SUMMARY
Notary's concept as Registration Authority has been facilitated by Indonesian law, for example Law Number 2 Year 2014 About Amendment to Law Number 30 Year 2004 Concerning Notary Public, which explains that "other authorities regulated in legislation", the authority to certify electronic transactions (Cyber notary), make a Deed of pledge of waqf, and mortgage of aircraft. In addition to Law Number 2 Year 2014 on Amendment to Law Number 30 of 2004 concerning Notary Public, Notary's role as Registration Authority is also described in Government Regulation Number 82 Year 2012 Concerning the Implementation of Electronic Transaction System and Transaction, especially in the explanation Article 59 Paragraph (5) explaining that the Ministerial Regulation contains, among other things, arrangements on the procedure of applying for electronic certification which can be submitted through a notary. In contrast to the notary role concept as the Registration Authority, the notary role concept as a subordinate certification authority is not possible because of various obstacles.
