Duval first married television director Mário Pomponet Júnior. Her second husband was
Daniel Filho, with the marriage taking place in
Las Vegas. They had a daughter, actress Carla Daniel, in 1965. Her third husband was an advertising producer and filmmaker, Paulo Sérgio Garcia Alcântara, who was unemployed when she met him and for whom she found a job through her contacts. He was 16 years younger than Duval and she was constantly the victim of verbal abuse by him, calling her old and saying that he wanted younger women. In 1980, in a moment of anger, she responded to the insults and humiliations and shot her husband three times in their house in
Jardim Botânico, Rio de Janeiro, killing him. For this she was initially sentenced to 18 years in prison, with her husband's family arguing that the crime was premeditated. She was later retried and sentenced to six years in prison, by which time it was almost time for her release. After release from prison, she decided not to return to acting, preferring to remain out of the limelight. She wrote an autobiography, together with
Luiz Carlos Maciel and Maria Luiza Ocampo, which was released in 2002, entitled
Em Busca da Luz - Memórias de Dorinha Duval (In search of light – Memories of Dorinha Duval). In this she narrated the experience of being raped at the age of fifteen, having an abortion and prostituting herself. Duval also reveals that she attempted suicide after the separation from
Daniel Filho and explains why she killed her third husband. In 2006, she appeared in the final episode of the TV Globo telenovela
Belíssima, which paid tribute to some famous stars. In 2018, she returned to television in an event organized with veteran actors. She remained part of Globo's retired team; a group of artists still on contract but no longer working. Among other things, this provides medical insurance. ==Death==
