The arrangement for the detention of the certificate by the Notary as a guarantee for the repayment of the Notary's Honorariun is still unclear. This thesis discusses the Detention of Ownership Certificates by a Notary as a Guarantee of Payment of the Notary's Honorarium for Decision Number 37 / Pdt / 2020 / Pt Mks. The Law on Notary Position still does not provide a clear meaning regarding these provisions and only establishes the maximum amount of honorarium that must be received by the Notary Public, in the absence of such certainty, the problem of paying this honorarium often occurs. As a result, the Notary/PPAT is not guilty of making a mistake against the client's certificate against the law. The guarantee of certificates to Notaries / PPAT has not been regulated explicitly and clearly regarding the authority / obligations and prohibitions of Notaries / PPATs from receiving guarantees related to the process of paying off the Notary's Honorarium. This study uses a normative juridical research method with a prescriptive type of research. The result of this research is that notaries who practice to hold certificates are based on the principle of freedom of contract, and provisions regarding guarantees by carrying out objective novation. Notaries and clients can act in good faith by entering into a written agreement before making a deed related to payment of honorarium, and guarantees on land can be done by registering mortgage rights with the National Defense Agency
