Any experience of this? X has acted as guarantor for child's rental of room. Child has problems with landlord (or agent) not sure which. Damp and rats etc. Cleaning - it is a huge shared property with multiple tenants and there is a cleaner. Cleaner leaves and child takes up this role being paid £50 a month -. The landlord stops paying this. Maintenance - this is not being done and things are getting a bit serious. The child complains and eventually complains very bitterly in writing to the landlord (or agent) about the maintenance company saying that the maintenance company are ripping the landlord off. The maintenance guy turns up and threatens child with violence. The landlord gives child notice to quit the room with around 2 months notice. The child has not being paying rent due to repairs not being done. Child has been to Citizens Advice and on their advice has begun proceeding via a solicitor re repairs and is in process of securing Legal Aid before taking landlord to court. The landlord then contacts X with a bill for £1,500 - as guarantor. Child says this is not the proper amount - it is not this much, and that they themselves ie the child, have the rent put by for when the court case is settled and the amount can be accurately calculated What does X do?
