¶1D.M.J. is a ten year old, half-Indian girl whose custody was awarded to her non-Indian mother in the 1976 divorce of her parents. In 1982 with the consent of the natural mother, an adoption was arranged with a married couple, appellees, who also happened to be non-Indian.
¶2Although the adoption proceeded in due course with a final Decree of Adoption on July 11,1983, it is from the order of February 24, 1983 that the father appeals. He is joined on appeal by Intervenor/Cherokee Nation and by the Oklahoma Indian Child Welfare Association, amicus curiae. We are asked to invalidate the proceedings of February 24 for the alleged failure of the trial court to comply with the Indian Child Welfare Act
¶3It is urged in behalf of appellant that the evidence offered in support of termination fell short of what is required under the 1.C.W.A. Appellees contend that the I.C. W.A. simply doesn’t apply to the placement (or adoption) of the child in this case. To resolve the question we must examine the Act in order to determine the purpose for its enactment.
¶4PURPOSE OF THE INDIAN CHILD WELFARE ACT AND OKLAHOMA INDIAN CHILD WELFARE ACT
¶5The Indian Child Welfare Act and Oklahoma Indian Child Welfare Act are structured around the concern “that an alarmingly high percentage of Indian families are broken up by the removal, often unwarranted, of their children from them by non-tribal public and private agencies” and placed in non-Indian homes and institu*1388tions.
"... [T]o protect the best interest of Indian children and to promote the stability and security of Indian tribes and families by the establishment of minimum federal standards for the removal of Indian children from their families and the placement of such children in foster or adoptive homes which will reflect the unique values of Indian culture....”5
¶6In adoption cases, the Act, where applicable, gives preferences for placement of the child with (1) a member of the child’s extended family, (2) other members of the Tribe, or (3) other Indian families.
¶7Numerous provisions of the Act support this conclusion.
¶8Section 1912 addresses pending court proceedings. Subsection (d) requires:
“Any party seeking to effect a foster care placement of, or termination of parental rights to, an Indian child under State law shall satisfy the court that active efforts have been made to provide remedial services and rehabilitative programs designed to prevent the breakup of the Indian family and that these efforts have proved unsuccessful.” (emphasis added).
¶9Subsection (e) declares:
“No foster care placement may be ordered in such proceeding in the absence of a determination, supported by clear and convincing evidence, including testimony of qualified expert witnesses, that the continued custody of the child by the parent or Indian custodian is likely to result in serious emotional or physical damage to the child.” (emphasis added).
¶10Subsection (f) states:
“No termination of parental rights may be ordered in such proceeding in the absence of a determination, supported by evidence beyond a reasonable doubt, including testimony of qualified expert witnesses, that the continued custody of the child by the parent or Indian custodian is likely to result in serious emotional or physical damage to the child.” (emphasis added).
¶11The Indian Child Welfare Act comes into play therefore, when we are confronted with the removal of Indian children from Indian families. The purpose of the Act is to promote the best interest of Indian children through promoting the stability and security of Indian tribes and families by the establishment of minimum federal standards for the removal of Indian children from their families.
¶12Oklahoma also has an Indian Child Welfare Act (OICWA).
¶13Appellant correctly points out that at the hearing there was no evidence of “remedial services and rehabilitative programs designed to prevent the breakup of the Indian family” as required by § 1912(d), nor was there testimony of “qualified expert witnesses that the continued custody of the ... Indian custodian” would be detrimental, as required by § 1912(f).
¶14But appellees counter that as far as D.M. is concerned, the family has been broken up since 1976. Once the family breakup *1389has occurred, preventive measures are logically impossible and “remedial services” cannot repair a relationship after seven years of divorce. They agree that expert testimony is required where “continued custody” of the Indian parent is at issue, but urge that the statute has no application when the child is and has been in the custody of a non-Indian parent, such as in this case.
¶15We must agree with the appel-lees/adoptive parents. The ICWA by its terms does not apply to “an award, in a divorce proceeding, of custody to one of the parents.”
¶16NOTICE TO THE CHEROKEE NATION
¶17The Cherokee Nation complains that the tribe received insufficient notice of the hearing.
¶18CONCLUSION
¶19The underlying purpose that is evident throughout the Indian Child Welfare Act is the Act’s concern with the removal of Indian children from an existing Indian family situation and the resultant breakup of the Indian family.
¶20We therefore conclude that the ICWA applies only in those situations where Indian children are being removed from existing Indian family environments. Under the facts of this case where the Indian child since 1976 has been in the custody of her non-Indian mother, where the child is not being removed from the custody of an Indian parent, and is not being removed from an Indian environment, the ICWA does not apply.
