Splitting Rent and Deposits With Roommates in New Brunswick

Rent & Deposits New Brunswick published June 25, 2025 Flag of New Brunswick

Living with roommates in New Brunswick can make renting more affordable, but it comes with important responsibilities—especially when it comes to splitting rent and deposits. Understanding your rights and obligations will help you avoid disputes and ensure a smooth tenancy.

How Rental Agreements Work With Roommates in New Brunswick

In New Brunswick, rental laws apply equally to shared rentals, but the way you and your roommates sign your lease has practical consequences:

  • Each tenant's name should be on the lease (the Standard Form of Lease), making each person equally responsible for rent and damages.
  • If only one roommate signs, that person is legally responsible for the whole rent and security deposit.
Consider a written roommate agreement outlining how you'll split rent, deposits, utilities, and other responsibilities. While not enforceable under provincial law, it can help prevent misunderstandings.

In New Brunswick, the official authority for residential tenancies is the Residential Tenancies Tribunal. Tenancy rules are governed by the Residential Tenancies Act (New Brunswick)[1].

Splitting Rent With Roommates: Your Rights and Practical Steps

Splitting rent can seem straightforward, but it’s important to know how New Brunswick law treats your agreement:

  • All tenants named on the lease are jointly and severally liable. If one roommate fails to pay, the landlord can require the others to cover the shortfall.
  • The lease should specify the total rent, but doesn’t require the landlord to recognize individual shares. You and your roommates must agree on each person's portion.
  • Rent is usually collected as one payment per month. Decide who will send the payment to the landlord and keep clear records.

Understanding Deposits in Shared Rentals

In New Brunswick, landlords can collect a security deposit that is no more than one month's rent. This deposit is held in trust by the landlord and regulated under provincial law.

  • The security deposit is for the whole unit, not per individual. Roommates usually combine their shares to make the payment.
  • On move out, the landlord returns the deposit (plus interest) to the group—not individuals. Roommates are responsible for dividing it based on any prior arrangement.
  • If one roommate causes damage, the landlord may deduct from the deposit, affecting everyone’s share.

Move-In and Move-Out Forms: Protect Your Share

Before moving in, it's important to complete a condition inspection with your landlord. This helps avoid disputes about damages when moving out.

  • Condition Report (Form 1): Used by tenants and landlords to note the condition of the unit at move-in and move-out. Access the Condition Report (Form 1). Each roommate should sign, if named on the lease.

At the end of your tenancy, you may file a Security Deposit Claim (Form 3) if you believe the landlord has unfairly withheld your deposit. Access Security Deposit Claim (Form 3) and submit it to the Residential Tenancies Tribunal. Use this if there is a dispute about how the deposit should be returned among roommates.

What Happens When a Roommate Moves Out?

Roommate changes can complicate shared arrangements:

  • Unless the landlord agrees to update the lease, original tenants remain liable until the lease officially ends.
  • If a roommate wants to leave, try to reach a written agreement with all roommates on how to handle their share of the deposit and any rent owing.
  • Notify your landlord in writing and complete a new lease if someone is to be removed or added. Use a new Standard Form of Lease for updates.

Common Challenges: Disagreements, Damages, and Payments

Roommates disputes are unfortunately common when it comes to sharing expenses or damages. To resolve issues:

  • Keep written records of all payments and communications.
  • Use a fair process for splitting the deposit upon move out (consider prorating according to each person's stay if not all tenants leave together).
  • Contact the Residential Tenancies Tribunal if disputes cannot be resolved within the group.
