Key Facts: Changing Locks During Divorce in New Brunswick

Understanding Matrimonial Home Rights in New Brunswick

Both spouses in New Brunswick have equal rights to possess and occupy the marital home during separation and divorce proceedings, regardless of property ownership. Under section 2 of the Marital Property Act, RSNB 2012, c. 107, child care, household management, and financial provision are recognized as joint responsibilities of equal importance, and each spouse is entitled to an equal share of marital property. This equal entitlement extends to possession rights, meaning you cannot legally force your spouse to leave by change locks marital home without court authorization.

The Marital Property Act defines a marital home as property in which one or both spouses have an interest and that is or has been occupied as their family residence. If the property serves multiple purposes beyond family residence, only the portion reasonably necessary for family use qualifies as the marital home. This definition applies whether the home is owned, rented, or held under any other arrangement.

New Brunswick courts take possession rights seriously because the matrimonial home often represents the family's largest asset and provides stability for any children. According to Family Law NB, both spouses maintain their equal right to remain in the matrimonial home and use household items until a court order or separation agreement provides otherwise. Attempting to circumvent these rights by locking doors during divorce can backfire, damaging your position in property division negotiations and parenting arrangement disputes.

Legal Consequences of Changing Locks Without Authorization

Changing the locks on your marital home without a court order or your spouse's agreement exposes you to multiple legal consequences under New Brunswick law. The Court of King's Bench, Family Division has authority to order you to restore your spouse's access immediately, award costs against you, and consider your unilateral action when dividing property or determining parenting arrangements. Courts view spouse locked out house situations as evidence of bad faith that undermines cooperative resolution.

Under section 11 of the Marital Property Act, the Court may make interim orders as it considers necessary for restraining the disposition or impoverishment of any property and for the possession, safekeeping, and preservation of property that may be divided. A locked-out spouse can apply for such an order on short notice, and judges routinely grant immediate relief when one party has been wrongfully excluded from the family home.

In extreme cases, locking out your spouse could potentially lead to criminal liability. Section 349 of the Criminal Code of Canada addresses being unlawfully in a dwelling-house, and while this typically applies to strangers, domestic situations involving property disputes can escalate into criminal matters, particularly if physical confrontations occur when the locked-out spouse attempts to regain entry.

How to Legally Obtain Exclusive Possession in New Brunswick

New Brunswick provides two primary legal mechanisms for obtaining exclusive possession of the marital home: an order under the Marital Property Act for general family law situations, and an Emergency Intervention Order under the Intimate Partner Violence Intervention Act for domestic violence circumstances. Each mechanism has distinct requirements, timelines, and effects.

Exclusive Possession Under the Marital Property Act

Section 23 of the Marital Property Act authorizes the Court to direct that one spouse be given exclusive possession of a marital home or part of it for any period the Court directs. This application requires filing with the Court of King's Bench, Family Division, paying the $110 filing fee, and demonstrating grounds that justify granting exclusive possession. The Court considers factors including the best interests of any children, each spouse's financial circumstances, the availability of alternative housing, and any history of family violence.

The spouse granted exclusive possession may be ordered to pay periodic payments to the other spouse for use of the marital home, reflecting the excluded spouse's continuing ownership interest. The Court may also allocate responsibility for repairs, maintenance, mortgage payments, and other liabilities arising from the property. These orders can be made as temporary relief pending final property division under section 23(2).

Typical processing time for an exclusive possession application ranges from 2 to 8 weeks depending on whether the application is contested. Urgent applications can be heard on shorter notice, but you must demonstrate genuine urgency to the Court. Your application should include detailed evidence supporting your request, such as affidavits describing why exclusive possession is necessary and how it serves the interests of any children.

Emergency Intervention Orders for Domestic Violence

The Intimate Partner Violence Intervention Act, SNB 2017, c. 5 provides a faster mechanism for obtaining exclusive occupation of the family residence when intimate partner violence has occurred or is likely to occur. Emergency Intervention Orders can include provisions for exclusive occupation of the residence, removal of firearms, no-contact requirements, temporary care of children, and supervised property removal.

