When starting a business you can, in your naivete, create many problems unknowingly, which will only begin to affect you and your business further down the line, that is why, seeking an understanding of as many perspectives is important. One of the most important is unquestioningly that as from a legal basis. Having a clear understanding on issues like shareholders agreements and partnership arrangements is a must, as is knowing the names you can legally share/trade under, and the terms of financial agreements you have with your sources of finance, and tax practices you should be using. Also, when starting a business, you will likely be in a very vulnerable position, and as such you should seek legal consultation on the terms of your leasing for your premises; so you will not be surprised when your landlord suddenly increases the rent.
Managing a business can be difficult, particularly with the legal issues the modern day employment laws are concerned. In the UK, employment laws have become increasingly more stringent over the last few decades, to the point where it is very difficult to understand where you stand by yourself. Fortunately, this problem for businesses has been met with the rise of new areas of legal representation; it, like so many other things, can be outsourced to experts on the particular issue you are struggling with; whatever the problems and whatever the solutions, they will seek to provide. Understanding the process by which you can go about firing people legally is a must have for any employer, and hiring someone to help will benefit this understanding, and also provide you with a separate entity willing and able to corroborate your side of the story. In the long run, this is an essential relationship to have.
