If she has never lived with you in Florida and has no ties to Florida, you can file for a divorce in Florida, but Florida only has jurisdiction to dissolve the bonds of marriage, and no jurisdiction to address custody, time sharing and support of your 13 year old, or any other issue. You would still have to serve her with the divorce petition in Bulgaria. If there is some type of order in place pursuant to which you pay support for your 13 year old, you should get it translated so you know what it says, as it may impact your rights in other respects as well. Consult with an attorney to discuss the specifics of your situation and your options.
