In a state that bans same-sex marriage, it would seem to be easy to know who can legally marry. Texas county clerks will tell you it is not.

A two-year-old state law says a court order recognizing a sex or name change is acceptable for marriage license applicants. But a 1999 Texas appeals court ruling stipulates that, at least for purposes of marriage, medical procedures cannot change a person's sex — you are what you were at birth, period.

As I said in another thread, there is no legal definition of sex or gender. We live in the shadows or the legal gray area.
