Re: Money stolen
have the goods or services been delivered to the customers that party 1 ( let's call him George !) sold to. If not is the agreement of sale of these customers with George and if those customers do not get the goods / service, they will pursue George?
Looking at the bigger picture, are the customers likely to be repeat customers and is it important to maintain the reputation of the business? Is it your brothers good name that is being used by George or is he in fact acting as a reseller as if the goods / services were his to sell?
