Transgender and Intersex Persons

See also: Transsexualism, Legal aspects of transsexualism, and Gender identity

When sex is defined legally, it may be defined by any one of several criteria: the XY sex-determination system, the type of gonads, the type of external sexual features, or the person's social identification. Consequently, both transsexuals and intersexed individuals may be legally categorized into confusing gray areas, and could be prohibited from marrying partners of the "opposite" sex or permitted to marry partners of the "same" sex due to legal distinctions. This could result in long-term marriages, as well as recent same-sex marriages, being overturned.

The problems of defining gender by the existence/non-existence of gonads or certain sexual features is complicated by the existence of surgical methods to alter these features. Estimates run as high as 1 percent of live births exhibiting some degree of sexual ambiguity, and between 0.1% and 0.2% of live births being ambiguous enough to become the subject of specialist medical attention, including sometimes involuntary surgery to address their sexual ambiguity.

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 transsexual to be legally married in accordance with an adopted gender identity.

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 UK marriages are for mixed-sex couples and civil partnerships are for same-sex couples, a person must dissolve his/her marriage or civil partnership before obtaining a gender recognition certificate. Such persons 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 persons to divorce before having their legal sex marker corrected was found to be unconstitutional in 2006.

In Quebec prior to the legalization of same-sex marriage, only unmarried persons could apply for legal change of gender. With the advent of same-sex marriage, this restriction was dropped.

In the United States, transsexual and intersexual marriages typically run into the complications detailed above. As definitions and enforcement of marriage are defined by the states, these complications vary from state to state.
