If your wife keeps Russian citizenship - in this case it's possible to divorce in Russia. \nRefusing your wife to give you marriage certificate doesn't cause problems: it's possible to get a duplicate. \nYour visit to Russia is not required. You can draw up Power of Attorney and a jurist can act in Russia on your behalf. I explain you more about this Power of Attorney if you would be interested. \n Such proceedings can take from 2 to 6 month. If your wife agree to divorce and signs such agreement - it would take less time. \nPlease answer my following questions: \n1. How does you wife fill about the divorce? Does she agree? \n2. Does you wife keep/have a place of registration in Rostov-on-Don? \n3. Does you wife have Russian citizenship? \n4. Do you have common children? \n5. Do you know her address in Rostov-on-Don? \n6. Do you have any copy of your marriage certificate? \nIt is difficult to me to specify exactly a fee in this case because I don't know yet the amount of work and possible expenses incurred. If your wife agree to divorce I can state my fee and expenses. Otherwise, it is difficult because I don't know yet the number of needed trips to Rostov. \nPlease think about this information. I am looking forward for your decision and answers on my questions.
