A child protective services (CPS) decision in Texas could mean any of several things: there could be allegations that the child is living in an abusive home, or accusations of unfit parenting. CPS will investigate any claims and file a report. The results will either be a finding of substantiated or unsubstantiated allegations; in the latter situation, the case will be dropped. In the former, however, CPS may make the unilateral decision to remove the child from the home.
Retain or hire an attorney, or you may proceed pro se, i.e., on your own. It is highly recommended that you use an attorney, as navigating through red tape and court proceedings can be confusing, even in the best of times.
Respond as quickly as possible to the notice you will receive with the decision made by CPS. There is usually a time limit, such as 20 days, during which time you must file a written denial of wrongdoing. It would be wise to attach statements from any professionals with whom your child has come into contact, such as doctors or teachers or religious persons. CPS seldom second-guesses their decisions, which is why retaining an attorney is the best action to take.
Attend meetings and comply with instructions and orders, such as participating in parenting classes or anger management seminars. While you wait to hear from CPS, you can have a jump-start on fulfilling the requirements that CPS has imposed.
Document everything possible --- especially all communication from CPS --- and keep copies of all records and testimonies from other persons who can corroborate your side of the story. Stick to the facts and do not be sidetracked by emotions or irrelevant information.
