Once you start running a business, you are likely to find a whole host of legal issues that must be solved quickly to avoid fines, litigation and loss of reputation, amongst other things. The best way to do this is to have lawyers on hand so you can get the advice you need quickly. Keeping the same business solicitors is best, because they will be familiar with your business and know exactly what is likely to be a problem and how to avoid it.
It is far better for your business and your peace of mind to avoid a problem than have to solve it. Working to solve a problem will take a lot of time and effort away from running the business, even though this must be done. Avoiding the problem in the first place will cost a lot less, even when you take into account paying your legal advisor.
