It sounds as though the neighbor hired the tree trimmer, and hopefully he made sure the man was licensed, bonded, insured in which case both of you should be clear of liability for injuries unless someone did something to cause the fall. If the worker wasn't properly licensed, then the neighbor became, in effect, his worker's comp insurer by hiring him. This is why it is unwise to hire unlicensed contractors. If the worker sues your neighbor and/or you, it will be up to him to prove who is liable and for what. It will also be up to the both of you to work up your defenses why you are not liable. All this is very fact-specific, and should be handled by a competent attorney when the time is right. As between you and your neighbor, since you are paying for some of the work, even though you didn't sign the contract, it will be up to yourselves or the judge or jury to work that out. With few facts to go on, this answer cannot be considered specific legal advice, but only a statement of general principles. A visit to an attorney with all the evidence would be necessary for a full answer.
