[Skripsi ini membahas erosinya doktrin consideration di common law. Walaupun
consideration adalah salah satu syarat sah perjanjian di common law, consideration
bukanlah suatu syarat sah perjanjian di civil law. Consideration dibandingkan dengan
hukum Indonesia sebagai representasi dari sistem civil law. Konsep consideration itu
sendiri di common law telah ditemukan sebagai problematik dan tidak tetap. Isu
utama dari consideration sebagai syarat sah perjanjian adalah consideration
mencegah pelaksanaan janji tanpanya. Sebagai cara menghindari permasalahan ini,
hakim-hakim di common law mengupayakan berbagai pengecualian dan alternatif dari
consideration. Seiring dengan peningkatan penggunaan pengecualian dan alternatif
untuk consideration, erosi terjadi. Dalam pengertian ini hukum perjanjian di common
law menjadi mirip dengan civil law, yang tidak pernah menyaratkan consideration.
Penelitian ini menunjukan bahwa ketika menghadapi pilihan hukum antara civil dan
common law seseorang harus menyadari perbedaan persyaratan contract., This research discusses the eroding doctrine of consideration in the common law.
Although consideration is one of the requirements of a valid contract in the common
law, it is not required in civil law contracts. Therefore the concept of consideration in
common law is compared to Indonesian law, which is a representative of the civil law
system. In fact, the very concept of consideration in the common law has been found
to be problematic and non-rigid. The main issue with consideration, as a requirement
of contract, is that it halts the enforcement of promises lacking consideration. As a
way around this problem, judges in common law often resort to various exemptions
and alternatives to consideration. Along with the increased usage of exemptions and
alternatives to consideration, the doctrine of consideration has eroded. In this sense
contract law in common law has become somewhat similar to that of civil law, which
never required consideration for contracts in the first place. This research suggest that
when facing a choice of legal system between common and civil law, one must be
aware of the differences in the contractual requirements.]
