prenup would have been a gud way to go then . If u 2 are working n there is no clear distinction of who is what . It is up to you guys to agree on what to do. You can go thro small claim legal office . like the TV show if u don;t want to go thro court. Therefore, it is always gud 2 have a job description or something written. If u were 2 keep business u should have bought the business and employed her. That way it would have been to your will whether to keep or lay her off. Now u need to share everything out of business especially if u have joint account. You guys don;t even need to be married. Once u r living on same place for long time with same address , it is possible for any other living partner to claim property. Hope this info helps ..
