There are rules about this. You have to be married for a length of time, and it only lasts a certain time. There are few "musts" for the court in this situation.
You sound like you don't have an attorney. Trust me when I say that, as expensive as they are, you want one when getting a divorce. This is particularly true when the other side has one and you can't separate peacefully.
The laws are specific on towing in Texas. They have to have the signs on either side of ALL entrances. They have to be conspicuous.
I do a lot of tow suits, and produced a quick youtube on it - see the link below. The first step is to ask for a tow hearing, which is cheap and easy. The second step is a civil suit, which is much more work, but can wind up rewarding you with a $1000 plus 3x the fees.
It is most likely the case that these debts would be discharged in bankruptcy, and your benefits would remain untouched. It is probably worth talking to a bankruptcy attorney about the matter. We're easy to find!
As previously mentioned, a perpetual Chapter 13 can help you take charge of this and other debts, so you can make ends meet. But this may not be necessary, as you may be judgment proof. Best to chat with a local attorney (ahem...), and have him look at ALL your debts and the full scenario before making a decision.
You CAN garnish a bank account before judgment, but only under particular circumstances.
You should be able to find an attorney that can listen to your questions and explain it to you for less than $100. If you call the Houston Bar Association, I suspect that you can find an attorney who will listen to your story and answer your questions for even less than that. Be aware that any kind of suit like this will run you more than $1000, and probably triple that.
This could be a very complex situation. You need to see your attorney.
Your children are threatening you with jail? It is HIGHLY unlikely you have any likelihood of going to jail, as you've not deliberately mislead the court, so stop worrying about that. Just see an attorney and bring all your paperwork.
This will also be one of those times where having a good bankruptcy attorney makes a difference.
