Many warranty contracts are permanent and relate to liability “within the framework of this lease”. This means that beyond the fixed period, liability may extend to a possible extension as well as to certain modifications, such as an increase in rents. Homeowners will usually want a guarantor living in the UK, as it is easier for them to take legal action against a UK resident if they have to. If the tenant fails to comply with their obligations under the agreement, the guarantor will pay all losses, damages, expenses and expenses caused by the tenant`s loss Your landlord may want to check whether your guarantor is able to pay the rent in the same way they verified your ability to pay. For example, by carrying out a credit check. BTW I have the possibility for G`tor to sign (under their name and address) on the AST. This shows that they had the sight and that they had the opportunity to understand the AST agreement they are guaranteeing. It is best to carefully review the warranty agreement and ask questions of the owner or agent if something is unclear. Once the contract is signed, the guarantor is bound by its general conditions. There is a “warranty-friendly” warranty document that attempts to limit the surety`s liability if the person guaranteeing it is not responsible for the loss. .
