A minor can not choose where to live. Your grandparents can apply for custody after the parental rights have been given up or taken from your parents by the court. If you are living in a unsafe environment you have to tell someone or call the CPS.
In Texas, if a child is 14 or older, he/she can choose to live with a grandparent as long as permission is given by the custodial parent.
Only if his or her parent(s) or primary custodial parent agrees to the living arrangements.
Minor's are not allowed to choose with whom they wish to live, although the judge may speak with the child and take his or her opinions into consideration when making custodial decisions. Likewise, the grandparent who has temporary custody cannot release the minor into the custody of any other person including a parent without first obtaining permission from the court.
