LGBT adoption in the United States
The legal status of LGBT adoption in the United States varies by jurisdiction. States and other jurisdictions may restrict adoption by sexual orientation or marital status. In some states, since adoptions are handled by local courts, practices may vary within a given jurisdiction. A same-sex couple can adopt in some states. More states permit adoption by an individual who is gay or lesbian.
About half of all states permit second-parent adoptions by the unmarried partner of an existing legal parent, while in a handful of states courts have ruled these adoptions not permissible under state laws. This leaves parents in many states legally unrecognized or severely disadvantaged in court fights with ex-spouses, ex-partners or other relatives.
Same-sex marriage can remove legal obstacles to the adoption of children by lesbian, gay, bisexual and transgender (LGBT) persons. Adoption can take the form of a joint adoption by a same-sex couple (second parent adoption) or adoption by one member of a same-sex couple of the other's biological child (stepparent adoption). The second parent adoption process by a state-recognized spouse or partner is generally more streamlined and less expensive than stepparent adoption, though even the former is not as simple for same-sex couples as for different-sex couples unless their state recognizes same-sex marriages.
As of 2012, approximately two million children in the United States were being raised by LGBT parents and unable to establish a legal relationship with both their parents. According to the Williams Institute, as of 2009 "an estimated 20,000 same-sex couples are raising nearly 30,000 adopted children."
Professional assessments 
A consensus has developed among the medical, psychological, and social welfare communities that children raised by gay and lesbian parents are just as likely to be well-adjusted as those raised by heterosexual parents. The research supporting this conclusion is accepted beyond serious debate in the field of developmental psychology. Based on the robust nature of the evidence available in the field, the Third District Court of Appeal of the State of Florida was satisfied in 2010 that the issue is so far beyond dispute that it would be irrational to hold otherwise; the best interests of children are not preserved by prohibiting homosexual adoption.
Public opinion 
A 2006 poll by the Pew Research Center found the United States public closely divided on gay adoption, while a 2007 poll by CNN and Opinion Research Corp. said 57% of respondents felt gays should have the right to adopt and 40% said they should not.
On July 29, 1999, U.S. Representative Steve Largent introduced amendment 356 (H.Amdt. 356) to the District of Columbia Appropriations Act, 2000 (H.R. 2587) that would have banned joint adoption between individuals who are not related by blood or marriage in Washington, D.C. The amendment failed with 213 votes in favor and 215 opposed.
On May 10, 2012, Republican presidential candidate Mitt Romney told an interviewer: "And if two people of the same gender want to live together, want to have a loving relationship, or even to adopt a child -- in my state individuals of the same sex were able to adopt children. In my view, that's something that people have a right to do." Asked the next day to reconcile that with his opposition to same-sex marriage, he said: "Well actually I think all states but one allow gay adoption, so that's a position which has been decided by most of the state legislators, including the one in my state some time ago. So I simply acknowledge the fact that gay adoption is legal in all states but one."
Full joint adoption by same-sex couples is currently legal in the following jurisdictions: Rhode Island (1993), District of Columbia (1995), New Jersey (1998), New York (2002), California (2003), Indiana (2006), Maine (2007), Florida (2010), Arkansas (2011), Connecticut, Illinois, Massachusetts, Oregon, Vermont, New Hampshire, Washington, Hawaii, Iowa, Nevada, Delaware, Maryland, Colorado, Minnesota, and Guam.
Alabama. On October 12, 2012, a unanimous Alabama Court of Civil Appeals turned down the request of a woman to adopt her same-sex spouse's child. The women had been married in California. The court held that Alabama law did not recognize the women as spouses.
Arkansas. On November 4, 2008, Arkansas voters approved Act 1, a measure to ban anyone "co-habitating outside of a valid marriage" from being foster parents or adopting children. Although the law could apply to heterosexual couples, it was believed to have been written to target gay couples due to the fact that same-sex marriage is prohibited in that state, thereby making an adoption impossible. Single gay men and lesbians were still allowed to adopt in Arkansas. The law was overturned on April 16, 2010 by state judge Chris Piazza. The Arkansas Supreme Court in Howard v. Arkansas upheld the lower court's decision on April 7, 2011.
Florida. In Florida, a 1977 law prohibited adoption by homosexuals following the anti-gay Save Our Children campaign led by Anita Bryant. In November 2008, a state circuit court struck down the law in In re: Gill, a case involving a gay male couple raising two foster children placed with them in 2004 by state child welfare workers. On appeal, on September 22, 2010, Florida's Third District Court of Appeals unanimously upheld the decision of the lower court. The state did not appeal.
Kansas. In November 2012, the Kansas Court of Appeals ruled in the case In the Matter of the Adoption of I. M. that a single person who is not a biological parent of a child cannot petition to adopt that child without terminating the other parent's parental rights. Since Kansas does not recognize same-sex marriages, this ruling effectively prevents same-sex couples from second-parent adoption in Kansas. However, the Kansas Supreme Court ruled on February 22, 2013, in Frazier v. Goudschaal that a partner of a biological parent is entitled to parental rights.
Two Michigan lesbians, who are raising three children adopted by only one of them, filed a lawsuit in federal court in January 2012 seeking to have the state's ban on adoption by same-sex couples overturned. and in September amended that suit to challenge the state's ban on same-sex marriage as well.
New York. An October 2012 court ruling in a custody dispute between two women in a same-sex relationship awarded custody to the adoptive parent rather than the biological mother.
Utah. A single person can adopt in Utah, except that by Utah law "a person who is cohabiting in a relationship that is not a legally valid and binding marriage." A single person not co-habiting can adopt.
Recognition of adoption by other states 
In August 2007, the Tenth Circuit Court of Appeals in the case of Finstuen v. Crutcher ordered Oklahoma to issue a revised birth certificate showing both adoptive parents to a child born in Oklahoma who had been adopted by a same-sex couple married elsewhere. It held that an Oklahoma statute that rejects certain out-of-state adoption decrees violates the Full Faith and Credit Clause of the U.S. Constitution. By contrast, Louisiana in Adar v. Smith successfully defended in federal court its refusal to amend the birth certificate of a child born in Louisiana and adopted in New York by a same-sex married couple who sought to have a new certificate issued with their names as parents as is standard practice for Louisiana-born children adopted by opposite-sex married couples. The Supreme Court refused to hear the case on appeal.
