Defensor Santiago publicly advocated for the passage of a divorce law in the Philippines, saying, "Why would you force to be together if they want to kill each other by mere sight?" With respect to her position on divorce, she clarified that it should be restricted on two grounds: "an attempt on the life of the spouse by the other" and "when one spouse is already living with another person, that is adultery or concubinage." In the 2016 Presidential campaign, despite being unable to attend the second debate citing health concerns, she reiterated on Twitter her position on divorce, leaving her as the only presidential candidate to favor its legislation.
