Mississippi Code Title 93. Domestic Relations § 93-17-223

In cases where only one (1) of the birth parents has authorized the release of identifying information, that birth parent shall be prohibited from divulging to the adoptee the identity, or any information reasonably calculated to lead to discovery of the identity, of the other birth parent, and shall execute a sworn affidavit stating that no such information shall be revealed. The refusal of any birth parent to comply with this prohibition shall constitute an act of bad faith under the terms of Sections 93-17-201 through 93-17-223, and such birth parent shall be subject to civil liability for the release of such information.
