I had a 34% share in a franchised optometry practice. My partner and I had a fall out and due to differences we couldn't resolve, we descided to split. I resigned from the company and sold my shares to my partner. I was basically only payed out for what the fittings and fixures of the business are worth - approximately equivalent to six month salary. In the sales agreement which I had to sign, there is a restraint of trade clause effective for three years which prohibits me from practicing in the same town. Initially it didn't bother me because my plan was to move to another town and work there. My situation has now changed, my wife is pregnant and it is difficult for both of us to find work elsewhere. My wife has a good job in town and we also own a home here. My best option would be to open my own practice in town. How enforceable is the restraint of trade clause? And what's the worst that can happen?
