I have had two experiences regarding this type of illegal Tresspass perhaps not quite in the same vein as the Travellers but it still amounts to the same thing.
1] A licence agreement with a chap for some land allowed for the monthly use of same.The Licencee proceeded to put a Mobile home on the Land and live in it.The Local Planning Enforcement Officer arrived and I explained to him that the Licencee did not have my permisson to use the Land for this purpose.He told me I must get an Eviction Order from the Courts .That cost me three thousand pounds and he stayed for another four or five months while this was implemented and no Rent came in this period.
2] A very Wealthy Business Man took a Unit from me three Years ago on a monthly Licence.He informed me he was leaving at the end of the Month I re let the Unit but he would not Vacate saying he wanted more time on two further occasions.The incumbent Licencee was under pressure from a Contract he had taken to use the Premises to the tune of £150,000.I last week went to Lawyers for you on line,cost £25, Answer: A Tenant has rights in Law to possesion of Land as does a leasee.A licence to use Land or Property is suseptable to one days notice and if not complied with the Goods can be removed taken to a Lockable premises and money demanded for the removal and Storage of such and if not paid the Goods can be put up for Public Auction. The Licencee went to his Solicitors and will be out this Friday,Cost to me £25 and two Letters.
I would do the same with Travellors,I would give them 24 hrs notice and have a Witness present then remove their Property as Advised above and I would tell the Police what I was going to do.
The Legal Fraternity are always looking to enhance their ways of soaking the situation for their own ends, The Law usually has been written with a way of sure outcome ,Lawyers try and cloud it.
