The Bulgarian Constitution guarantees freedom of association, and the Law on Legal Entities with Nonprofit Purposes (NGO Law) provides that both Bulgarian and foreign legal entities and individuals with legal capacity can found a nongovernmental organization (NGO). (Only minors under 18 years of age and persons under guardianship cannot found an NGO.) The traditional forms of POs are associations and foundations. There is no minimum capital requirement to establish either of the two forms of organization (although foundations are required to provide some capital to pursue their objectives).
