My ex husband and I have shared custody of our two daughters. We've been divorced for 4 years. I'm recently married and my husband is in the Army. We're looking to move to Texas and have provided my ex the 30 day notice. He of course does not want the girls to move...I hear its up to me to show why it's in the best interest of the girls. It's easy, I'm their Mom and they love their Stepdad and the family environment that is in place. My ex and I are both good people and parents...he's now trying to get primary residential custody from me. Any suggestions to how to present this in my favor to the courts.
