My partner and I are a same-sex couple. Can I adopt his child?
Only a few states allow this, so be sure to check with your own state’s laws. In California, for instance, registered domestic partners may use the stepparent adoption procedures to adopt their partners’ children. Since Massachusetts recognizes same-sex marriage, same-sex spouses can adopt using the stepparent adoption procedures just like opposite-sex married couples can. In states that do not recognize same-sex domestic partnerships or same-sex marriage, however, a member of a same-sex couple most likely cannot adopt their partner’s child.
