Once upon a time, I had a legally binding contract with a company HQ'd in Europe. They chose not to pay (they were in financial trouble), even though they were happy with the service. The cost of retaining representation in that company to defend the contract was very costly. I took the loss, and that was the best way to win in that situation. I was referred to this company from a passed business relationship and friend. You never know! I have also worked with other companies in Europe over the years. Never had a problem with this one exception. I hope Victor has really good advise for you. They only thing I could have done differently was deeper research into the company's financials. Wish you good fortune.
