To clarify a few points:
1) It's not that we would only plant the tree in the spring. The tree can't be moved or planted now. It HAS to be done in the spring.
2) We specifically asked in our email to him that he either provide a paid receipt to the nursery we chose or provide us the equivalent in cash/check. I didn't copy/paste our email here and just didn't put that specific detail when I summarized the email
3) It's not the tree valuation PLUS 3x the damages. It's 3x the tree valuation. What we are asking for isn't far off from the maximum. But it still doesn't include him having to pay an attorney on his part and subsequently paying for ours plus any other costs. So it's still cheaper for him in the long run to get it done this way. Plus, as a contractor, he can get these trees for less than I can so it ends up costing him less to get this done on his own vs. paying out the amount in cash (I would assume).
I agree that "quick resolution" has passed. But, there's still a chance to get this done between us. I agree that he has probably reached out to his lawyer and that's why we probably haven't heard back from him over the last few days. I also didn't put a specific time frame in our email from last week which was why I specifically asked to hear one way or the other by the end of this week in the email we sent last night. It's possible in that timeframe (and after hearing from his lawyer) that he realizes he needs to get close to where we are or he may be on the hook for more. So, a few more days in waiting for that doesn't really change much.
If he decides against that or doesn't respond at all, then we'll be getting help from the attorney. But, at that point, I'm starting to pay for services. First, for a letter, then beyond that any more time needed to negotiate or file suit. Ultimately, he would be responsible for these costs if we file a lawsuit, but if not, then I'm paying out money to recover money for which there's never a guarantee (despite this being pretty open/shut). So, from a financial standpoint, trying to get this done ourselves is still in our best interest.