To obtain an Emergency Intervention Order, you must contact a designated Service Provider or Assister who will help you complete the application forms and submit them to a Hearing Officer. The Hearing Officer must schedule a telephone hearing within 24 hours, with hearings available between 8:30 AM and 4:30 PM, 7 days per week. The speed of this process reflects the legislature's recognition that domestic violence situations require immediate intervention.

The Intimate Partner Violence Act defines violence broadly to include abusive, threatening, harassing, or violent behaviour; withholding food, clothing, and medical attention; and restricting shelter, transportation, and other necessities of life as a way to psychologically, physically, sexually, or financially coerce, dominate, and control a partner. If your situation involves any of these behaviors, the Emergency Intervention Order route may be more appropriate than a standard exclusive possession application.

Step-by-Step Process for Exclusive Possession Applications

Obtaining exclusive possession of the marital home in New Brunswick requires careful preparation and adherence to court procedures. The following steps outline the standard process for applications under the Marital Property Act, with total costs typically ranging from $110 to $500 depending on complexity and whether you use legal representation.

First, gather documentation supporting your application, including property ownership records, evidence of mortgage or rent payments, photographs of the home, and any records of incidents that support your need for exclusive possession. If children reside in the home, prepare evidence showing how exclusive possession serves their best interests, such as proximity to schools, medical providers, and support networks.

Second, obtain the required court forms from the Court of King's Bench, Family Division. The primary forms include Form 72A (Petition for Divorce) if you are also seeking divorce, and additional motion forms specific to your exclusive possession request. PLEIS-NB publishes the handbook "Doing Your Own Divorce in New Brunswick" available at provincial libraries or for $10 from PLEIS-NB at (506) 453-5369.

Third, file your application with the Registrar of the Court of King's Bench, Family Division in the judicial district where you or your spouse resides, or where your children ordinarily reside if parenting matters are at issue. Pay the $110 filing fee ($100 petition fee plus $10 Clearance Certificate fee). Fee waivers are available under Form 72FF for parties receiving social assistance under the Family Income Security Act or those represented by domestic Legal Aid.

Fourth, arrange for service of your application on your spouse according to the Rules of Court. Your spouse will have an opportunity to respond, and the Court will schedule a hearing. Prepare your evidence and arguments, focusing on the factors courts consider when granting exclusive possession.

Factors Courts Consider for Exclusive Possession Orders

New Brunswick courts exercise discretion when deciding exclusive possession applications, weighing multiple factors to reach a decision that balances the interests of both spouses and any children. Understanding these factors helps you present a stronger application and anticipate potential weaknesses in your case.

The best interests of any children typically carry the most weight in exclusive possession decisions. Courts prefer to minimize disruption to children's lives, including their schools, friendships, medical care, and daily routines. If you can demonstrate that exclusive possession serves your children's stability and well-being, your application gains significant strength.

Evidence of family violence dramatically affects exclusive possession outcomes. Courts take domestic abuse seriously and will often grant exclusive possession to protect victims and children from ongoing harm. Document any incidents thoroughly, including police reports, medical records, photographs of injuries, and statements from witnesses who observed abusive behavior or its effects.

Financial circumstances matter because the Court must ensure both parties can maintain reasonable housing. If granting you exclusive possession would leave your spouse homeless with no realistic housing alternatives, courts may fashion alternative arrangements such as temporary occupancy schedules or orders requiring one spouse to contribute toward the other's housing costs.

What to Do If Your Spouse Changes the Locks

If you arrive home to find your spouse has changed the locks without a court order or your agreement, you have several legal options to restore your possession rights. Acting quickly and documenting everything strengthens your position while avoiding actions that could escalate the situation or expose you to legal liability.

Immediately document the lock change by photographing the new locks, saving any text messages or communications from your spouse about the exclusion, and noting the date and time you discovered the change. Contact the police non-emergency line to report the situation and request that an officer attend to keep the peace if you need to retrieve essential belongings. Police cannot force your spouse to let you back in without a court order, but their presence documents the dispute and may facilitate temporary access.

