혼인 종료 후 300일 이내에 출생한 자를 법률상 예외 없이 부의 친생자로 추정하되, 이에 어긋나는 경우라면, 엄격한 친생부인의 소를 통하여만 해결하도록 하는 것이 합리적이었다.
A person who was born within 300 days after the end of the marriage is assumed to be the father's birth child, without any exceptions under the law, but if it was against this, it was reasonable to settle it only through the strict lawsuit of the birth denial.
