In S.F. v. Alabama ex rel T.M.,
695 So. 2d 1186 (Ala. Civ. App. 1996) a thirty-seven-year-old man was
found to be liable in paternity, notwithstanding that the court accepted
his testimony that he has no memory of having sex with the plaintiff
after he had been drinking for several hours, and his brother had put
him to bed.
In San Luis Obispo Co. v. Nathaniel J.,
50 Cal. App. 4th 842 (Cal. App. 2d Dist. 1996), a fifteen-year-old boy
who had been seduced by a thirty-four-year-old woman was legally liable
to support the child resulting from his sexual relations with the
mother, notwithstanding that the boy was the adjudicated victim of
unlawful sexual intercourse with a minor. A similar result was reached
in In re Paternity of K.B., 104 P.3d 1132, 1133 (Okla. Civ. App. 2004).
The most surprising case of paternal liability, however, is State of Louisiana v. Frisard,
694 So. 2d 1032 (La. App. 5th Cir. 1997). In this case the father
testified (and the court accepted) that he never had vaginal intercourse
with the plaintiff. Instead the woman inseminated herself from sperm
that she had retained after she performed sex acts on the defendant.
The court found the man liable for child support.”
