any update SB?

Two separate issues here.   1) A non compete clause may be enforceable and the exact wording needs to be checked with a solicitor.   2) If he left invoices of customer details readily visible on the desk/ counter, si the first breach point not in fact your brother? I'd say he is on dodgy ground with that one.

Have they admitted in writing liability,?   And name and shame please    Also how did you pay, outright or by credit?   Dx

Thanks dx. Will follow your advice.

You totally ignore DWF no matter what    End of. No exceptions.   Dx
