I am a Budhist, married to a Moslem,whom I married in a civil wedding overseas.Can I file for divorce in Israel?

Yes, at the family court.The vice-president will have to decide which court has jurisdiction to dissolve your marriage, but as Buddhism is not a recognised faith in Israel, whereas Islam is, he will decide that the family court has juisdiction over your divorce. If your husband agrees to divorce, the process will be smooth as mutual consent is sufficient grounds to end the marriage. Otherwise, you will have to prove you have divorce grounds, by means of presenting a legal opinion by an expert on the laws of marriage and divorce in the country where you married.
