Co-signer and Guarantor Rights for Roommates (Alberta)

Roommates often ask how co-signers or guarantors affect their rights and responsibilities when renting in Alberta. This clear, practical explanation helps tenants and renters understand what a co-signer or guarantor legally promises, who can be held responsible for unpaid rent or damages, and how shared leases work. It covers how to document agreements between roommates, steps to remove a guarantor, and what to do if a landlord pursues the co-signer. Wherever possible, the guidance points to official forms and Alberta’s tenancy dispute body so renters can act confidently. The tone is plain and supportive, aimed at helping roommates protect themselves while maintaining positive housing arrangements.

Who is a co-signer or guarantor?

A co-signer or guarantor is someone who promises the landlord they will pay rent or cover damages if the tenant(s) named on the lease do not. In shared housing this often means one roommate or a parent signs so a landlord will approve applicants who otherwise might not qualify.

How liability works in Alberta

In Alberta a co-signer or guarantor can be held responsible under the lease if the lease or guarantee names them; the exact rights and enforcement options are governed by the provincial Residential Tenancies Act^[1] and disputes can be decided through the Residential Tenancy Dispute Resolution Service (RTDRS) or courts. Read any guarantee carefully to see whether liability is "joint and several" (each person responsible for the whole amount) or limited.

• Unpaid rent or arrears: landlords can pursue the co-signer for outstanding rent if the tenant does not pay.
• Damage beyond the security deposit: a guarantor may be asked to cover repair or cleaning costs.
• Breaking a fixed-term lease early: the guarantor could be responsible for remaining rent until a new tenant is found or the term ends.
• Legal action or hearings: a guarantor may be named in an RTDRS or court application related to the tenancy.

Documenting agreements between roommates

Written clarity reduces future disputes. A simple roommate agreement can explain who pays rent, utilities and how to divide responsibilities even when the lease names everyone or only one tenant.

• Agree who pays rent and utilities and how payments are tracked.
• Keep written records: signed roommate agreements, photos of unit condition, and receipts for repairs.
• Keep copies of the signed lease and any guarantor forms; these documents are key if you need to file a claim.

What to do after signing

If you recently signed a lease with a co-signer, review the lease and the guarantee immediately and keep originals in a safe place. For practical next steps and moving-in tips see What Tenants Need to Know After Signing the Rental Agreement.

Removing or limiting a guarantor's liability

Removing a guarantor usually requires the landlord's written consent or a new agreement that releases the guarantor. If the landlord refuses, tenants or guarantors can apply to the RTDRS to resolve disputes or request relief^[2]. In some situations negotiating a replacement tenant or a written amendment to the lease is the fastest solution.

FAQ

Can a landlord go after a co-signer if my roommate moves out?

Yes. If the co-signer signed a guarantee that covers rent or damages, the landlord may pursue them for amounts owing under the lease even if one roommate leaves.

Can a guarantor be removed from the lease?

Only with the landlord's written agreement or by an order from the RTDRS or court; a landlord does not have to agree to release a guarantor unless a new agreement is made.

Are there alternatives to asking someone to co-sign?

Yes. Options include a larger security deposit (if permitted), a shorter lease term, a letter of employment or proof of income, or using a rental platform to find other suitable units—see Find rental homes across Canada on Houseme.
