Does anyone know how the state of Florida defines child abandonment? I can't find anything in the state legislature. Long story short.. I'm a foster parent and we're heading towards adoption. The father 'popped' up in court yesterday asking for visitation after 20 months of no visits or contact with the children. One would assume (I know it's never safe to assume) that he had abandonded his children after so much time had passed knowing full well where they were and how he could have had visits.

If anyone knows the answer to the definition or if there's a timeframe it would be greatly appreciated.
