Texas wants to keep a 14-year-old girl, believed to be married to jailed Polygamist Sect Leader Warren Jeffs in foster care permanently.
A status hearing on the teen's custody case will be held on Thursday in San Angelo.
She's the only one of 439 children taken from the Yearning for Zion Ranch in Eldorado to be returned to foster care.
The Associated Press reports documents and photos seized from the ranch showed the 14-year-old married at age 12 to Jeffs.
He leads the Fundamentalist Church of Jesus Christ of latter day saints.
Jeffs was convicted in 2007 as an accomplice to rape in Utah.
He awaits trial in Arizona and Texas on other charges related to alleged underage marriages.
