A Florida court will utilize the principles of international comity recognize a judgment of a foreign nation if it is convinced that the parties in the foreign court received fair treatment by a court of competent jurisdiction "under a system of jurisprudence likely to secure an impartial administration of justice between the citizens of its own country and those of other countries...." Hilton v. Guyot, 159 U.S. 113, 202, 16 S.Ct. 139, 158, 40 L.Ed. 95 (1895);
Comity is a very flexible doctrine. The basic rule is that the other parent must have notice of a legal proceeding and the opportunity to appear and present his or her case, before a neutral decision maker/judge. If this opportunity was provided to your spouse, then the Florida court will enforce your PPO. Otherwise, the court will enforce the Florida order -- once again, assuming that you were given notice and opportunity to appear and present your case to the court.
What this boils down to is that if an when you return to Florida, you will have to show the court that the PPO was ordered under the doctrine of comity, and that your spouse simply failed to appear and present his or her case. Note that an appearance could be had by telephone, if a physical appearance was impraictical.
Frankly, when you return to Florida, you will need to hire a family law attorney to prepare your case. This is one of those times when the failure to have competent legal representation is almost certain to doom you to failure.
