NOLAN, J.
A mother of five children makes a two-fold appeal: (1) from the adjudications that her children were in need of care and protection pursuant to G.L.c. 119, § 24 (1986 ed.), and (2) from the allowance of the petitions to dispense with consent to the adoption of these children under G.L.c. 210, § 3 (1986 ed.). A judge of the District Court Department was authorized to hear the petitions by the Chief Administrative Justice of the Trial Court acting under the authority of G.L.c. 210, § 3 ( b). See Adoption of Emily, 25 Mass. App. Ct. 579, 581 n. 3 (1988). We transferred the case to this court on our own motion. There was no error in the judge's decision regarding the five minors.
1. " Moffett" brief. We note the filing of a so-called " Moffett" brief in connection with the issue whether there was clear and convincing evidence of the mother's unfitness. The term is derived from Commonwealth v. Moffett, 383 Mass. 201, 207-209 (1981), in which the court set forth guidelines to appointed counsel in a criminal case who, the court said, "should not be permitted to withdraw solely on the ground that the appeal is frivolous or otherwise lacking in merit." Id. at 207. At the same time, counsel, appointed as well as retained, has the responsibility not to advance groundless contentions. See S.J.C. Rule 3:07, DR 7-102 (A)(2), as appearing in 382 Mass. 785 (1981). The court suggested that, when there is nothing to support a contention which a party, "despite counsel's attempts to dissuade him, insists on pursuing, we think it preferable that counsel present the contention succinctly in the brief in a way that will do the least harm to [a party's] cause." Commonwealth v. Moffett, supra at 208.
In the present case, counsel has done just this. We have already held that in care and protection cases, "parents are entitled to the effective assistance of counsel." Care Protection of Stephen, 401 Mass. 144, 149 (1987). We are asked to apply Moffett to a care and protection case. We do so.
2. Care and protection. The record is replete with clear and convincing evidence after three days of trial that both parents are "unfit to further the welfare and the best interests of the [children]." Care Protection of Stephen, supra at 150. The judge's findings must be left undisturbed, absent a showing that they are clearly erroneous. Custody of Two Minors, 396 Mass. 610, 618 (1986). The judge made approximately one hundred findings. They were detailed, thoughtful, and sensitive. He made findings as to each child. There was no error.
The mother's argument that the findings were not detailed as to each child is unpersuasive because the mother's unfitness was the same as to each child.
3. G.L.c. 210. The mother raised no objection below to the various plans submitted by the department, including the plan adopted and ordered by the judge and, therefore, her belated challenge to the plan is not properly before the court. Massachusetts Ass'n of Older Americans, Inc. v. Commissioner of Ins., 393 Mass. 404, 413-414 (1984).
However, we have considered her arguments, and we conclude that they are without merit. The judge in this proceeding took evidence and made approximately one hundred findings of fact. He made findings as to each child. His findings were careful, exhaustive, and based on overwhelming evidence. He approved a plan of the Department of Social Services (department) that all five children be adopted by a two-parent family and concluded that such a plan was realistic and in the best interests of the children. See G.L.c. 210, § 3 (c). There is no need to withhold action until such a family is found.
4. Conclusion. The judge's orders committing the children to the care and protection of the department and the orders allowing the petitions to dispense with the need for consent to adoption are affirmed.
So ordered.
