Between my drive and my neighbours drive there is a shared path that leads up to a door on my property. The problem is one of my neighbour's visitors keeps parking on it and partly on my drive. See attached diagram. The shared drive is in the centre of the picture over the shared path and partly on my drive. Right next to their car is neighbours front door on the side. Me and neighbour have part ownership of the path.
Am I being unreasonable to expect them not to partly park my drive and across the shared path? I'm concerned that the path could end up getting damaged by them driving a car over it, only I feel petty because they say they are disabled, they can walk but slowly. They also do it when their drive is full of cars due to people visiting them.
I'd appreciate your thoughts, vote I'm being unreasonable if I'm being petty
