A Dictionary of Law
The direct line; the vertical line. In computing degrees of kindred and the succession to estates, this term denotes the direct line of ascendants and descendants. Where a person springs from another immediately, or mediately through a third person, they are said to be in the direct line, (tinea recta,) and are called “ascendants” und “descendants.”
