Thank you for the additional information. As a general rule, a person cannot win a lawsuit against somebody who filed a CPS complaint even if the complaint turned out to be wrong. The reason for this rule is to prevent a situation where a person fails to contact CPS for fear of a later lawsuit, and a child continues to be abused as a result. In other words, when weighing the harm that a baseless CPS complaint causes, and the harm that an unreported child abuse case causes, the legislature and courts have decided it is more important to error on the side of children.
There is an exception to the above, however. If the parent filed the CPS complaint in bad faith (i.e., she knew that there was no abuse and just wanted to cause trouble for you), then you do have a valid cause of action against the parent. The lawsuit would be for abuse of process. In other words, the parent used the legal system to harass you. In that situation, you may be able to win damages against the parent, including lost wages.
