I know my question doesn't affect the tenancy agreement or the guarantor situation, I was just curious as I acted as guarantor for my son on a six month assured short hold tenancy with no mention of this being extended, after eighteen months he faulted on the payments, I was then taken to court for this but the judge awarded in my favour as in the agreement there was no mention of the tenancy being extended, but he did tell the agency that they should reword their tenancy agreements.
