Changing a Child's Name: Changing Name when Non Custodial Parent Moves Away

My question involves name change laws in the State of: FL



My ex recently moved out of state and gave me 10 days notice. We have a 2 yr old daughter together. I want to change her last name to mine since he is now out of state and won't be dealing with medical and school stuff. What is the likelihood of this happening since he left? Hes refused to changed it in the past but now he left.
