The Supreme Court has treated parental rights as a fundamental liberty under the Fourteenth Amendment for more than a century, protecting a parent’s authority to direct a child’s care, custody, and upbringing while allowing the state to step in when a child’s health or safety is genuinely at risk. The protection is strong but not absolute, and the Court has spent decades drawing the line between family autonomy and government power.
Where the Right Comes From
The Constitution never mentions parents or children. The protection comes from the Due Process Clause of the Fourteenth Amendment, which bars states from depriving any person of “life, liberty, or property, without due process of law.”1Constitution Annotated. Amdt14.S1.6.3.4 Family Autonomy and Substantive Due Process The Court has read “liberty” broadly enough to include raising children, and two early cases locked that reading in.
In Meyer v. Nebraska (1923), the Court struck down a state law banning the teaching of foreign languages to young children. The opinion defined Fourteenth Amendment liberty to include “the right of the individual to contract, to engage in any of the common occupations of life, to acquire useful knowledge, to marry, establish a home and bring up children.”2Justia. Meyer v. Nebraska, 262 U.S. 390 (1923) Two years later, Pierce v. Society of Sisters (1925) struck down an Oregon law requiring all children to attend public schools, holding that the “fundamental theory of liberty upon which all governments of this Union rest excludes any general power of the State to standardize its children by forcing them to accept instruction from public teachers only.”3Justia U.S. Supreme Court Center. Pierce v. Society of Sisters, 268 U.S. 510 (1925)
Together, Meyer and Pierce set two principles that still control: parents have a protected liberty interest in directing their children’s upbringing, and the state cannot use its regulatory power to force a uniform model of child-rearing. Later decisions build on this foundation. Washington v. Glucksberg (1997) placed “the rights to … direct the education and upbringing of one’s children” among the fundamental liberties protected by substantive due process, citing both cases.4Justia. Washington v. Glucksberg, 521 U.S. 702 (1997)
When the State Can Override a Parent
Parental rights have never been unlimited. In Prince v. Massachusetts (1944), the Court upheld a child labor conviction against a guardian who had a nine-year-old distribute religious literature on the streets at night. The opinion drew the line clearly: “The family itself is not beyond regulation in the public interest, as against a claim of religious liberty,” and “neither rights of religion nor rights of parenthood are beyond limitation.”5Justia. Prince v. Massachusetts, 321 U.S. 158 (1944)
Prince established that the state, acting as parens patriae, can restrict parental choices when a child’s health, safety, or welfare is at stake. The Court noted that “the state’s authority over children’s activities is broader than over like actions of adults” and that the right to practice religion “does not include liberty to expose the community or the child to communicable disease or the latter to ill health or death.”5Justia. Prince v. Massachusetts, 321 U.S. 158 (1944) That holding supplies the constitutional basis for compulsory vaccination, mandatory schooling, and child abuse and neglect laws. Nearly every case where a court overrides a parent’s decision starts here.
Education and Religious Upbringing
Compulsory education creates one of the sharpest conflicts between state authority and parental choice. In Wisconsin v. Yoder (1972), Amish parents refused to send their children to school past the eighth grade; Wisconsin required attendance through age sixteen. The Court sided with the parents, holding that the state’s “interest in universal education is not totally free from a balancing process when it impinges on other fundamental rights, such as those specifically protected by the Free Exercise Clause of the First Amendment and the traditional interest of parents with respect to the religious upbringing of their children.”6Justia U.S. Supreme Court Center. Wisconsin v. Yoder, 406 U.S. 205 (1972)
The Court emphasized this was a narrow ruling. The Amish had offered “convincing evidence” that one or two additional years of formal schooling would not impair their children’s health, self-sufficiency, or ability to function as citizens.6Justia U.S. Supreme Court Center. Wisconsin v. Yoder, 406 U.S. 205 (1972) The decision turned on sincere religious belief and centuries of tradition, not personal preference. A parent who simply disagrees with the curriculum would not get the same result.
