Is there any mention of the parking space in the purchase contract or title deeds.?
You mention a landlord, do you have a lease? If so, any mention of the parking space in the lease?
Have you regarded the space as yours, I.e in your ownership? Or merely a right to park there?
Ok. Do you have w copy of the title?
What is the relevance of the landlord?
Do you have any record / evidence of the previous owner parking on the land?
Do you still need help?
