My neighbour and I share a party wall, can I force him to share the cost of repairing it?
Is this a party wall or a party fence wall in other words a wall dividing your gardens? If it’s the latter the cheapest option may be to pay for the work yourself, or even build a new wall entirely on your land unless you have a good relationship with your neighbour and he or she agrees to chip in. Under the Party Wall (etc) Act 1996 you can force your neighbours to pay their share if you serve the correct notices, but it can cause aggravation and expense and in the long run it may not be worth it. If its a party wall dividing buildings you may have to explore this option.
