Short answer is no.

However consider the following:

• All owners must agree to the property being rented.
• Provided the tenancy is for a term not exceeding three years any one of the owners can sign on behalf of the others. For a term exceeding three years all  owners must sign.
• Ideally tenancy agreements should name and be signed by all the legal estate owners as all dealings should involve them all. Omitting owners can cause problems later.

Are all joint owners named on your tenancy agreement?
