In 2017, the New Hampshire legislature enacted RSA 170–G:18, which established the Office of the Child advocate to oversee the state's child welfare, child protection and juvenile justice agency and to assure that the best interests of children are protected.

The full text of RSA 170–G:18 can be found on the New Hampshire General Court website.

In 2018, SB 479 was passed to amend RSA 170–G:18, expanding accessibility of our office, ensuring confidentiality of people who contact us, and allowing us to be more effective in our mandate.

The Department of Health and Human Services, through their Ombudsman Office, is still required to handle case specific complaints.
