Does anyone have experience with how it unfolds. Right now I am just waking up every day not knowing how my LLC gets sued and what kind of letter I will receive etc. My lawyer said not to worry as LLC is my protection but I still want to hear if someone has experienced it or know of someone who have gone through this.
I had a LLC (not in trading) that failed. The LLC left debts of about €60k. I consulted with lawyers. Only one out of four creditors bothered having their lawyer send me a letter; the others didn't even bother with that. In the absence of any personally guaranteed debts and given the absence of fraudulent intent or gross negligence on my part I was in the clear. The LLC of course ceased activity. If it is refinanced it would have to pay its debts. I let it go bankrupt.
Your company lost 50k and left a debt of 25k that was taken up by your broker. Absent as I understand that they are, personal guarantees, fraud, gross negligence, you are completely in the clear. The LLC of course is dead unless you choose to take up its and your broker's loss which seems pretty stupid.
As an additional consideration, if I understand correctly, the 25k loss was incurred in consequence of your broker's systems not being able to cope with extreme volatility and failing to execute a normal stop out of your account when it was still in the green. If so it is their fault really that led to the negative 25k balance! One could argue that weren't for the broker's failure to execute your margin call in a timely manner your LLC account would still be in the green which would suggest rather it is the LLC that could sue them. Of course verify this with your lawyer. It may not be possible in practice because in all likelihood the broker would have legally protected themselves against such an eventuality in the brokerage contract.
Don't lose any sleep over it. Let the LLC go bankrupt. Don't say or write anything to your broker without consulting with your lawyer. When my LLC was faced with the impossibility to do business I called up the creditors, illustrated to them the situation, the unfavorable prospects and the unrecoverability of their credits. You don't even need to do this since it is their fault.
I would suggest you make sure they refrain from taking any step which might bring prejudice to any future venture of yours. I would consult in order to part ways amicably with your broker... something along the lines of "unfortunate outcome... their technical systems didn't cope... you won't pursue the matter unless they do... personal finances don't allow to take up the LLC debt they created... no longer conditions to do business together... keep confidentiality about entire matter (in both parties interest)"
