Bukalapak is one of the leading online marketplaces in Indonesia which provides a
means of buying and selling for pelapak (sellers) and buyers. Bukalapak has
provided User Rules which are standard clauses.Legal issues in this thesis are, the
application of the principle of freedom of contract and the principle of balance of
interests in buying and selling activities through Bukalapak and the position of the
parties in carrying out buying and selling activities through Bukalapak. The method
used in writing this thesis is a normative legal. After that, analysis with qualitative
methods was carried out. The results of this thesis study show that the application
of the principle of freedom of contract is not fully implemented and the principle of
balance of interests is not maximally achieved in buying and selling activities
through Bukalapak, because there is a standard clause. Bukalapak's position is
stronger than the pelapak and buyers who have a weaker position because only their
interests are realized through User Rules / standard clauses.
