Marital property or not?

I have owned my home since 1999 and made the payments with my VA disability check. i have been married for 1 1/2 years and she left and is threatening to take the house from me and my son( not our son, just mine, she is the stepmother) is the house considered marital property since i had it before the marriage began? i did not fully understand the NCGS 50(b)(2) section on what is marital property and what is not…
Thanks for all your help,

The home is your separate property, though she may have a marital interest based on any active appreciation in value that occurred during the marriage. An active increase in value would be principal reduction on the mortgage ( I assume that would not be much over the course of 18 months), or any renovations which occurred during the marriage which increased the value of the home.

Thank you so much for your help…

You are most welcome. I wish you all the best.
