Certified signatures shall be collected on a signature sheet approved by the Central Election Commission.
(3) The fee for certification of signatures collected in support of a draft law or a draft amendment to the Constitution performed by an orphans’ court or local government institution, is established by taking into account administrative expenses for signature certification which shall not exceed half of the statutory sum required for certifying authenticity of a signature in an orphan’s court.

The owner (administrator) of the Single State and Local Government Service Portal shall not collect payment from signatories.
(5) The Cabinet of Ministers shall set the safety and technical requirements that have to be met if the Single State and Local Government Service Portal (www.latvija.lv) or other online system is used for signature collection, and the Cabinet of Ministers shall appoint an institution that evaluates compliance of the respective online system with these safety and technical requirements. Certification of compliance shall not be carried out for the signature collection system of the Single State and Local Government Service Portal.
