Q: Lawyer knows his client is at fault. Shouldn't he advise client to honor his obligation, instead of attacking victim?

A: I think your question involves malpractice? If so, you should first consult the Idaho Rules of Professional Conduct: https://isb.idaho.gov/bar-counsel/irpc/ Look first at the lawyer's B's duty to his clients. Then look at the lawyer's B's duties when working with 3rd parties. Your question seems to equate the failure of Party A to give adequate notice of his intent to remove soil, as his "fault" but does not specify what Party A's real fault is? You wrote, "After the damage is done," what damage? The failure to provide statutory, advance notice of his intention to remove soil or ? The middle part of your question concerning the 2 letters that Party B's attorney sent to Party A's attorney. What did these letters say? I suspect that these letters may answer my first question? What damages were suffered by Party A's failure to provide adequate notice? The final part of your question involves Party A, being at fault for removing soil and his obligation to repair the "damage" in an "honorable and timely manner?" There is nothing in Idaho law which requires that a party do his obligation in an "honorable and timely" fashion. After writing 2 letters to Party A, explaining his duty NOT to remove soil between the parties dividing lines without adequate notice etc., is your attorney telling you that there is nothing you can do to keep the Party A from failing to remediate the property? If this is your last question, please find another attorney. This is a fairly common problem and the land owner who has his property "dug up" has the right to remediation from the digger.
