The definition of adultery for the purpose of granting a divorce or barring alimony is illicit intercourse between two persons, at least one of whom is married to someone other than the sexual partner.
Explicit extra-marital sexual activity constitutes adultery regardless of whether it is of a homosexual or heterosexual character.
Adultery may be proven by circumstantial evidence showing inclination and opportunity to commit adultery.
Proof of adultery must be clear and positive. The infidelity must be established by a clear preponderance of the evidence, sufficiently definite to identify the time and place of the offense.

Condonation may be nullified by subsequent acts of adultery, which revive the formerly acts of adultery. Reconciliation (resumption of marital cohabitation) is another form of condonation and it is a defense to the charge of adultery.
