Good to hear from you again. I'm sorry I didn't get back with you earlier, but I've been traveling all day, and actually am writing this on my phone. I did have a good holiday, and I hope you and yours did as well. I am sorry to hear that you didn't get everything you asked for from the Better Business Bureau, but at least this contractor
will hopefully pay you something. And, I agree with you, with those types of practices, he's likely not to be in business much longer.
In answer to your questions, while the H OA could theoretically take the car if they got a judgment against him for the past due amount, I don't see that as likely. This is because there are serious costs involved in levying a vehicle to satisfy a judgment, and in this case the vehicle is worth maybe $6000. That covers roughly half of the past due balance. This is of course before their expenses to take the vehicle. It would be more likely that if the HOA were to get a judgment against him, they try to do something such as garnish a percentage of his wages.
This is a civil matter, not a criminal one, so they cannot put your son in jail for this. The worst that can happen is that a court finds that he does in fact owe the money, and then there is a civil judgment against him.
I am out of town until the end of the week, and will have limited to no access to my computer during that time. If you have any follow-up questions, I am happy to answer them, and you can reply back to this thread. Just keep in mind, that I may not reply until this weekend.
I hope that this helps.
