Several generations of close relatives can marry

HOME > Knowledge

China's law allows the marriage of close relatives beyond three generations, because with the continuous development of medical technology, there are certain changes in the overlap of genes beyond three generations, which will not affect the health of the next generation.

Marriage of close relatives within one or three generations is prohibited

Consanguineous marriage is an act of marriage registration by consanguineous relatives in the immediate line or within three generations.

Direct blood relatives refer to people with whom they are directly related by blood or marriage, such as spouses, children, parents, etc.

Collateral blood relatives refer to those other than immediate family members who share the same blood with them and their spouses, such as brothers, sisters and spouses. Chinese law clearly stipulates that within three generations of direct or collateral blood relatives prohibited marriage.

Marriage beyond the second or third generation is allowed

With the continuous development of modern medical technology and the change of human genes, the provisions of Chinese law on marriage between close relatives have changed from five generations or less to three generations or less. Therefore, marriage of first Cousins beyond three generations is permissible and allowed by law.

However, the risk of marriage between close relatives still exists, and the offspring born may have genetic diseases, etc., so it is not recommended to marry close relatives.
