Co-Signer vs Guarantor in PEI Rental Agreements

Leases & Agreements Prince Edward Island 4 min read · published June 24, 2026 Flag of Prince Edward Island
Renters in Prince Edward Island often face questions about who guarantees a lease. This guide explains, in plain language, the difference between a co-signer and a guarantor, when each might be requested, and what tenant and co-signer responsibilities usually include. You’ll learn how liability works, what landlords can reasonably require under PEI tenancy rules, and practical steps tenants can take when asked to add a co-signer or guarantor to a rental agreement. The goal is to help tenants make informed choices, protect credit and rights, and find practical next steps for disputes, deposits, or ending a tenancy in PEI. Read on for forms, timelines, and where to get official help.

What is a co-signer vs a guarantor?

A co-signer signs the same rental agreement as the tenant and is usually jointly responsible for rent and damages. A guarantor promises to pay or perform if the tenant fails to do so but may sign a separate guaranty document rather than the lease itself. Both roles increase a landlord’s assurance of payment, but the exact legal effect depends on the documents you sign and the wording used under PEI tenancy rules[1].

A co-signer is typically party to the lease; a guarantor often signs a separate guarantee.

When landlords may ask for one

Landlords commonly ask for a co-signer or guarantor when an applicant has limited credit, short rental history, or reduced income. They may also request extra assurances for higher-risk applications like students or recent immigrants. Before signing anything, ask the landlord to explain why the extra guarantee is needed and what it covers.

  • Rent responsibility: covers unpaid rent and recurring payments if the tenant defaults.
  • Credit or rental history: used when the tenant has limited or poor references.
  • Security deposit concerns: a landlord may seek extra assurance when refunds or deductions are at risk; see Understanding Rental Deposits: What Tenants Need to Know for deposit basics.
Ask for written details about any guarantee before you sign to avoid surprise obligations.

Key differences that matter to tenants

The practical differences usually come down to the document signed and scope of liability. A co-signer on the lease generally has equal obligations and can be pursued directly for unpaid rent. A guarantor’s liability depends on the guaranty terms and may be limited by duration or dollar amount. Always read the exact language: words like "jointly and severally" expand liability.

  • Document type: lease vs. separate guaranty determines how claims are pursued.
  • Scope of payments: rent, utilities, damages, and legal costs might be included.
  • Duration and limits: some guaranties end after a term or a fixed amount.

Responsibilities and practical steps for tenants and co-signers

If you are asked to co-sign or guarantee, take these practical steps so you know your rights and risks.

  1. Get a written copy of the lease and any guaranty before signing.
  2. Ask for the specific reasons and what the landlord expects the co-signer/guarantor to cover.
  3. Request limits in writing, such as a cap on total liability or an end date.
  4. Keep records of all rent payments and communications to reduce future disputes.

What to do if a dispute arises

If a landlord attempts to collect from a co-signer or guarantor, first discuss the issue directly and share payment records. If you cannot resolve it, tenants and guarantors can apply to the provincial tenancy board for resolution. The official PEI tenancy legislation and procedures explain timelines and how claims are handled[1][2].

As a practical example, a co-signer who paid unpaid rent should keep proof of payment, then ask the landlord for written confirmation and seek reimbursement from the tenant or a decision from the Board.

Forms and official steps (PEI)

Common official steps include requesting information from the landlord in writing, negotiating a change to the lease, or filing an application with the Residential Tenancy Board. When you file, use the official application form and follow the Board's filing deadlines and evidence rules[2][3].

  • Application to the Residential Tenancy Board: use this form when disputing rent, damages, or enforcement of guarantees.
  • Collect evidence: payment records, photographs, emails, and the lease itself are commonly required.
  • Meet deadlines: the Board sets filing timelines, so act promptly if you receive a notice.
File any dispute within the Board's timelines to preserve your rights.

FAQ

Can a landlord force a tenant to have a co-signer or guarantor in PEI?
No law prevents a landlord from requiring a co-signer or guarantor as a condition of renting, but the request must be reasonable and consistent with PEI tenancy rules; alternatives may be negotiated.
What does a co-signer legally have to pay?
A co-signer who signs the lease is usually jointly liable for unpaid rent, damages, and other costs spelled out in the lease; check for wording like "jointly and severally" for the exact effect.
How can I remove a co-signer or guarantor from a lease?
Removal generally requires landlord agreement and a signed amendment or new lease. If the landlord refuses, consider negotiating replacement guarantors or filing an application with the Residential Tenancy Board for guidance.

How-To

  1. Gather the lease, any guaranty, payment receipts, and communication records.
  2. Ask the landlord in writing to explain the guarantee terms and request any limits in the agreement.
  3. Negotiate alternatives like a larger deposit, co-tenancy screening, or a shorter guaranty period.
  4. If you cannot resolve the issue, complete and file the official application with the Residential Tenancy Board and attach your evidence.

Key Takeaways

  • Read any lease or guaranty carefully before signing and request written limits where possible.
  • Co-signers can be pursued for unpaid rent; guarantors' liability depends on the wording used.
  • If negotiations fail, file with the Residential Tenancy Board using the official forms and evidence.
