The maternal family prevailed in family and marital relations among the Yukaghirs back in the days.Until the end of the 19th century, the remnants of it remained. One of the remnants is the maternal location of marriage, which means the settlement of the husband in the family of the wife’s parents. The Verkhnekolymsk Yukaghirs did not have a practice of bride money. The groom had to do various housework tasks in the bride’s family for some time. The period preceding marriage was of varying duration. However, with the premarital sexual freedom of girls that existed among the Yukaghirs, the future husband and wife were, in fact, already in a marital relationship even before marriage. The young man had to pass certain tests arranged by the father of the girl in order to get married. Usually, the young man came to live with the bride’s family and became its protector after successfully passing the tests.
After receiving the consent of the bride's parents for marriage, the groom brought his belongings, which consisted only of hunting equipment, to the father-in-law's house and stayed to live there. There were no special ceremonies. According to the descriptions of observers, the son-in-law was usually dependent on the older members of his wife’s family. However, inheritance was given along the paternal line even with the maternal location of marriage. Legend has it, there was a special regime in the past that represented the transitional form from maternal to paternal rights, according to which the eldest son and daughter were considered a part of the mother’s family, and the rest of the children were a part of the father’s family. The Tundra Yukaghirs had a paternal location of marriage. There were ceremonies for marriage proposals and weddings. Although in general, the differences in family and marital relations between the Tundra and Verkhnekolymsk Yukaghirs were not significant.
A custom of avoidance was present in the family, where there was a ban on communication between certain relatives. For example, siblings could not talk to each other, father could not talk with his son's wife, older brother could not talk with his younger brother's wife, etc.
