A paternity test has taken a surprising turn in a case brought by a mother against the alleged father of her children. The mother had twins, but the sisters both appear to have different fathers. This was revealed by a DNA-based paternity test, which was used to support evidence in a maintenance lawsuit.

Two fathers for the twins

The twins were born in 2013. The children’s mother filed a lawsuit against her ex-partner, demanding alimony for the twins. A paternity test was performed to verify that the man was indeed the father of the children. That turned out to be only partly the case, he was related to one of the two children. The other half of the twins had a different father.

Rare, but possible

It turns out to be a rare case where twins are born with two different fathers. According to experts, this is indeed possible, although it is rare. A woman can have intercourse with two different men within a single menstrual cycle, each fertilizing an egg. According to experts, this occurs in 1 in 13,000 parenting cases, it is the first time that a paternity test has actually shown this.

Similar case twice before

According to the court, a similar case has occurred twice before. The mother later admitted that she did indeed share the bed with two different men during the same period. Based on the results of the paternity test, the alleged father must pay maintenance for one of the two children, for the rest of the maintenance the mother will have to pay the other father.
