My question involves divorce in the State of: VA

I received a $500,000 inheritance when my dad passed away. I have been told that this money is not marital so long as I put it in a separate account - which I did.

My question is this - this nest egg has grown in value by almost $100,000. I am in the process of divorcing my wife but nothing is in writing at this time. Is she entitled to 1/2 of the increase in value?
