You can protect your business by understanding how much your business is worth prior to the time of the marriage. Because a basic tenet of divorce law in Ohio is that which was yours prior to the divorce stays yours, and that which is created during the marriage is divided between the parties. You actually might seek the counsel of an attorney – a qualified attorney – to help write a prenuptial agreement that will protect those assets that you had prior to the marriage, and protect those assets as you go into the marriage.
