I think you're spot on, Lash. I'll take that a step further, and opine that Dina is very likely having serious financial problems.
JMO, but I suspect she is very far behind in paying her attorneys, and that's why they have withdrawn from representing her. From her voluminous legal filings, motions, etc in all these cases, over the last 12 months alone, I'd guess she has had several hundred thousand dollars in legal fees. Her chosen attorneys are "top tier", and typically bill hundreds of dollars an hour. Divorce settlement money won't last forever at that rate, and she has no apparent source of income. My guess is she's falling far behind in paying her attorneys, and we will start to see more evidence of missed filings, and other "difficulties with her legal representation" in all 3 of these lawsuits.
