Can a lawyer in the US fight a divorce filed in another country?

You need a lawyer licensed to practice in the jurisdiction in which any lawsuit is filed to represent you.  The same goes for divorce suits.  However, if that court has no personal jurisdiction over you, such as that you have not lived there, have not been served with papers while in that country, or it is not the last place of marital residence, then the courts in the United States may refuse to recognize that divorce and you can file your own divorce here to have any issues of property and support decided by a U.S. court.  The U.S. courts may also rehear your divorce if they determine that the foreign court did not provide you with adequate due process.  This answer is given in accordance with the laws of Virginia and may not be applicable in any other state.  It should not be construed as legal advice, as that would require a more thorough analysis of all of the facts involved in a specific case.  If you need further information or assistance, please feel free to contact my office for a consultation. Case results depend upon a variety of factors unique to each case. Case results do not guarantee or predict a similar result in any future case.
