Yes but they’re chaotic too. Plus she may not have known exactly when the baby was due, next thing she’s in Labour the wrong side of new year?I understand your thinking but surely they could be putting plans in place whilst carrying on with their "normal" life. Ie organisation fake documents for MG, travel arrangements, maybe securing a place to stay abroad. No one would be any the wiser. He could have done his last signing on, they leave the same day or day after and by the time anyone realised anything was amiss, they would be long gone.
I've also wondered though, if CMs trust fund money wasn't quite as much as we all assume. She got a £19k payment in December, but 2 further payments of 3k (again in December) and just 800 in January. She said they had fines from the motor home, was it 25k? and her family wouldn't help. I'm wondering if the December payments were possibly annual payments rather than regular monthly payments. The trust have refused to pay for her legal representation and past legal issues (the fines) so maybe her cash flow wasn't quite what it appeared. I know absolutely nothing about trust funds BTW its just my own ponderings.
