Is my agreement valid if one co-owner has not signed?

(updated on Thursday, November 18th 2010)

We have moved into a property and signed a TA with the owner. Turns out he is seperated and the ex has turned up saying the TA is not relevant as she hasn't signed - being a co-owner. She hasn't lived there for several months. Does being a co-owner make her a landlord or is our agreement solely with the man we signed up with and they have to sort out the issues they have?

Our Experts Answer:

The Residential Tenancies Act 1986 (the Act) applies only to the relationship between a tenant and landlord. A tenancy agreement can still be valid where there are joint owners, and a tenancy has been entered into with one of the owners. If the co-owner was never a party to your tenancy agreement (not recorded on the tenancy agreement, or never agreed to as being a landlord), then your obligations under the Act will be to your landlord that you entered into the agreement with.

Your landlord may need to seek independent legal advice regarding any disagreement they have with the co-owner, whilst ensuring they comply with their responsibilities as a landlord under the Act. If there is any uncertainty as to whether the tenancy agreement is valid or not, either party can make an application to the Tenancy Tribunal to have the matter resolved. To discuss your situation further, or for information about applying to the Tenancy Tribunal, you can visit the Department of Building and Housing website (, or call 0800 TENANCY (0800 836 262).
