Soldier made a big mistake picking the wrong friend to watch the house. However, the friend would need a contract to extend to the squatter.
If there wasn’t a contract, there would be when I got there. Just sayin’.
Did the soldier give power of attorney to his “friend”? Before deployment they warned us about how easily a general power of attorney can be abused.
Was his “friend” acting in his legal stead when he made the `contract’?
Anyway, extraction by bikers & guard dogs, with sheriff as witness, sounds like the best solution to a bad situation.