Curriculum Opt-Outs After Mahmoud v. Taylor
In June 2025, the Court returned to the tension between parental religion and public school requirements in Mahmoud v. Taylor. Parents challenged a school board that refused to let them opt their children out of lessons involving storybooks that conflicted with their religious beliefs. The Court ruled that the parents were “entitled to a preliminary injunction” and ordered the board to notify them in advance when the challenged materials would be used and to let their children be excused.7Supreme Court of the United States. Mahmoud v. Taylor, No. 24-297 (2025)
The decision does not give parents blanket veto power over curriculum. It addressed specific books and a board policy that categorically denied every opt-out request. How broadly schools must accommodate religious objections to other materials is still unsettled.
Medical Decisions for Children
The same presumption that parents act in their children’s best interests extends to medical choices. In Parham v. J.R. (1979), the Court upheld a parent’s authority to admit a child to a psychiatric facility over the child’s objection, holding that “the traditional presumption that the parents act in the best interests of their child should apply” and that parents “retain plenary authority to seek such care for their children, subject to a physician’s independent examination and medical judgment.”8Justia. Parham v. J.R., 442 U.S. 584 (1979)
The Court did not hand parents unchecked power. It required a “neutral factfinder,” which can be the admitting physician, to independently decide whether the medical standards for commitment are met, with periodic review of the child’s continued need for treatment.8Justia. Parham v. J.R., 442 U.S. 584 (1979) The safeguard is medical rather than judicial; the Court rejected the argument that a formal courtroom hearing is constitutionally required.
Outside the Supreme Court, state courts apply the Prince framework when parents refuse treatment. Courts are far more likely to override a refusal when the child faces a life-threatening condition and the proposed treatment has a high success rate. When treatment carries significant risks or low odds of success, courts tend to defer to the parent. Religious objections receive more legal protection than objections based on personal skepticism, though neither is absolute when a child’s life is at stake.
Unmarried and Non-Biological Parents
The early cases all involved married couples, which left unmarried fathers in constitutional limbo until Stanley v. Illinois (1972). Peter Stanley had lived with his children and their mother for years but never married her. When she died, Illinois made his children wards of the state with no hearing on whether he was a fit parent. The Court struck down the procedure, holding that “the State cannot, consistently with due process requirements, merely presume that unmarried fathers in general … are unsuitable and neglectful parents. Parental unfitness must be established on the basis of individualized proof.”9Justia. Stanley v. Illinois, 405 U.S. 645 (1972)
Every parent is now entitled to a hearing on fitness before losing custody, regardless of marital status. For non-biological parents, the key modern case is V.L. v. E.L. (2016). A same-sex couple had their children through one partner’s biological parentage, and the other partner adopted through a valid Georgia court order. When the couple separated and the biological mother moved to Alabama, Alabama’s courts refused to recognize the Georgia adoption. The Supreme Court reversed per curiam, holding that the Full Faith and Credit Clause requires every state to give effect to valid adoption judgments from other states.10Justia. V.L. v. E.L., 577 U.S. 464 (2016) Once a court with proper jurisdiction finalizes an adoption, no other state can undo that parent-child relationship.
Extended Family
Constitutional protection reaches beyond two parents and their biological children. In Moore v. City of East Cleveland (1977), a grandmother was convicted under a zoning ordinance for living with two grandsons who were cousins rather than siblings, because the city defined “family” so narrowly her household violated the housing code. The Court struck down the ordinance, holding that constitutional protection for the “sanctity of the family” extends beyond the nuclear family and is “not confined within an arbitrary boundary.”11Justia. Moore v. City of East Cleveland, 431 U.S. 494 (1977) Governments cannot define “family” in a way that excludes relatives who are actually raising children.
Terminating Parental Rights
Permanently severing the legal bond between a parent and child is the most drastic action a state can take in family law. The Court has imposed two procedural safeguards: a heightened burden of proof and, in some circumstances, the right to an attorney.
