S.,
Do you know the name/address of the company the person works for? I had a previous situation like this, only the person was in my house and not paying, then later left the property still owing. Now I did initially sign up with a property attorney, who was able to start contact with the person as far as making arrangements for them to pay what they owed, and the attorney would get a percentage of whatever was recovered. However, it seemed at times that things were progressing slowly, so I took matters into my own hands and contacted the persons employment, via their HR/payroll department. By doing so, I found out this person had a history of not paying items and there had been numerous garnishments of her wages since she'd been working for the company. So basically, I had to get in line to wait to have her wages garnished. But I got all the paperwork submitted directly to her employer and by working with them, we were able to submit proper court papers to get a garnishment started. I would say you could get the majority of the work done on your own, as far as contact with the employer, and then bring an attorney in later on to help file the court papers.
