Definitions of Relationships
Establishing paternity means identifying a man as the biological
father of a child. Paternity testing is necessary in many
situations; including, custody, child support, adoption,
immigration, estate purposes and many other legal reasons.
Establishing maternity means identifying a woman as the
biological mother of a child. In most situations, it is evident who
the mother is. However, in cases of adoption, immigration and
various legal situations, maternity testing may be necessary.
Relationship testing is establishing a biological relationship
to any family member of the alleged father or mother. Typically,
relationship testing is performed when the alleged father or mother
is unavailable and includes the following:
Grandparentage - Determining whether or not the
alleged father or mother's parents are the biological grandparents
of the child.
Avuncular - Determining whether or not a
sibling of the alleged father or mother is the biological aunt or
uncle of the child.
Siblingship - Determining whether or not one or
more children share one or both of the same biological parents.
