He received a large portion upfront, but was given a promissory note for the rest which was a very large amount. It was to paid completely by 2005 in semi annuall installments. The promissory note was signed by his partner. He has refused to pay and we are now living in a different state. The partner had many assets and still does. The business slowed down, but this was a prommisory note. Can he still collect on this which was drawn up with attorneys at the time who are witness to the agreement. He still has all paperwork regarding buyout information. Would he be entitled to damages or any interest and penalty from his partner. Could this be done on a contengency basis and could he do it in the state we now reside in.
