My ex is not paying child support. In Florida can I withhold time sharing / visitation?
The short and easy answer is “No.” You should not withhold time sharing because the other parent is not paying child support.
It doesn’t matter if the child support is court ordered or not.
Withholding time sharing because the other parent is not paying child support is specifically prohibited by the Florida Statutes and is looked on unfavorably by judges.
The judges are usually of the opinion that the child benefits from a good relationship with both parents.
If the other parent is not paying child support, you should look into filing a Motion for Contempt.
