This is a case from 2017 and concerns a very successful businessman who made £140m through his enterprise while his wife "stayed at home" to bring up their children and look after the home.  She fully supported his enterprises however, including moving to Japan to allow his business to grow, and the Court of Appeal found that she had equally contributed to the marriage.  We see in our work that quite often the larger financial contributor finds it very difficult to understand that concept of equal contribution in such cases and this case quite neatly sets out the courts views in this respect.
