The legal status of same-sex marriage may have implications for the marriages of couples in which one or both parties are [[transgender]], depending on how sex is defined within a jurisdiction. Transgender and [[intersex]] individuals may be prohibited from marrying partners of the "opposite" sex or permitted to marry partners of the "same" sex due to legal distinctions.{{citation needed|date=February 2021}} In any legal jurisdiction where marriages are defined without distinction of a requirement of a male and female, these complications do not occur. In addition, some legal jurisdictions recognize a legal and official change of gender, which would allow a transgender male or female to be legally married in accordance with an adopted gender identity.<ref>Bockting, Walter, Autumn Benner, and Eli Coleman.

In the United Kingdom, the ''[[Gender Recognition Act 2004]]'' allows a person who has lived in their chosen gender for at least two years to receive a gender recognition certificate officially recognizing their new gender. Because in the United Kingdom marriages were until recently only for mixed-sex couples and civil partnerships are only for same-sex couples, a person had to dissolve their civil partnership before obtaining a gender recognition certificate{{citation needed|date=February 2020}}, and the same was formerly true for marriages in England and Wales, and still is in other territories. Such people are then free to enter or re-enter civil partnerships or marriages in accordance with their newly recognized gender identity. In Austria, a similar provision requiring transsexual people to divorce before having their [[legal sex]] marker corrected was found to be unconstitutional in 2006.<ref>{{Cite web |date=5 July 2006 |title=Austria gets first same-sex marriage |url=http://www.365gay.com/Newscon06/07/070506austria.htm |archive-url=https://web.archive.org/web/20071017161302/http://365gay.com/Newscon06/07/070506austria.htm |archive-date=17 October 2007 |access-date=20 July 2008 |publisher=365gay.com}}</ref> In Quebec, prior to the legalization of same-sex marriage, only unmarried people could apply for legal change of gender. With the advent of same-sex marriage, this restriction was dropped. A similar provision including sterilization also existed in Sweden, but was phased out in 2013.<ref>{{Cite web |date=11 January 2013 |title=Sweden ends forced sterilization of trans |url=http://www.gaystarnews.com/article/sweden-ends-forced-sterilization-trans110113 |url-status=live |archive-url=https://web.archive.org/web/20180612234631/https://www.gaystarnews.com/article/sweden-ends-forced-sterilization-trans110113/ |archive-date=12 June 2018 |access-date=10 October 2017 |website=gaystarnews.com}}</ref> In the United States, transgender and intersex marriages was subject to legal complications.<ref>{{Cite journal |last=Deborah |first=Anthony |date=Spring 2012 |title=CAUGHT IN THE MIDDLE: TRANSSEXUAL MARRIAGE AND THE DISCONNECT BETWEEN SEX AND LEGAL SEX. |journal=Texas Journal of Women & the Law |volume=21 |issue=2}}</ref> As definitions and enforcement of marriage are defined by the states, these complications vary from state to state,<ref>{{Cite news |last=Schwartz |first=John |date=18 September 2009 |title=U.S. Defends Marriage Law |work=The New York Times |url=https://www.nytimes.com/2009/09/19/us/19brfs-USDEFENDSMAR_BRF.html |url-status=live |access-date=29 September 2009 |archive-url=https://web.archive.org/web/20140714172436/http://www.nytimes.com/2009/09/19/us/19brfs-USDEFENDSMAR_BRF.html |archive-date=14 July 2014}}</ref> as some of them prohibit legal changes of gender.<ref>{{Cite web |title=Movement Advancement Project {{!}} Equality Maps |url=http://www.lgbtmap.org/equality-maps |url-status=live |archive-url=https://web.archive.org/web/20190422164047/http://www.lgbtmap.org/equality-maps |archive-date=22 April 2019 |access-date=2019-04-19 |website=www.lgbtmap.org |language=en}}</ref>
