Can you help. A boundary fence that separate our IP with the neighbouring property is falling apart. Our tenant is screaming for replacement while the neighbour refuses to fix it, putting up reasons like we have to fix up cracks on our garage side wall first (on boundary line), including fixing that wall foundation to prevent future cracking. This fence is rotted and in pieces so repair is out of question. We are ok with replacement but would prefer the neighbour sharing half the cost. What options do we have regarding getting the neighbour sharing the cost? Thank you.
