Rent & Deposits New Brunswick published June 13, 2025 Flag of New Brunswick

If you’re a tenant in New Brunswick faced with a claim from your landlord for arrears (unpaid rent) or back rent, it’s important to understand the dispute process, your rights under provincial law, and how to take timely action. This guide walks you through when and how you can dispute arrears or back rent, links to official resources, and offers practical tips for tenants.

Understanding Arrears and Back Rent

Arrears (unpaid rent) can arise if you miss one or more rent payments or if there is a disagreement about how much rent you owe. Landlords can pursue unpaid rent or issue eviction notices if arrears aren’t resolved. However, as a tenant, you have the right to dispute these claims if you believe them to be incorrect or unfair.

Your Legal Rights as a Tenant

Tenants and landlords both have specific rights and responsibilities in any rental relationship. For a broader understanding, the page Tenant Rights and Landlord Rights in New Brunswick covers general tenant protections and obligations in the province.

How to Dispute a Claim for Arrears or Back Rent

If your landlord says you owe arrears, you don’t have to accept the claim without question. Here’s what you should know and do:

  • Ask your landlord for a detailed, written explanation or accounting of what is owed.
  • Check your lease, payment receipts, and bank records for evidence of what you have paid.
  • If you disagree with the landlord’s claim, notify them in writing ASAP, explaining your reasons.
  • If you cannot settle the matter privately, the landlord may apply to the Tribunal to seek an order for arrears or to evict you.

Responding to a Notice of Hearing or Application

If your landlord files a claim, the Residential Tenancies Tribunal will notify you, usually with a Notice of Hearing or an Application to terminate the tenancy. This is your opportunity to present your side.

  • Form 6 - Application by Landlord: This form is used by landlords to start proceedings for arrears or eviction. You will be served a copy if your landlord files it.
    Find the official Form 6 and process here.
    Example: You receive Form 6 and notice a hearing is scheduled 7 days later. You must act swiftly to gather proof and respond.
  • Form 15 - Written Response by Tenant: Use this form to respond to a landlord’s application. State your version of events and include supporting documentation (e.g., proof of payment).
    Download Form 15 from the NB Tribunal site.
    Example: Your landlord says you missed a rent payment. You attach bank statements showing payment was made on time and submit Form 15.

Attending the hearing and submitting your response on time is crucial so your case can be heard fairly.

Tips for Tenants Involved in a Dispute

  • Keep records of all rent payments (receipts, e-transfers, etc.)
  • Communicate with your landlord in writing and keep a copy of all correspondence
  • Submit all evidence to the Tribunal by the deadlines provided
