People in Serbia are able to form and join associations. The constitution guarantees the right to freedom of association and the registration and operation of CSOs is regulated by the Law on Associations and the Law on Endowments and Foundations. The registration process is simple and clear and there are no restrictions on the receipt of foreign funding. Some human rights defenders and their organisations have been subjected to continuous smear campaigns, defamation, attacks and harassment. LGTBI activists and women human rights defenders are especially vulnerable to attacks. During a six month period, the Belgrade Pride Organizing Committee documented between 30 and 50 cases of online threats against activists.
