If the dispute cannot be resolved, in order to avoid allegations of trespass and damage to goods (i.e. the caravan/lodge and the possession inside) you would need to bring a claim in the County Court for possession of the pitch but be prepared for the proceedings to be defended and for any possible …counterclaim for damages for unlawful termination. Legal action is expensive and can be long drawn out. You should take legal advice on the risks of pursuing legal action before bringing a claim. If appropriate, make a “without prejudice” offer of settlement.
