Relinquishment of a child may be effectively revoked within a reasonable time after its execution before the child placement agency has, in writing, accepted full responsibility for the child. Kellie v. Lutheran Family & Social Service, 208 Neb. 767, 305 N.W.2d 874 (1981).

In an agency adoption, the rights of the relinquishing parent are terminated when the agency accepts responsibility for the child in writing, and once the agency accepts such responsibility, the agency retains custody until such time as the child is actually adopted; whereas in a private adoption, the child is relinquished directly into the hands of the prospective adoptive parents without interference by the state or a private agency, and the relinquishing parent's rights are not totally extinguished until the child has been formally adopted by the prospective parents. Gomez v. Savage, 254 Neb. 836, 580 N.W.2d 523 (1998).

The statute requires both a written relinquishment and a written acceptance. D.S. v. United Catholic Soc. Servs., 227 Neb. 654, 419 N.W.2d 531 (1988).

The legislative intent as to the finality of a child relinquishment is not the same in the case of a private placement, governed by section 43-111, R.R.S.1943, as it is in an agency placement, governed by section 43-106.01, R.R.S.1943. Gray v. Maxwell, 206 Neb. 385, 293 N.W.2d 90 (1980).
