||The overwhelming majority of the more than five and a half million Syrians have fled to neighboring countries in the Middle East without their civil documents. Particularly in a refugee context, it is crucial for the standard of living for Syrian refugees and eventual return to Syria to be adequately documented. Complex civil registration systems in the host countries, however, often prevent Syrian refugees from obtaining civil documentation, thereby expanding the problem of the lack and loss of civil documentation of Syrian refugees. This thesis examines the different civil registration systems and their consequences for Syrian refugees in Jordan, Turkey, and Lebanon through an in-depth analysis focusing on legal status, marriage and birth registration. This thesis argues that the difference in implemented civil registration systems is determined by each host country’s social, political, and economic situation before and during the Syrian refugee influx and the extent to which the Syrian refugees have impacted the country, positively and negatively. In Turkey, the government has adopted a temporary protection regime, which includes refugee-sensitive civil registration systems. However, in Lebanon and to a lesser extent Jordan, Syrian refugees are still facing many challenges trying to obtain civil documentation due to the complex civil registration systems. As the eight years of hosting refugees has turned out more harmful than beneficial for the host countries, discussions on the return of Syrian refugees has increasingly become louder. However, a lot of change is still required to ensure that Syrian refugees are adequately documented.
