I bought a holiday caravan on the coast. Three months later the site produced the most draconian set of rules I’ve ever come across, including a surcharge for late payment of fees. I’ve refused to pay this. Am I bound by the rules in these circumstances?
Presumably you signed a licence agreement when you bought the caravan. If the agreement gives the site owner the right to change the rules, then you will be bound by them. You should study the agreement carefully, since it creates obligations on both sides and will detail your options if, for example, you want to leave. Certainly if you were made aware of a surcharge for late payment before it became due you will be liable to pay it. Show the agreement to a solicitor if necessary.
