In principle, you would hope to be able to deal with the problem in the same way as with any two employees who don't get on together. You may be able to talk through the problems with the individuals concerned and negotiate an agreement. If one individual is clearly behaving inappropriately - for example, deliberately sabotaging the other's work - you could invoke your disciplinary procedures. It may be possible to organise for the two individuals to work in separate areas of the business, minimising the opportunities for conflict. Or you may decide that the best solution is to ask one individual to resign.
In practice, solutions like these may not be easy when you are dealing with members of your own family. One option is to use an independent mediator to negotiate a resolution of the dispute. Where mediation fails, it may be possible to use an arbitrator - who can impose a solution if the parties cannot agree among themselves. Ideally, you will have planned ahead and family members will have agreed to dispute resolution procedures as part of your shareholders' agreement or family charter (see question 2).
