Based on analysis of the cases sent to the Bureau of Investigation by the courts, the scenarios where paternity testing is required include: someone conceived out of wedlock making inheritance claims; grandparents wishing to claim guardianship of a child from the unwed mother when the father died before the child was born; mainland Chinese families seeking relatives in Taiwan; and applications for immigration.
根據調查局受理法院委託的鑑定案件分析，需要親子鑑定的情況包括：非婚生子女爭搶遺產、祖父母在兒子過世後，想認領未婚媳婦的遺腹子、中國大陸親屬來台依親，或是辦理海外移民等等。
