Hello, civil marriage in Lebanon is not possible simply because of religious matters, i had my civil marriage in Malayasia. If you have a Lebanese background (Father family etc..) i think it would be easier, if not then it depend on the church and Lebanese laws because your marriage would be registered in Lebanon and surely you will need to register it again in your country. In Lebanon the church is chosen upon the male religion, but i strongly recommend that you contact any church before coming to Lebanon, so you have full information from a trusted cleric. About marriage fees, an average Lebanese marriage cost around 30,000 USD (church, cars, restaurant, hotel etc..)