Clear and Convincing Evidence
In Santosky v. Kramer (1982), the Court ruled that New York’s “fair preponderance of the evidence” standard in termination proceedings violated due process. More-likely-than-not is the standard for ordinary money disputes. The Court held that “before a State may sever completely and irrevocably the rights of parents in their natural child, due process requires that the State support its allegations by at least clear and convincing evidence.”12Library of Congress. Santosky v. Kramer, 455 U.S. 745 (1982)
The reasoning turned on how errors should be distributed. An erroneous failure to terminate leaves a child in a difficult situation, but an erroneous termination “unnecessarily destroys the natural family,” a harm the Court viewed as more severe. The clear and convincing standard applies whether the case involves neglect, abandonment, or abuse.12Library of Congress. Santosky v. Kramer, 455 U.S. 745 (1982)
The Right to an Attorney
Given what is at stake, you might expect the Constitution to guarantee a lawyer for every parent who cannot afford one. It does not. In Lassiter v. Department of Social Services (1981), the Court held there is no automatic right to appointed counsel in termination cases. Trial judges evaluate each case using the balancing test from Mathews v. Eldridge: the parent’s private interest, the government’s interest, and the risk that proceeding without a lawyer would lead to a wrong result.13Justia. Lassiter v. Department of Svcs., 452 U.S. 18 (1981) Many states have filled the gap by providing counsel in termination proceedings as a matter of state law, but the federal constitutional floor remains case-by-case.
Grandparents, Visitation, and the Fit Parent Presumption
Grandparents, stepparents, and other relatives sometimes seek court-ordered visitation over a parent’s objection. Every state has some form of third-party visitation statute, and the Court placed real limits on them in Troxel v. Granville (2000).
Washington State’s law allowed “any person” to petition for visitation “at any time” and let judges grant it whenever it served the child’s best interest. A mother had limited her children’s visits with their paternal grandparents after their father’s death. The grandparents petitioned for more time, and the trial judge granted it. The Court reversed, finding the statute unconstitutional as applied because it gave no special weight to the mother’s decision. A fit parent is presumed to act in the child’s best interest, and a judge cannot substitute a different visitation schedule based on the judge’s own view of what would be better.14Justia. Troxel v. Granville, 530 U.S. 57 (2000)
The Washington Supreme Court had gone further, holding that the Constitution permits the state to interfere with parental decisions “only to prevent harm or potential harm to the child.”14Justia. Troxel v. Granville, 530 U.S. 57 (2000) The U.S. Supreme Court did not explicitly adopt or reject that harm standard, which left states to develop their own thresholds. Some require proof of actual harm; others require only a best-interest showing with appropriate deference to the parent. Protection varies significantly from state to state as a result.
The Scrutiny Question the Court Has Not Answered
Here is the puzzle at the center of this area of law. The Court repeatedly calls parental rights “fundamental,” but it has never clearly stated what level of constitutional scrutiny applies when the government restricts them. The Troxel plurality said explicitly: “We do not, and need not, define today the precise scope of the parental due process right in the visitation context.” Justice Thomas noted in his concurrence that “none of” the opinions in the case “articulates the appropriate standard of review.”15Cornell Law Institute. Troxel v. Granville, 530 U.S. 57 (2000)
The gap matters. If parental rights trigger strict scrutiny, any government restriction must be narrowly tailored to serve a compelling interest, and most regulations would fail. If they get something less demanding, governments have more room to regulate. The Court’s refusal to pick a lane is a major reason parental rights receive different levels of protection depending on the state. What is settled is that these rights belong to the category of liberties the Court considers “deeply rooted in this Nation’s history and tradition,” which has insulated them from the uncertainty that followed Dobbs v. Jackson Women’s Health Organization (2022) in a different context.
Federal Power Over Family Law
Most parental rights disputes pit individual parents against a state government, but family law is not exclusively a state matter. Haaland v. Brackeen (2023) addressed whether Congress itself can set rules for custody and adoption proceedings involving Native American children. The Indian Child Welfare Act requires state courts to follow specific placement preferences and to make “active efforts” to keep Native families together before terminating parental rights. Several states and individual plaintiffs challenged the law as exceeding federal authority.
The Court upheld ICWA 7–2, ruling it “consistent with Article I” and within Congress’s broad authority to legislate on matters involving Indian tribes. The Court noted that “when Congress validly legislates pursuant to its Article I powers,” it has not hesitated to find conflicting state family law preempted.16Supreme Court of the United States. Haaland v. Brackeen, No. 21-376 (2023) ICWA’s heightened protections for Native families remain the law, and state courts must apply them in covered proceedings. Equal protection and nondelegation challenges were dismissed on standing grounds, leaving those constitutional questions open.
