Legal Question in Family Law in Florida

Are you on the birth certificate? No you can not file a missing person. Find out where she is by locating her other family members - one does not just vanish when children are involved.

Once you have located her - if she has not established residency where she is - then file an action for custody of the children in this state and have the sheriff serve her in the state where she is. She will have to come here to answer if she has not established residency in another state. Otherwise, you will have to file in the state where she is located.
