If they are healthy trees you have to trim the extended branches in your side of the property.
Get an arborist to evaluate the trees. If the arborist says they're unsafe, send a copy of the report by certified mail to the homeowner and keep a copy for yourself.
If you live in a municipality that has an interest in trees on private property, send a copy to them, too.
Regardless, trim whatever you need above your property so long as you don't kill the tree.
