Forming a Corp. during failing mariage

I would like to start a business, likely a corporation. However I am uncertain if my marriage will continue.

My (limited) understanding of WA law is that he would be enitled to half of the our money and assets upon divorce. I feel comfortable that any of our money or his time that goes in to this business should be considered if a division of our assets occurs. As I do about monies spent on property he co-owns.

Fear that I would have to disolve or sell the business to compensate him for its value at the time of divorce and potential impact on partners or employees prevents me from moving forward with this project.

How can I prevent my husband from 'owning' part of the business, rather than just being entitled to his portion of our money and compensation for his time?
