How to Claim Security Deposit Interest in New Brunswick

Rent & Deposits New Brunswick 5 min read · published September 14, 2026 Flag of New Brunswick

If you are a renter in New Brunswick, your security deposit is not simply money a landlord can keep without explanation. When your tenancy ends, you may be entitled to have the deposit returned with applicable interest, subject to lawful deductions and the province's residential tenancy rules. This guide explains how to check your deposit records, request payment, respond to a proposed deduction, and apply to the Residential Tenancies Tribunal if necessary. Whether you are moving out of an apartment or resolving an old deposit dispute, these practical steps can help you protect your tenant rights and present a clear claim.

How security deposit interest works in New Brunswick

New Brunswick's Residential Tenancies Act governs security deposits and the responsibilities of landlords and tenants. A landlord generally must handle the deposit through the process required by the Director of Residential Tenancies, rather than treating it as ordinary rental income. Interest is calculated according to the applicable provincial rules and rate, so the amount may vary by the period in which the deposit was held.[1]

Review Understanding Rental Deposits: What Tenants Need to Know for general information about deposit limits, receipts, and common rental practices. Your lease, deposit receipt, payment records, and move-out documents can help establish the amount paid and the date it was collected.

The interest amount depends on the applicable New Brunswick rate and the period for which the deposit was held.

When can a tenant claim the deposit and interest?

You can ask for the deposit and applicable interest after the tenancy ends and you have returned possession of the rental unit. A landlord may be entitled to claim certain amounts for unpaid rent or damage beyond ordinary wear and tear, but deductions should be supported by the tenancy agreement, inspection evidence, invoices, receipts, or other reliable records.

  • Confirm the original deposit amount and any interest or deduction information provided by the landlord.
  • Record the date you moved out, returned the keys, and gave the landlord your forwarding address.
  • Keep photographs, inspection reports, rent receipts, messages, and invoices connected with the condition of the unit.
  • Send a written request that identifies the rental address, deposit amount, tenancy dates, forwarding address, and payment deadline.
Keep a copy of every request and attachment you send to the landlord.

How to request payment from your landlord

Start with a clear written request instead of relying only on a phone call. State that the tenancy has ended, ask for the return of the security deposit and applicable interest, and request an itemized explanation for any proposed deduction. Give a reasonable date for payment and provide a reliable mailing address or payment method.

If the landlord says there was damage, compare the claim with your move-in and move-out records. Ordinary wear from normal use is different from damage caused by a tenant, and a disagreement about responsibility does not automatically decide the issue.

What to do if the landlord does not pay

If the landlord does not respond or refuses to pay, organize your evidence and contact New Brunswick's Residential Tenancies Tribunal for the current dispute-resolution process. The official process may require an application, supporting documents, service or delivery of materials, and participation in a hearing or other proceeding. Follow the current instructions carefully because forms, filing methods, and deadlines can change.

Evidence that can support your claim

  • The signed lease, security deposit receipt, rent ledger, and proof of the original payment.
  • Move-in and move-out inspection reports, dated photographs, videos, and written descriptions of the unit.
  • Emails, text messages, letters, and notes showing your request for the deposit and the landlord's response.
  • Invoices, receipts, statements, or calculations that help establish the amount claimed or disputed.
A simple timeline can make it easier to explain when the tenancy ended and when each request was made.

Official application and forms

Use the current tenant application or dispute form published by New Brunswick's Residential Tenancies Tribunal or Service New Brunswick. The official forms page identifies the current form name and any assigned number; use the tenant application for a dispute when a landlord has not returned the deposit or has made an unsupported deduction. For example, a tenant who moved out on June 30 and received neither the deposit nor an accounting can attach the lease, payment proof, photographs, forwarding address, and written demand to the application.

Do not rely on an old copy downloaded from another website. Check the official instructions for how to file, how to deliver documents to the other party, and whether a hearing date or additional evidence is required.
