Under the laws of all states in this country there is no per se time period for social services to decide if a child custody matter will be opened or not. Ordinarily social services needs to engage in a proper investigation of all facts of a given matter which simply takes time.Once a report is made, it is reviewed and decided if further action is needed or not. There is no set time period to pursue the matter nor is there a time period where the information in the report expires.
