This must be very frustrating. It will be difficult to say with certainty without reading the deeds. If your neighbour has a right to use the accessway in order to access and egress her property it may be difficult to prevent visitors using the accessway.
I am happy to read the deeds to advise further.
Do let me know if you have any further questions or queries. I would be happy to assist you further.
Please can I ask you to take a moment to accept/rate my reply. Otherwise I will not get paid for the time I have taken to consider and type my reply. Thanks.
Thanks. This is standard wording. This would extend to your neighbour allowing visitors to use it.
You cannot really put a lock on the gate without going the neighbour a key. But the bin men would be denide access if you did, unless you come to an arrangement with the neighbour that bins are put the otherwise of your gate the night before collection.
You can use security and the burglary as a reason.
Although the neighbour could refuse and say you are restricting her right and you would have to remove it.
You can, as I said you can and need to give her a key and come to an arrangement regarding the bins.
I would suggest giving her one copy and retain the master.
