How can I legitimize my home business and place that business within a trust while still protecting it from divorce proceedings?

My primary sources of income are my home business, driving for Uber, and giving guidance to people on how to make money from on demand jobs. I would like to consolidate all of that into a legal business, partially for tax purposes, and put the business into a trust. I also want to make everything business related the property of the business. My main concern is the divorce I am going through right now. Since my wife left I have found another partner and the business we have was her idea. She also manages the business by herself with little help from me as I am busy with other endeavors. I would like to form a legal business out of what she does and place that business in a trust so that my previous partner cannot take what my current partner has worked so hard to build.
