Tree limbs overhanging my property. I asked him several times to cut and he refused. he is now selling. What cn I do?

As a general rule, you can trim the limbs hanging over the property line if it will not kill the tree. I would hesitate, however, unless you are very sure of exactly where the property line is located. For good measure, you may just want to wait until the new neighbors move in to see if you can get it accomplished without any dispute.

As a legal matter, a property owner generally is not responsible for keeping branches from overhanging neighboring properties. You should not expect payment. You also must not enter your neighbor's property to perform the pruning, or you risk being liable for trespass. Finally, as the previous attorney mentioned, you may be liable if your pruning destroys your neighbor's tree (e.g., if you render the tree lopsided and unstable or you remove too much of the canopy so that the tree is unable to recover). As a practical matter, you should think about the relationship you want to develop with your new neighbor. "Welcome to the neighborhood, you owe me $500.00 for pruning your tree," may not go over very well.
