£30,000 in legal feels hanging over the family. Let's hope that tractor increases in value rather quickly.
One thing that occurred to me was that if Helen does report Rob and the police investigate, she will be eligible for criminal injuries compensation. It's unlikely to be £30,000 but it's possible that both she and Henry would be awarded compensation. It's given if the victim cooperates with the police investigation, even if the perpetrator is not either tried or convicted.
Plus, Rob really does have it coming!
