A child includes a stepchild or an adopted child. Previously, stepchild adoption as well limited co-guardianship rights for non-biological parents was permitted. Similar words recorded later in Old English include "stepbairn", "stepchild" and "stepfather". NYC saw the Putnam Division as a dispensable stepchild. He has four biological children and one surviving stepchild. He married and divorced three times; he had one stepchild as a result. Stepchild adoption has been legal since 2009. In the United States, the most common form of adoption is adopting a stepchild. In late 2018 San Marino parliament voted to legalise civil unions with stepchild adoption rights. Some MPs opposed stepchild adoption, while others demanded same-sex marriage. However, they can only adopt the biological child of their same-sex partner (so-called stepchild adoptions). There are no explicit prohibitions on adoption by same-sex couples or on stepchild adoptions. As of 2019, joint and stepchild adoption by same-sex couples remain illegal. Stepchild adoption has been allowed for registered partners since 2002. Same-sex adoption was legalized alongside same-sex marriage in 2001, which includes joint and stepchild adoption.
