House Asset Classification

I have owned my house for 15 years, and been married for 13. However, the deed has been solely in my name the entire time.
In the event of divorce, how is the house classified (Marital or Separate), and how is it distributed? The house is our only primary residence, and we have young children.

The home is your separate property, but your spouse has some martial interest. Any increase in value as a result of mortgage principal reduction, or renovations made during the marriage with marital funds is martial property to which she is entitled to half.
