Mr. Knowitall
We spoon feed you the law in this forum. There's a link at the top of the forum that answers frequently asked questions about emancipation, and another that provides links to state-specific information. Had you read either, or had you read any of the hundreds of threads that address emancipation in Texas, the hundreds of threads that ask, "I'm pregnant, so can I get emancipated," or the hundreds of threads that ask, "My parents/guardians are mean or abusive, so can I get emancipated", you wouldn't have needed to post a new thread.
As a basic threshold matter, for emancipation in Texas the minor must be 17 years of age, or at least 16 years of age and living separate and apart from the minor's parents, managing conservator, or guardian. The minor must also be self-supporting and managing the minor's own financial affairs. Your friend does not meet the basic requirements, even before we get to a best interest analysis.
If your friend believes she is being abused, she can involve protective services.
