdown of the marriage. But the Act recognizes three distinct ways to prove that breakdown occurred. The one you choose has major practical consequences for your filing timeline, costs, and stress level.

One-Year Separation (The Standard Path)

The vast majority of divorces in Nova Scotia — and across Canada — use this ground. You and your spouse must have lived separate and apart for at least one continuous year.

Key details:

• You can file your paperwork immediately upon separating. You don't have to wait the full year to start the process. But the judge cannot sign the final Divorce Order until the 365-day mark has passed.
• Living under the same roof still counts as separation if you've genuinely ended the conjugal relationship: separate finances, no shared meals, sleeping in different spaces, presenting yourselves as single to the outside world.
• The court evaluates separation as a factual state, not a geographic one. A judge looks at whether you've actually separated your lives, not just whether you have different mailing addresses.

The 90-day reconciliation rule: A reconciliation attempt of up to 90 consecutive days does not restart the one-year clock. If you move back in together for 87 days and it doesn't work, your original separation date still holds. But if you cohabit for more than 90 days, the clock resets completely.

Adultery (The Expedited — But Risky — Path)

Filing on the ground of adultery can theoretically bypass the one-year waiting period. In practice, it almost never simplifies things.

Requirements:

• Only the other spouse's adultery counts — you can't file based on your own infidelity
• You must provide evidence: a sworn affidavit from the other spouse admitting the act, or corroborating witness testimony
• You must prove you haven't condoned (forgiven) the adultery
• If you lived together for more than 90 days after discovering the adultery, the court may consider it forgiven

Why most lawyers advise against it: Filing on fault-based grounds virtually guarantees a contested response. What could have been a 2-to-4-month paper-based desk divorce becomes a courtroom battle with formal evidence hearings and mandatory court appearances. The resulting legal fees typically dwarf whatever time you saved by skipping the separation period.

Physical or Mental Cruelty (The Hardest to Prove)

This ground requires demonstrating that your spouse treated you with cruelty so severe that continued cohabitation is intolerable. The bar is high.

Requirements:

• The cruelty must be severe and persistent — not a single incident or ordinary marital conflict
• You carry the full burden of proof
• Objective evidence is expected: medical records, police reports, third-party affidavits
• You'll need a formal evidence hearing before a judge

This path can allow a divorce before the one-year separation period. But the evidentiary requirements mean it's rarely practical without legal representation, and it often leads to a contested proceeding.

Which Ground Should You Use?

For self-represented filers, one-year separation is almost always the right choice. It's non-adversarial, processed on paper, and doesn't require proving anyone did anything wrong. The other two grounds exist as legal options, but the procedural costs of using them — both financial and emotional — usually outweigh the benefit of a faster timeline.
