In the sale and purchase transaction, the delivery of objects and payments are made based
on the will of the parties contained in the Sale and Purchase Deed made by the Land Deed Making
Officer (hereinafter referred to as PPAT) (Febriyana, 2021). PPAT in carrying out its duties and
functions is based on an applicable norm, namely Government Regulation Number 37 of 1998 as
amended by Government Regulation Number 24 of 2016 concerning Regulations on Land Deed
Making Officials. In activities to transfer land rights, it must be done in front of PPAT by making a
deed of engagement based on Article 1 of Government Regulation Number 37 of 1998 as
amended by Government Regulation Number 24 of 2016 (Hamonangan et al., 2021).
Based on the Basic Agrarian Law Number 5 of 1960 (hereinafter referred to as UUPA) and
Government Regulation Number 24 of 1997 concerning Land Registration (hereinafter referred
to as PP 24/1997), it is emphasized that the sale and purchase of land must be carried out with a
deed made by and before PPAT (Lambonan, 2018). The deed made by PPAT proves that there is
a legal act of transfer of land rights and serves to provide legal certainty over land and become
one of the sources for data maintenance.
The sale and purchase agreement has essential elements, namely the existence of goods
and prices (Wang et al., 2024). This element is an absolute element that must be present in the
act of buying and selling and in carrying it out must be carried out in light and cash (Damayanti,
2020). Cash in the sense that payment for the object to be transferred must be carried out
immediately as well as the delivery of the purchased object must be done in a transparent
manner, so as to avoid fraud.
The nature of light and cash in Indonesian Land Law comes from Customary Law, which is
the original law of the indigenous group (Arliman, 2018). Customary Law is used in the Law of
Indonesian Land because in the UUPA there are still incomplete rules, so to avoid legal voids,
Customary Law is used to complete it, this is stated in Article 58 of the UUPA, namely:
"As long as the regulations for the implementation of this Law have not been formed, the
regulations, both written and unwritten regarding the earth and water and the natural
resources contained therein and the rights to land, which existed at the time of the entry
into force of this Law, shall remain in force, as long as they do not conflict with the spirit of
the provisions of this Law and are interpreted accordingly."
This means that the sale and purchase of land rights in Indonesia adheres to the nature of
customary law, namely the nature of light and cash. According to (Salim, n.d.) o, light is defined
as a legal act carried out in front of an authorized public official, namely PPAT, while cash is
interpreted as the agreed purchase and sale price that must be paid in cash/in full. If the buyer's
obligation has not been fulfilled to pay off the payment, then the buying and selling process
cannot be carried out (Zhou, 2014).
In practice, buying and selling can be carried out on tough terms, it can be called a
conditional agreement (voorwarrdelijke). A conditional covenant is an engagement that is hung
on an event in the future, still not necessarily going to or happening. This can hinder the act of
