We are building a new 200 foot wall between us and our neighbour. We are replacing an existing old blockade. How can I convince him to split the cost since it benefits both of us. My husband and friends are willing to do All the work.
Answers:    Explain it to him in recent times like you've done here.
Before doing any building I would homily to your neighbor and tell them that you would close to to replace the old obstruction and was wondering if they would be interested contained by going in beside you on it. If you both go contained by on it you can build a better fence. Presentation is the switch. Even though its making his yard look better you dont want to upset him off by making it nouns like your doing him a favor.
