If a child is with the father more than the mother can he take custody?

Hello and thank you for asking. You have done a great job in documenting all the incidents as they can come in handy in the case for your son. So this girl he is/was with has a child with your son, for which he pays child support and also help raise her other children. The girl desires to leave your son and move out of the house. You can certainly contest the move for your grandson and he can do the same as his father. However, you will need to prove to the court why he or you should get the custody of the child where she elects to take her kids to a proven narcissists house. If you think she will contest your son having primary custody than you should consider working with a competent and aggressive lawyer to get what you want to be done. I hope everything works out for you guys. Please keep in mind that not all lawyers are the same, therefore be very cautious as to which attorney or law firm you chose to work with.
