Neglect is defined in Texas Family Code (TFC) §261.001(4) as an act or failure to act by a person responsible for a child's care, custody, or welfare evidencing the person's blatant disregard for the consequences of the act or failure to act that results in harm to the child or that creates an immediate danger to the child's physical health or safety. Abandonment is a subset of the statutory definition of neglect and involves leaving a child in a situation where the child would be exposed to an immediate danger of physical or mental harm, without arranging for necessary care for the child, and the demonstration of an intent not to return by a parent, guardian, or managing or possessory conservator of the child.
