Please can anyone clarify this situation? I have a verbal agreement on a 5 acre field I've been there over ten years now and always paid rent by cheque every single month . I've maintained grassland and made hay off it. My horses have been on it continuosly with no break. Do I have a tenancy now? The owners son wants to dump and compost garden waste on a part of field and I've said no it's dangerous to my horses and whole field is rented to me so I have rights to refuse this intrusion? Please help I'm losing sleep over this as feel there is ulterior motive at play here?
