Our company is owed money by one of our contractor companies who we helped with finance and provided us with personal sureties by the shareholders as security for the transaction. They have been making promises that they will pay for some time and we left it, but now we are getting worried about prescription. We are also unsure whether if we act against the sureties, prescription will be halted for the contractor or may continue and we lose our claim against the company itself. Can you advise?
