Who owns the website? Dissolution of business assets?

I entered into a business partnership with someone and the partnership dissolved. Our initial agreement was that I own 49% and she own 51%. We never signed a notarized document, I only have witnesses to her saying this and an e-mail with her stating this. We worked together for two months and during that time I created a logo, a website, business cards, and a demo. She became upset with me over something trivial and told me that she wanted to demote me to a "subordinate" position, at which point, I told her I no longer wanted to be involved in the partnership. I asked her to pay me back the cost I had put into the website which was half of the hosting fees and the cost of the template. She will not repay me, but threatened to sue me because I had taken my name and picture off the website. In her words, I had caused damage to her company. What I''m wondering is, who owns the website? Does she have any legal bearing? Could I take it down if I wanted?
