I owned my house before I got married. How will that be handled in my divorce?

The normal rule is that the marital property is to be divided equally. There are exceptions to the rule and you should discuss exceptions with your attorney. "Marital property" is normally considered property that is acquired after the marriage. Therefore, any appreciation in your home will be considered marital property. This assumes that joint assets were used after the marriage to pay the mortgage and taxes on the property. Your attorney will be able to explain this more specifically for your case.
