I was in the very same position a few years ago, we had an agreement, but she was not sticking to it,I confronted her, she more or less laughed in my face, I bought a new company off the shelf from companies house, set up a new bank account, then went to see all the clients over a weekend or hand delivered a letter, telling them of a change of company name, informed my partner she was sacked. 3 times she tried to sue for unfair dismissal, loss of earnings and distress etc, etc, and 3 times it was thrown out of court, I have never looked back, I will never take on another partner, I would rather pay for extra help.. go for it, best of luck..