File an urgent motion with the Court of King's Bench, Family Division seeking interim relief under section 11 of the Marital Property Act. This motion should request that the Court order your spouse to provide you access to the marital home and restore the original locks or provide you with keys. Courts typically hear urgent family matters within days, not weeks, when genuine urgency is demonstrated.

Do not attempt to force entry, break windows, or damage property to regain access. Such actions could result in criminal charges against you and would severely damage your credibility in family court proceedings. Similarly, avoid confrontational communications with your spouse that could be characterized as threats or harassment. Maintain calm, professional communication focused on resolving the situation through legal channels.

Special Considerations: Rental Properties and Common-Law Relationships

The rules for changing locks during divorce differ somewhat for rental properties and common-law relationships in New Brunswick. Understanding these distinctions helps you navigate your specific situation appropriately and avoid legal missteps.

For rental properties, both spouses named on the lease retain equal tenancy rights regardless of marital status. Even if only one spouse signed the lease, the other spouse may have acquired tenancy rights through the Residential Tenancies Act if they have been living in the property as their primary residence. Changing locks on a rental property typically requires the landlord's involvement, as most leases prohibit tenants from changing locks without permission. If you obtain an exclusive possession order, show it to your landlord and request that they change the locks; most landlords will comply to avoid legal complications.

Common-law partners face a more complex situation under New Brunswick law. The Family Law Act, SNB 2020, c. 23 extends certain protections to common-law partners who have lived together in a marriage-like relationship for at least 3 continuous years or who have a child together and have lived together for at least 1 year. However, the Marital Property Act applies specifically to married spouses, meaning common-law partners must rely on different legal frameworks for property disputes.

Common-law partners who do not meet the Family Law Act thresholds may need to pursue remedies through general property law, such as unjust enrichment claims or resulting trust arguments. If you are in a common-law relationship and facing a lock-out situation, consult with a family law attorney to understand your specific rights and options.

Timeline: From Lock Change to Resolution

Understanding typical timelines helps you plan your response to a lock-out situation or your application for exclusive possession. The following timeline reflects general experience in New Brunswick courts, though actual timing varies based on court availability, case complexity, and whether matters are contested.

Emergency Intervention Orders under the Intimate Partner Violence Intervention Act follow a faster timeline. Application assistance is available immediately through designated Service Providers, telephone hearings occur within 24 hours, and orders can be issued the same day. This accelerated process reflects the urgent nature of domestic violence situations.

For standard exclusive possession applications without urgent circumstances, expect the process to take 4 to 12 weeks from filing to resolution. Contested applications take longer because both parties must have opportunities to file evidence and make arguments. Settlement negotiations can occur at any point and often result in faster resolution than proceeding to a contested hearing.

Protecting Yourself and Your Interests During Separation

Beyond the immediate question of changing locks divorce New Brunswick couples should take broader steps to protect their interests during separation. These protective measures reduce conflict, preserve assets, and position you for favorable outcomes in divorce proceedings.

Open a bank account in your name only and ensure you have access to sufficient funds for living expenses and legal fees. Do not drain joint accounts, as courts view such actions unfavorably, but ensure you have reasonable access to marital funds. Document all marital assets and debts by gathering financial statements, tax returns, property records, and retirement account information.

If you have children, maintain your involvement in their daily lives and avoid any actions that could be characterized as limiting their relationship with their other parent. Courts prioritize parenting arrangements that support children's relationships with both parents, and parent who attempts to alienate children or restrict the other parent's access typically faces negative consequences in parenting proceedings.

Consider whether a separation agreement might resolve lock-out concerns without court intervention. A properly drafted separation agreement can address who will occupy the family home, how household expenses will be divided, and when the home will be sold or transferred. Such agreements must be in writing, signed by both parties, and ideally reviewed by independent legal counsel for each party to be enforceable.
