Here is a question to the blog clinic from Simon who is a landlord
Joint tenancy due for renewal but one tenant is too ill to attend. Can one tenant sign on the others behalf with a letter of authority?
Strictly speaking, only if they have power of attorney, which I doubt they do.
My advice would be either to wait until the tenant is well enough to attend, or arrange to have the tenant sign the form at home.
If you allow the other tenant to sign on their behalf, this may not be considered sufficient to bind the ill tenant – for example if you need to sue them for unpaid rent.
In which case, probably either
- the tenant who signed will have become the sole tenant and the other occupiers will be lodgers or
- the renewal form will not take effect
If you decide to wait and the fixed term ends before the ill tenant is able to sign, this is not a big problem, as the tenancy will just continue as a periodic tenancy until the replacement form is signed and takes effect.