¶21We further conclude that the Cherokee Nation by appearing and participating in the hearing waived the statutory requirement of notice by certified mail.

¶35dissenting.
¶36The dispositive issue on appeal revolves around the Indian Child Welfare Act, 25 *1390U.S.C. § 1901 et seq. (I.C.W.A. or federal act) and the Oklahoma Indian Child Welfare Act, 10 O.S.Supp.1984 § 40 et seq. (O.I.C.W.A. or state Act) (collectively Acts). The issue is: Should the Acts apply to the hearing on the eligibility of D.M.J., an alleged Indian child, for adoption without the consent of appellant Parker Jr. Johnson, a divorced, noncustodial, Indian natural father. The majority’s decision places the adoption hearing outside the coverage of the Acts. I cannot accept the Court’s conclusion that the Acts do not apply. Accordingly, I dissent.
¶37Two threshold determinations are required to invoke the provisions of the Acts. First, the proceeding in question must be a “child custody proceeding” as defined by the federal Act. Second, it must be determined that the child is an “Indian child.” Matter of Appeal in Maricopa County, 136 Ariz. 528, 667 P.2d 228, 231 (Ct.App. 1983).
¶38There is no question that D.M.J. is an “Indian child” within the meaning of the Acts. Her father is a full blood Cherokee Indian and a member of the Cherokee Nation. Also, the Acts specifically define adoption cases as a “child custody proceeding.” See 25 U.S.C. § 1903(l)(iv).
¶39The majority holds the Acts do not apply in this case because the Indian child is in the custody of a non-Indian; therefore, there is no removal from an existing Indian family environment nor a resultant breakup of an Indian family. This interpretation completely thwarts the intent of the Acts.
¶40The congressional policy of the I.C.W.A. as set forth in 25 U.S.C. § 1902 is to protect the best interests of Indian children; to promote stability and security of Indian tribes and families; to establish minimum federal standards for the removal and placement of Indian children; and to provide assistance to tribes in the operation of child and family services. The I.C.W.A. was enacted as a result of evidentiary findings that Indian children were being removed from their families much more so than non-Indian children. It was determined that such high percentage of removal was due to absence of involvement of Indian tribes in the welfare and judicial system and the absence of understanding of Indian family life and culture by those persons administering that system.
¶41The Acts expressly except the application of their protective provisions in custody disputes arising in divorce proceedings under 25 U.S.C. 1903(1) and 10 O.S.Supp.1984 § 40.3(A). In my opinion the specific exceptions to the Acts’ applicability are unambiguous and include only divorce and delinquency proceedings. The majority, in essence, creates a judicial exception with regard to the applicability of the Acts. The creation of a judicial exception such as the one urged by appellees and created by the majority is inappropriate where the Acts are clear and unambiguous. I firmly believe the very language of the Acts dictates a finding that they unquestionably apply to this nonconsentual adoption hearing.
¶42It is apparent from the express language and the legislative history of the I.C.W.A. the concept of an Indian family also includes extended family members — aunts, uncles, grandparents, nieces, nephews, sisters or brothers-in-law, stepparents and first or second cousins. 25 U.S.C. § 1903(2); H.R.Rep. No. 1386, 95th Cong., 2d Sess. 20 (1977). Hence, D.’s Indian family consists of other persons than her nuclear family which includes her natural mother and father. The record reflects that D. lived for a period of time with her natural father and her paternal, Indian grandparents after the divorce. The termination of appellant’s parental rights effectually severs D.’s relationship with her extended family as well as her biological father. The overall intent of the I.C. W.A. is to protect Indian families, which I believe includes the protection of extended family members in the coverage of the Acts.
¶43Even if I were to find the application of the Acts were ambiguous, I still would disagree with the Court’s disposition, because the primary rule of construction of *1391Indian law is ambiguous provisions are to be interpreted for the benefit of Indians. Ahboah v. Housing Authority of the Kiowa Tribe, 660 P.2d 625, 631 (Okla.1983). Accordingly, Congressional intent “to prevent the separation of Indian children from family and tribal heritage” is not to be lightly observed. Matter of Appeal in Pima County, 130 Ariz. 202, 635 P.2d 187, 188 (Ct.App.1981). Today’s ruling creating a judicial exception only serves to militate against the minimum federal standards designed to protect the Indian child, family and tribe in involuntary proceedings where the appellant Indian father’s parental rights are terminated.
¶44I would find the hearing determining De-wana eligible for adoption without appellant’s consent is clearly within the ambit of the statutory definition of a child custody proceeding.
