With the rapid change of today`s society and the development of modern science, legal matters are becoming ever more diverse and complicated. This means that specific disputes in actual life in the society cannot meet reasonable and valid solutions through application of conventional legal principles alone. Artificial reproduction remains a hot potato and foreign legislations are accelerating to catch up with its development. Still, they aren`t quite catching up with the speed of its development, and more fundamentally, people have come to harbor fundamental questions on whether legislation suited to the speed of the development is appropriate. Specifically, now that humankind has satisfied its needs for food and clothes to some extent, artificial reproduction openly fulfills the instinctive desire for offspring. Foreign legal systems have achieved various legislations in order to address such issues. In contrast, the Korean legal system has only regulatory laws such as Bioethics and Safety Act, designed to promote the bioethics and safety involved in the development of bioengineering technology. The country`s legal system has not created any explicit laws that can respond to such civil code issues and has instead made an attempt to legislate on the full gamut of artificial reproduction. Then, civil code issues and disputes related to artificial reproduction cannot but be regulated through civil law interpretation. But, such interpretation must have limitations, which are evidently due to flaws in the civil code that never foresaw artificial reproduction. Mindful that modern technology for artificial reproduction has thrown doubt on the previously taken-for-granted belief that a parents-child relationship has to be determined by blood kinship, I suggest that establishing a father-child relationship further requires a review of multiple perspectives such as bioethics, the welfare of the child, the perception of related persons that constitute own child or family relation, and the thoughts of the general public, and clearly make it necessary to upgrade the intention to become a father, that is, the volitional element involved to a requirement that finalizes a father-child relationship.
