My advise would be quite opposite to most so far. Only use a solicitor if its an absolute last resort, try talking to her 1st and see what she wants. Solicitors are parasites, you'll quite probably be handing over wads to one anyway if your both set on going down that road so try and sort out as much as you can amicable without using one. Stay calm and find out what she wants before putting your side. You never know, she might not want any part of the business , she might have designs on other assets you both have. Hope you can both sort things out without too much agro, better still, hope you can both find a way to stay together and be happy.
