If they file a bankruptcy, your only relief will likely come from any funds that go into the bankruptcy estate (if any) and you will have to share that pot with all the other creditors, so your best chance then may be a percentage of what you are owed. I am not sure it's fair for them to ask you to accept 50 cents on the dollar without them disclosing their whole picture (all assets vs. how much other debt they have). Depending on how much your judgment is for, it may be worth your time to go see an attorney who specializes in creditor's rights to help you through this.Ask a similar question
Attorney Patton's advice is correct. I would only add that you should keep your eye on this and make sure that your judgment is correctly scheduled on their bankruptcy petition, that you file a proof of claim, that you go to the creditor's meeting, and otherwise pursue your rights.
It is really up to you to decide if one-half now is worth it. It may well be, depending on whether or not they are telling you the truth about their financial condition.
The only other thing I can suggest is that only if your judgment has counts for fraud that were in fact included in the final judgment, then this would not necessarily be dischargeable in the bankruptcy. However, you would need to file an adversary proceding in federal bankruptcy court to get a judge to rule on the issue of dischargeability.
