Paying child support from money made on flips

[Steve Cady]

Not looking for official legal advise but wanted to know if anyone has run into this before.  I work a standard 9-5 which is what my child support to my ex is based on.  How does flipping houses play into that.  Does anyone know if that capitol gains money could be interpreted as income as it pertains to child support.  Has anyone experience an increase in their child support based on money they made flipping?  I'm not trying to dodge anything.  I'm just wondering what I can expect.  Thanks in advance for the comments!
