In Adoption of Allison C. (2008) 164 Cal.App.4th 1004, a stepparent adoption case, the mother and child initially left the father after he committed an act of domestic violence against the mother and was incarcerated for more than a year. (Allison C., supra, 164 Cal.App.4th at p. 1007.) "In the summer of 2001 father, by his voluntary act of domestic violence, left Allison in mother's care and custody. Thereafter, he never sought to take parental responsibility for Allison's care, and instead chose to let the child stay with mother. In other words, he was content to leave mother all real parental responsibility for Allison." (Id. at p. 1012.) In Adoption of Allison C. the stepfather was seeking to adopt the child with the mother's consent. The father, who had been in and out of prison for most of the child's life, objected to the adoption. The mother had custody of the child. The family court found that the father had left the child with the mother and had failed to provide support or communicate with the child for a period in excess of one year with the intent to abandon the child. The family court terminated the father's parental rights pursuant to section 7822. (Allison C., at p. 1009.) The father argued the family court's order was not supported by substantial evidence. The appellate court disagreed. As pertinent to this issue, in rather summary fashion, the appellate court concluded that there was substantial evidence to support the conclusion that the father failed to support the child for the statutory period.
