My question involves a child custody case from the State of: NY

I have a 6 year old daughter me and my ex live in NYC. WE have joint legal custody and she having physical custody, while me having every other weekend.Th mother said was getting married in Dominican Republican, and i told her u have to bring my daughter on my visits, she ok that my daughter would be back..She lie to me and she left to DR, October 13 and she coming back on the 22nd...I did not give her permission to do that..

She has been violating visit since 2010, i believe this is enough.. i want in change in custody... this the reason i didn;t want to sign the passport, but i took her word for it, she even put me in court for that, and told the judge my daughter would be back... all a lie so what are my options here???
