Can a creditor take my car?

Question Details:

I have a creditor that has a judgement against me for $8,000 that I have not had contact with for a couple years. I have been out of work and unable to seek work because I take care of my mother who is crippled and sick. I received a letter threatening to take my car. My 2000 car is barely working and I share it with my brother and use it to take my mother to appointments. I am totally dependent on the vehicle and I also co-own it with my brother. I hate my situation but I simply cannot negotiate when I have no income. I intend to eventually pay off the debt. Important Notice
