A minor does not have the legal capacity to file a lawsuit on their own. As a result, they are required to have a representative file on their behalf. In Texas, this representative is called a 'next of friend.' A next of friend is simply a person who has been chosen to stand in the shoes of the minor and pursuing claims on their behalf.  Typically, the next of friend is a parent, legal guardian, or relative of the child.  The role of the next of friend is to act in the best interest of the minor and prosecute their rights.
