Being a renter in New Brunswick often means understanding how guarantors and security deposits protect landlords while affecting tenants rights. This guide explains what a guarantor does, how security deposits are collected and held, the timelines for refunds, and common reasons a landlord may legally keep part of a deposit. Youll also find practical steps to document the property condition, request return of your deposit, and apply to the Residential Tenancies Tribunal if needed. Simple examples and required forms are listed so you can act clearly and confidently when moving in or leaving a rental home in New Brunswick.

How guarantors work

A guarantor promises the landlord they will cover unpaid rent or damages if the tenant cannot pay. Guarantor agreements are legally binding written promises; they usually require a signature and clear terms about what the guarantor is responsible for. Before agreeing, guarantors should review the rental agreement, know the length of responsibility, and ask whether the guarantors obligation ends if a lease is renewed or replaced.

Ask the landlord for a copy of any guarantor agreement before signing.

Security deposit rules in New Brunswick

Security deposits are money held by the landlord to cover unpaid rent, deliberate damage, or other breaches of the lease. Tenants should get a written receipt when they pay a deposit and confirm how the deposit will be held and returned. Common reasons a landlord may keep part of a deposit include unpaid rent and damage beyond normal wear and tear; normal cleaning required for everyday use is usually not a valid reason to withhold the entire deposit. For final decisions, the Residential Tenancies Tribunal handles disputes.[1]

Document the units condition with photos on move in and move out to avoid disputes.

What to check when you pay a deposit

  • Confirm the exact amount and get a dated receipt for the deposit.
  • Ask how the deposit will be held and whether it accrues interest under provincial rules.
  • Request written terms showing when deductions are permitted and how the final accounting will be delivered.

Keeping records and preparing for disputes

Good documentation makes deposit disputes faster to resolve. Keep a file with the lease, payment receipts, dated photos or video of the unit, messages or emails with the landlord, and any repair requests. If the landlord withholds part of your deposit, ask for an itemized list of deductions in writing and keep that as evidence.

Detailed documentation increases your chances of success in disputes.
