Where do I file for divorce, in the state where we were married or the state where I currently reside?

File in Florida

Under the facts you describe, you may file in either State, especially since you are both apparently in agreement upon everything. However, you should consult with an attorney to take into consideration the differing laws that will apply depending upon which State you file in. For example, in FL a parent is generally required to contribute to the support of their children until they reach 18 years of age or graduate from high school, however, in NY it may be until they attain 21 years of age. In FL, a parent cannot generally be ordered to contribute to college costs and expenses of a child, but in NY they may.

If the children are not going to be an issue (custody or child support) you can file in Florida. If there are children's issues you need to file in the state and county where they live.

You can file in Florida as long as you have been a resident for 6 months, and he agrees that you can file here. See an attorney about a potential uncontested divorce. It is much better than trying to do it yourself with a bunch of forms that are quite confusing, and the price is usually reasonable.

You can file where you currently reside. If your spouse has contacts to FL, or if you can serve him within this state, the Court can get personal jurisdiction over him. That is necessary for financial relief. The Court can grant the divorce without it, however. Jurisdiction to decide matters regarding the 9 year old will also be in FL. Jurisdiction over child related matters concerning the 15 year old lies in NY.
