"I am now officially emancipated!!!" she wrote on Twitter last week. "I'm really lucky I have an amazing support system and lovely people in my life who have given me the support and guidance to have been given this wonderful opportunity. Most importantly I want to thank [sister] @shanelle_gray and my father for their special support regarding this matter, I really couldn't have done it without them."
Gray was granted permanent custody of Winter in May 2014 while Winter’s father, Glenn Workman, was awarded guardianship over her finances.
And although Winter is interested in law school, she won't be giving up the acting career just yet.
"I would love to continue acting but it's definitely important, I think, to go and do something else as well," Winter explained. "You never know if something's not going to work out, if one day acting is like, 'No, we don't like you anymore!' You gotta have something else you can do."
