Can one marry if their maternal grandmother and paternal grandmother of the partner share the same family name?

Section 18, Article 3 of the 2014 Law on Marriage and Family stipulates:

Persons who are related by blood within three generations are those who share a common origin, including: parents as the first generation; siblings by the same parents, by the same father but different mother, or by the same mother but different father as the second generation; cousins who are children of uncles, aunts, and other similar relations as the third generation.

And Point d, Section 2, Article 5 of the 2014 Law on Marriage and Family explains as follows:

Marriage or cohabitation as husband and wife between those who share direct blood lineage; between those who are related within three generations; between adoptive parents and adopted children; between former adoptive parents and adopted children, father-in-law and daughter-in-law, mother-in-law and son-in-law, stepfather and stepchild of the wife, stepmother and stepchild of the husband;

In your case, the relationship between your grandmother and your boyfriend's grandmother has not been clearly defined, only indicating that they share a surname. However, according to regulations regarding persons related within three generations, it can be determined that you and the other person do not fall within this category. Therefore, you and your boyfriend are fully entitled to get married if you meet the other conditions specified by law in this act.

Sincerely!
