Divorce attorney, after an uncontested divorce from my wife, is it possible to marry my sister-in-law?

Hello. This is a divorce attorney at Daeryun Law LLC.

According to the Civil Act, even if you have had an uncontested divorce from your wife, you cannot marry your sister-in-law, who is a member of your wife's family.

This is because, legally, marriage with a blood relative within the sixth degree of the spouse is prohibited, and a sister-in-law, as a direct family member of the wife, falls within blood relatives of the sixth degree.

In other words, even if you have had an uncontested divorce, marriage with a sister-in-law who was formerly a relative by marriage is prohibited under Article 809, Paragraph 2 of the Civil Act.

If, in violation of this, you marry your sister-in-law, not only the parties but also a lineal ascendant or a collateral blood relative within the fourth degree may petition the court to annul the marriage.

If you need legal procedures or a consultation related to this, it is advisable to consult a divorce attorney with extensive experience.

I will also share the relevant law, so please refer to it.
