My ex and I have joint custody of our 2 children. My 14 year old daughter lives in Arizona with her mom and my 15 year old son lives with me here in Indiana. A friend of my ex-wife's flew my daughter to Indiana for 2 weeks (one of which was her spring break, the other she is missing finals in school) without my permission. My daughter rides horses and participates in rodeos with this woman and rides the woman's horse. This friend is trying to say that because she paid for my childs airline ticket here that she has rights to her for the 2 weeks, however I was not made aware of when my daughter needed to fly out or I would have gladly paid for the tickets. Can this woman do this without my permission?
