My question involves a marriage in the state of:Florida

My wife and I recently got divorced in a foreign country (got married in the same country ~20 years ago), with all the foreign property being divided equally, according to the country's laws. We both have two citizenships (US and the other country). From what I understand, we don't need to file for divorce in the US - is that so?

Assuming the answer to the question above is yes, what type of agreement we need to make to divide our US based assets (mostly cars and bank accounts). The family lawyer I consulted with says we can't do a standard Florida asset separation agreement because, technically, we are already divorced. I want to do it cleanly so that she can't go after me in 3 years. In general, we can agree on how to split everything, I just want to do in a way that can't be disputed later. Thanks in advance!
