Similar to political parties, there are no restrictions on loans for candidates. In the same time donations and services free of charge from the state, state bodies or self-governing bodies are explicitly prohibited, as are foreign donations
(or at least in as far as the donors are not also resident in the Slovak Republic or are an entity
with its registered seat in the Slovak Republic).
