<human>: A few years back, my Grandfather and Uncle sold their business they were partners in. My Grandfather originally started the business and when he retired, made his son (my uncle) a partner in the company and left it for him to run.

Unfortunately, my Uncle ran the business into the ground, and it was 500k in debt at the time of sale. The company had been in deficit for a few years, however, my piece of shit uncle and his wife decided to take advantage of the company and the fact that my Grandfather was personally funding the company out of his own pocket to try and keep it afloat.

My uncle was financing his own personal items through the company unbeknownst to my Grandfather at the time. This includes his own truck, car for his wife, car for his daughter, gas cards for his family (unrelated to the business), RV, boat, atv etc. the list goes on.

At the time of sale, the company 500k in deficit, Once the sale was settled and assets and inventory were sold, the remaining debt is 150k.

My uncle has completely walked away and left my sick Grandfather to harbour all of the debt, which he is now paying off via line of credit from the bank. My Uncle on the other hand, is completely denying that there is debt, and that he did nothing wrong (I have seen the books).

Not only, has my Uncle screwed over my Grandfather, he also left many suppliers with unpaid invoices that have now gone to collections. Every time one of the collectors tries to contact my uncle to get paid, he changes his phone number and gives them my Grandfathers phone number, leaving my Grandfather (who is very sick and dealing with my sick grandmother as well) to deal with collections and pay off more debt that isnt his.

What can legally be done to either make my Uncle pay or take responsibility, or somehow make him legally responsible for all the debt.

Provide a brief overview of the text.
