Hello and thank you for your question. I will be very pleased to assist you. I'm a practicing lawyer in England with over 10 years experience.
You mention a landlord. Do you presently own or are you looking to buy a piece of land with ineral rights please or just mineral rights alone?
So to be clear the owner does not want to sell to you which you accept but you are hoping you may be able to purchase the mineral rights to the land anyway. Is that correct please?
Apologies for the delay in reverting to you. Have you had the opportunity to obtain the title entries (deeds) to the property from the Land Registry?
