In this digital era, technology has changed many aspects of life. Land purchase agreements in Indonesia, which were previously carried out conventionally, have begun to shift to digital platforms. Digitalization in land purchase agreements offers various opportunities, but this process also has a number of challenges that need to be overcome to ensure that land purchase transactions can be carried out efficiently and safely, providing legal protection to buyers. The formulation of the problem in this study is how the challenges and opportunities of land purchase agreement transactions in the digital era in Indonesia and how legal protection is provided for buyers in digital land purchase transactions in Indonesia. This type of research is library research. Library research is research conducted using references in the form of books, journals, newspapers, magazines or reports of previous research results. Data collection techniques use secondary data, either using primary materials, secondary materials or tertiary materials. Data analysis in this study uses interactive analysis. The results of the study show that the opportunities with the presence of digitalization in land purchase agreement transactions in Indonesia can provide acceleration in accessing information about land, such as location, price, and legal status by prospective sellers and buyers. Transactions can be carried out without having to meet in person. Another opportunity from digitalization in land sale and purchase agreement transactions is the ease of recording and archiving documents. This digitalization also opens up opportunities for the government to eradicate corruption and extortion practices that still often occur in conventional land sale and purchase processes. One of the main challenges faced by buyers is fraud. In digital transactions, fraud can occur through various modes of operation, such as the sale of land with unclear ownership, falsification of documents, or presentation of inaccurate information. Legal protection must be provided to buyers in digital land sale and purchase agreements. The application of digital technology in land sale and purchase agreements must use a blockchain system and e-signatures to verify land ownership. This is done to overcome the problems of duplication and forgery, as well as to increase security and transparency.
