I haven’t yet identified a DivorceInfo Network Lawyer for Florida.
You probably should start with the excellent site provided by the Florida Court System, www.flcourts.org. You’ll find there a self-help center. Among other things, it contains the forms for divorce and related actions.
You can also use Florida Divorce Online, which offers the following advantages: (1) You prepare the papers online without paying any money; (2) You decide only after the papers are prepared whether you want to pay for them; and (3) the charge is only $89.95 for all the required documents, including the marital settlement agreement. Looks like a pretty good deal to me.
Here’s a nice child support calculator from Steven A. Leitman in Neptune Beach near Jacksonville. The most comprehensive source I’ve found so far is FloridaDivorce.com. When I visited, they had this annoying window that popped up demanding to know my Florida zip code, but once I lied and gave them one (you and I both know I don’t live in Florida), I was able to use the site okay. The tone is a little gladiator-ish, but that’s probably to be expected.
