How to get an annulment of marriage in Manitoba.

1 Jul 2026 5 min read No comments Divorce & Separation Guides Manitoba

An annulment in Manitoba is exceptionally rare and is only granted if your marriage was legally invalid from the very beginning. Common reasons include bigamy, extreme intoxication at the ceremony, or marrying a close relative. A short marriage duration is never a valid ground for an annulment.

When people realize they have made a terrible mistake shortly after saying “I do,” their first instinct is often to seek an annulment. Whether the wedding took place in a grand Winnipeg hotel or a small church in Morden, many believe that a marriage lasting only a few weeks can simply be erased. However, Canadian law is very strict. An annulment (formally called a Declaration of Nullity) does not end a valid marriage; it declares that a valid marriage never legally existed in the first place. This guide outlines the specific, narrow grounds for an annulment in Manitoba, the steps to apply, and why a standard divorce is usually the necessary route.

Step-by-Step Process for an Annulment in Manitoba

Obtaining an annulment involves proving to the Court of King’s Bench that your marriage suffers from a fatal legal defect. Marriages are classified as either “void ab initio” (invalid from the start, such as bigamy) or “voidable” (valid until challenged, such as inability to consummate). Here is how the process generally unfolds.

Step 1: Determine if You Have Legal Grounds

You must fit into a very specific legal category. 🔍 You might qualify if one spouse was already legally married to someone else (bigamy), if you are too closely related by blood or adoption (consanguinity), if one party lacked the mental capacity to understand the ceremony (due to severe intoxication or mental illness), or if the marriage was entered into under severe physical duress. Additionally, an inability (not just a refusal) to physically consummate the marriage due to a medical condition unknown at the time of the wedding can be a valid ground.

Step 2: Gather Conclusive Evidence

Because courts are reluctant to invalidate marriages, your evidence must be overwhelming. If claiming bigamy, you need the prior marriage certificates. If claiming extreme intoxication or lack of capacity, you will need medical records or credible witness affidavits proving you literally did not understand you were getting married. If claiming fraud, the fraud must go to the very core of the marriage ceremony itself, not just lies about a spouse’s wealth or past.

Step 3: File a Petition (Form 70B)

If you have the grounds, your lawyer will draft a standard Petition (Form 70B) specifying a request for a declaration of nullity. Under Manitoba Court of King’s Bench Rule 70.03(2), an annulment claim (which is governed by the Divorce and Matrimonial Causes Act, 1857) must be filed using a standard Petition (Form 70B), as the Petition for Divorce (Form 70A) is reserved solely for actions under the federal Divorce Act. This is filed at the Court of King’s Bench. You must then formally serve this Petition on your spouse, who has the right to file an Answer and contest the annulment.

Step 4: Attend a Court Hearing

Unlike simple uncontested divorces that can often be handled via paperwork, an annulment almost always requires you to appear before a judge. You or your legal counsel must present your evidence and convince the court that the strict legal test for nullity has been met.

How Much Does it Cost in Manitoba?

Applying for an annulment can actually be more expensive than a standard divorce due to the complexity of the legal arguments and the heavy burden of proof required.

  • Court Filing Fees: The filing fee to start your family proceeding at the Court of King’s Bench is exactly $200 CAD.
  • Evidence Gathering: Hiring private investigators (to prove bigamy) or obtaining specialized medical reports can add hundreds or thousands of dollars to your costs.
  • Lawyer Fees: Because annulment cases are rare and highly technical, legal representation is strongly advised. Expect to pay between $3,500 and $7,500+ CAD depending on whether your spouse contests the application.
Ground for AnnulmentType of InvalidityExamples
BigamyVoid from the startSpouse never finalized their previous divorce
Lack of CapacityVoid from the startBlackout drunk during a Vegas or destination wedding
Non-ConsummationVoidableUnknown physical/psychological inability to have intercourse
DuressVoidableA “shotgun wedding” forced by threats to your life

How Long Does the Process Take?

If you can clearly prove a blatant defect like bigamy, the court might grant the Declaration of Nullity within 4 to 6 months. However, if the matter is highly contested (for instance, arguing over mental capacity or duress), scheduling a full trial at the Court of King’s Bench could easily take 12 to 18 months. Ironically, the 1-year waiting period for a standard divorce is often faster than fighting a contested annulment.

Frequently Asked Questions (FAQ)

Can I get an annulment just because we were only married for a month?

No. Under Canadian law, the length of the marriage is completely irrelevant. Even if you want out the morning after the wedding, if the ceremony was legally valid and you both consented, you must get a divorce.

My spouse lied about their finances; is that grounds for annulment?

Generally, no. Lying about wealth, career, or past relationships does not invalidate the marriage ceremony itself. Fraud must involve tricking someone into the actual ceremony (e.g., you thought it was a costume party, not a real wedding).

What happens to property division if an annulment is granted?

Even if an annulment is granted, the courts in Manitoba still have the power to make orders regarding child support, parenting time, and in some cases, the division of property acquired during the relationship under family property laws. However, under section 19(2) of Manitoba’s Family Property Act, you must file any claim for an accounting and equalization of family assets within a strict 60-day limitation window starting from the day any appeal against the decree of nullity is finalized or after the time to appeal has expired. Missing this 60-day window permanently extinguishes your property division rights.

Is a religious annulment the same as a legal one?

No. A religious annulment (such as one granted by the Catholic Church) only affects your standing within that faith. It has no legal effect in Manitoba. You still remain legally married in the eyes of the government until a court issues a divorce or legal annulment.
