It is from the UK’s National Health Service (NHS) or Ireland’s Health Service Executive or public voluntary hospitals that you are likely to start your expert witness career. Be mindful of your contractual obligations. You cannot get on with your medicolegal work and say nothing or your probity will be in question. However, many employers, in agreeing a job plan, are happy for consultants to do some medicolegal work in ‘work’ time. If you want to do it on your employer’s premises, you need permission. Your employer may want payment, but this will be a deductible business expense.
