A financial planner or independent financial advisor can put into place any financial agreements you decide. What will you do with the pension share? What will you do with cash and shares? How will you invest any money you get for the future? But, more importantly, they can model any plans you have for settlement using financial modelling computer software. This is very helpful in working out a fair settlement.
This kind of activity is regulated by the Financial Services Conduct Authority (FSA).
Important to note, a lawyer is not allowed to advise you what to do with your money, where to invest it, or what shares to buy unless they are also regulated by the FSA.
