Excellent advice, IMO, since the trigger for that chain of event would be the wealthy man’s death.
I would also call Foras into the situation once it came time to go to court. Foras is the one to speak to in matters of law and money together, in my experience, especially if you are getting screwed over.
Another perspective, though. You could try to use magick to un-screw your current beau’s transgressions, therefore being in a future position to direct the entire $3,000,000+ with your own hand through future magickal workings. I wouldn’t, but it is an option.
