In the Republic of Slovenia, persons who are foreign citizens may also form a legitimate marriage bond. Persons who intend to form a marriage bond register with the registrar authorized for the keeping of the Marriage Register in the settlement where they want to conclude their marriage. In their registration, the persons who intend to form a marriage bond declare that they are concluding their marriage by free will and meeting the conditions for its validity.

In addition to the copy from the Register of Births (issued on the basis of international conventions and certified in accordance with the Act on Verification of Documents in International Traffic), foreign citizens are obliged to accompany their registration also with the following:

• single status certificate
• certificate by the alien's resident country that there are no impediments for the conclusion of marriage
• proof of nationality (certificate or passport)

If the future spouse (foreign citizen) has already been married and the cessation of a previous marriage is not registered in the official registers, the latter is obliged to provide proof on the cessation of an earlier marriage (judgement or a copy form the Register of Deaths).
