Relatives are disqualified as witnesses according to Scriptural Law, as implied by Deuteronomy 24:16: "Fathers shall not die because of sons." According to the Oral Tradition, the verse is interpreted as meaning that included in this prohibition is that fathers should not die because of the testimony of sons, nor should sons die because of the testimony of fathers. Similar laws apply with regard to other relatives.According to Scriptural Law, only paternal relatives are disqualified - i.e., a father with his sons and grandsons, paternal brothers with each other, and the sons of paternal brothers with each other. Needless to say the uncles may not testify with their brother's sons. Maternal relatives or people related by marriage are disqualified only by Rabbinic decree.

Converts are not considered as relatives. Even two twin brothers who convert may testify on each others behalf. For a convert is considered as a newborn child.הלכה ג

Brothers - whether maternal brothers or paternal - are considered as one degree removed. Their sons are considered as two degrees removed. And their grandsons are three degrees removed.הלכה ד

A person who is three degrees removed may testify on behalf of one who is one degree removed. Needless to say, one who is three degrees removed may testify on behalf of one who is two degrees removed. But two who are both two degrees removed, and needless to say, one who is two degrees removed and one who is one degree removed are both disqualified from testifying.הלכה ה

A father and his son are considered as one degree removed. Therefore a father is disqualified from testifying with his grandson. With his great-grandson, i.e., the fourth generation, he is acceptable, for he is of the first degree and the great-grandson, three degrees, removed. Similar laws apply with regard to women relatives.What is implied? Two sisters or a brother and a sister - whether paternally or maternally related - are considered as one degree removed. Their children whether male or female are considered as two degrees removed and their grandchildren - including the sons of their sons and the daughters of their daughters - are considered as three degrees removed. Just as we count the degrees descendants are removed for males - one degree, two degrees, and three degrees - so, too, we count the degrees for females.

Whenever a person is disqualified from testifying on behalf of a woman, he is also disqualified from testifying on behalf of her husband, for a husband is considered like his wife. Conversely, whenever a person is disqualified from testifying on behalf of a man, he is also disqualified from testifying on behalf of his wife, for a wife is considered like her husband.הלכה ז

Whenever a witness is disqualified from testifying on behalf of a colleague because he is married to the witness' relative, the witness may testify on behalf of the other relatives of that colleague, e.g., his son and his brother. Similarly, whenever a witness is disqualified from testifying on behalf of a woman because she is married to the witness' relative, the witness may testify on behalf of her other relatives, e.g., her son and her brother.הלכה יא

A man and his wife are considered as being removed by one degree. Hence a husband may not testify on behalf of his wife's son, the wife of his wife's son, his wife's daughter, the husband of his wife's daughter, his wife's father, his wife's mother, the husband of his wife's mother, nor the wife of his wife's father.הלכה יד

When a person has consecrated a woman, although the marriage bond has not been consummated, with regard to testimony, it is as if she is fully married.To whom does the above apply? To the woman he consecrated herself; he may not testify on her behalf. If, however, he testifies on behalf of the relatives of the woman he consecrated, e.g., her sister's husband, her son or daughter, or the like, we do not disqualify him until he marries her.

The Torah did not disqualify the testimony of relatives because we assume that they love each other, for a relative may not testify neither on his relative's behalf or against his interests. Instead, this is a Scriptural decree.For this reason people who love each other or who hate each other are acceptable as witnesses even though they are not acceptable as judges. For the Scriptural decree disqualifies only relatives as witnesses.
