A mass exodus of possessions is a clear signal that shit is going to go down. I don't have many *things* to begin with and have exhibited behavior of throwing/giving many things away in the past, so continued behavior wouldn't throw up any signs.
Financial accounts, otoh, aren't easily hidden, thus, I don't know what to do about them. Perhaps overpay for services of some kind...not sure. But I don't think selling a car to your mom for $100 is going to cut it. They'd try to get money out of your mom.
This process is one that makes several months, not weeks or days.
