Child Custody

I would highly recommend that you consult with an attorney to determine what options that you may have.  In order to proceed you need to make sure that the Court understands that you have the right to request the Court to award you custody or, as we call it in Texas, conservatorship of your sibling.  This means you have to have "standing".  Standing and jurisdiction are complicated ideas to understand, sometimes even for lawyers, but if you do not understand them you may have trouble proceeding and getting the chance to ask the Court to consider what you are requesting.  While in the state of Texas anyone can represent themselves, it is seldom a good idea to do so.
