You can file for divorce in Arizona as long as you meet the jurisdictional requirements for residency in Arizona, which is 90 days. You can hire a lawyer in Arizona to represent you during your divorce as long as the process occurs in Arizona. Your husband may be able to file for divorce in Florida if he meets the Florida jurisdictional requirements. If you have children, then your children will need to have been in Arizona for six months so that we have child custody jurisdiction. If the two of you own property in Arizona, then we can resolve those issues also, but if your property is out of state things can get a little tricky. As usual, many things are very fact dependent and I would recommend consulting with a lawyer to get specific detailed answers for your exact situation.
