"d. Voter Registration

Until the unified voter register becomes operational from 1 January 2026, voter registration remains decentralized and passive. Citizens are automatically included in the voter lists based on their permanent residence, with municipal authorities responsible for maintaining and updating the registers using data from the population register maintained by the MoI. Citizens residing abroad must actively register with the special voters list maintained by the embassy or consulate closest to their place of long-term residence. Voters may apply for an Absentee Voting Certificate from the municipality of their permanent residence, enabling them to vote at a different polling station or a diplomatic mission abroad."
