Handling Security Deposit Disputes When a Co-Tenant Vacates

Rent & Deposits Prince Edward Island 6 min read · published November 11, 2026 Flag of Prince Edward Island

When a co-tenant vacates a rental home in Prince Edward Island, questions about the security deposit can quickly become stressful. The departing renter may want their share immediately, while the remaining tenant or landlord may believe the deposit must stay in place until the tenancy ends. Your rights can depend on the lease, the names on it, the reason for leaving, and whether damage or unpaid rent is alleged. This guide explains practical steps for tenants, including how to document the agreement, communicate with the landlord, protect the deposit, and use Prince Edward Island's residential tenancy process if a dispute cannot be resolved.

A written agreement between co-tenants can prevent confusion about who paid the deposit and who will receive it.

How security deposits work in Prince Edward Island

A security deposit is money held to protect a landlord against permitted losses, such as unpaid rent or damage beyond ordinary wear and tear. It is not automatically a payment for the final month's rent. The lease and the Residential Tenancy Act are important starting points for understanding the parties' obligations.[1] For general background, see Understanding Rental Deposits: What Tenants Need to Know.

In a joint tenancy, the landlord may treat the named tenants as jointly responsible under the rental agreement. A co-tenant who moves out does not necessarily end the whole tenancy or create an automatic right to receive a proportional deposit refund. The landlord, remaining tenant, and departing tenant should confirm in writing whether the departing tenant is being replaced, released, or simply leaving while the agreement continues.

The lease, payment records, and written communications can be more useful than assumptions about each tenant's share.

What happens when one co-tenant leaves

Check the rental agreement first

Look for clauses about ending a tenancy, assignment, subletting, replacement tenants, notice, and the return of a security deposit. Identify every person named as a tenant and determine whether the landlord has agreed to remove the departing person from the agreement. If the lease is silent, ask the landlord for a written decision before keys are returned.

Separate the landlord's claim from the co-tenants' private agreement

Co-tenants can agree that one person will reimburse another for part of the deposit. That private payment does not necessarily bind the landlord or determine whether the landlord may make a lawful deduction at the end of the tenancy. The remaining tenant may ask the departing tenant to document the transfer, while the departing tenant should avoid describing the payment as a final release unless the parties clearly intend that result.

  • Record the amount each tenant paid, the date of payment, and any agreed reimbursement.
  • Keep the lease, receipts, inspection records, photographs, and messages about the deposit.
  • Ask for written confirmation if the landlord approves a replacement tenant or removes a co-tenant.
A clear written record can show whether a disagreement concerns the landlord's deduction or only the co-tenants' share of the money.

Common security deposit disputes

Disputes often arise when a landlord proposes deducting cleaning, repairs, unpaid rent, or other amounts after one tenant leaves. Ask for an itemized explanation and supporting documents. Ordinary wear and tear is different from damage caused by a tenant, and a tenant should not accept an unexplained deduction simply because another co-tenant has vacated.

Another common issue is a landlord's refusal to return any portion of the deposit before the entire tenancy ends. Whether an early payment is required can depend on the tenancy agreement and the applicable rules. If the landlord will not release a departing tenant, the co-tenants can negotiate a reimbursement while reserving their positions about any later claim.

Tenants should also avoid treating a security deposit as rent without written agreement or legal authority. If rent is unpaid, a landlord may have separate remedies, and using the deposit unilaterally can create additional risk.

Do not sign a release or admit responsibility for damage before reading the proposed deduction carefully.

Steps to protect your position

Act promptly and keep communications calm and specific. A departing tenant should provide the move-out date, forwarding address, key-return details, and proposed arrangement for the deposit. The remaining tenant should request a copy of any agreement that changes the named tenants or assigns responsibility for damage.

  • Confirm the date the co-tenant will vacate and whether the tenancy will continue.
  • Arrange a documented inspection and record the condition of shared areas and the departing tenant's room.
  • Take dated photographs and keep receipts for cleaning or repairs that you paid for.
  • Ask the landlord and co-tenants in writing how the deposit will be handled.
  • File an application with the Residential Tenancy Office if negotiation does not resolve the dispute.

When to contact the Residential Tenancy Office

Prince Edward Island's Residential Tenancy Office handles residential tenancy disputes through the Director's process. Contact the office when you cannot resolve a disagreement about a deposit, responsibility for damage, a change to the tenancy, or money claimed after a co-tenant leaves. The office can explain the available process and the evidence needed, but it cannot give personalized legal advice.

Use the official Residential Tenancy Office information and forms page to confirm current filing instructions, fees, service requirements, and hearing procedures.[2] The relevant application is generally called the Application to the Director; use the current version provided by the office to ask for an order about the disputed deposit or related tenancy issue. For example, a departing tenant could use it after requesting an accounting and receiving no response, attaching the lease, payment proof, inspection material, and written communications.

FAQ

Can a co-tenant automatically get their share of the security deposit when they move out?
No. An automatic partial refund is not guaranteed because the lease, the landlord's agreement, the status of the tenancy, and any possible deductions all matter.
Can the remaining tenant reimburse the departing tenant?
Yes, co-tenants can make a private reimbursement agreement, but they should record it in writing and understand that it may not release either tenant from obligations to the landlord.
What evidence should a tenant keep?
Keep the lease, deposit receipts, bank records, photographs, inspection reports, repair invoices, key-return proof, and messages about the move-out and proposed deductions.
Where can a Prince Edward Island tenant bring a deposit dispute?
A tenant can contact the Residential Tenancy Office and review the current Application to the Director process for a dispute that cannot be resolved directly.

How-To

  1. Confirm the co-tenant's move-out date and the tenancy's status.
  2. Review the lease and identify who is responsible for the security deposit.
  3. Document the home's condition, payments, keys, and communications.
  4. Ask the landlord and co-tenants for a written deposit decision.
  5. Submit the current Application to the Director if the dispute remains unresolved.

Moving out and preserving evidence

Before leaving, review Moving Out Tips: A Tenant's Guide to a Smooth Rental Exit and follow the lease's notice and key-return requirements. Give the landlord a reliable forwarding address and keep proof that the notice and keys were delivered. If a final inspection is offered, attend when possible and record what was discussed. Do not discard messages or photographs after receiving a refund because a later dispute may still concern the amount, timing, or responsibility for a deduction.

A dated photo of a clean room and a written key-return confirmation can help distinguish pre-existing conditions from later allegations.

Key Takeaways

  • A co-tenant's departure does not automatically require an immediate proportional deposit refund.
  • Written agreements and condition records help separate legitimate deductions from unsupported claims.
  • Use the current Prince Edward Island Application to the Director when direct negotiation fails.
