Thank you for your question
My name is ***** ***** I shall do my best to help you.
I am afraid that if the Estate Agents do ever link the buyer to the request then yes they can invoice you at any time and under the terms of the contract you are liable to pay
Please ask if you need further details
I have always suspected that Estate agents do indeed run a check after a year - but that is suspicion not knowledge.
I don't think I would take the risk - but it is a personal choice!
Hopefully it will be sold swiftly
