Abstract
This article examines whether maternal and paternal DNA testing should be mandatory at birth in South Africa. A paternal-only test may establish that a presumed father is not biologically related to a child, but it cannot detect cases in which the child is also unrelated to the presumed mother because of hospital-switching or mistaken identification. The article argues for a three-person DNA test involving the newborn, the recorded mother and the declared or alleged father. It considers the child’s rights to identity and parental care alongside parental privacy, dignity, and bodily integrity. It proposes a confidential and regulated system with restricted data use, accredited laboratories, counselling, and safeguards for adoption, surrogacy, and assisted reproduction. The article concludes that mandatory parentage verification may be justified where its primary purpose is protecting children rather than investigating parental misconduct.

I. Introduction
A child may grow up in a loving family while unknowingly being separated from both biological parents. Where babies are mistakenly switched in hospitals, the mother may raise a child believing that the child is biologically hers. Years later, a paternity test may reveal that the presumed father is not the biological father. That result may appear to establish misattributed paternity while concealing the more serious possibility that the child is also not biologically related to the mother who raised the child. This possibility demonstrates the limitations of a paternal-only approach to DNA testing. A paternity test compares a child with an alleged father, but it does not establish whether the child belongs to the mother who gave birth to or received the child. A complete parentage test involving the child, mother, and alleged father can identify biological relationships more accurately. It may also expose hospital-switching, unlawful removal, trafficking, mistaken identification, and serious failures in maternity-record systems.
South African law already recognizes the importance of children’s identity, family care, parental responsibilities and the best interests of the child. Section 28 of the Constitution of the Republic of South Africa[1] (the Constitution) grants every child the right to a name and nationality from birth, family or parental care, and protection from maltreatment, neglect, abuse or degradation. It further provides that a child’s best interests are paramount in every matter concerning the child[2]. The Children’s Act[3] 38 of 2005 regulates parental responsibilities, paternity disputes and access to genetic-parent information. However, the existing framework generally treats DNA testing as a remedy used after a dispute arises, rather than as a preventive safeguard applied at birth[4].
This article argues that South Africa should introduce a carefully regulated system of mandatory parentage verification at birth involving the newborn child, the mother and the recorded or alleged father. The proposal should not be understood as a compulsory investigation into the sexual conduct of mothers or fathers. Its primary purpose should be the protection of the child’s identity, the prevention of baby-switching, and the accurate creation of birth and medical records. The article first examines the existing constitutional and statutory framework. It then analyses the benefits and risks of mandatory testing, considers the privacy and dignity implications, and proposes a rights-compliant model for implementation in South Africa.
II. The Existing Legal Framework.
A. Constitutional protection of children.
The constitutional foundation for mandatory parentage verification is section 28 of the Constitution[5]. Every child has the right to a name and nationality from birth, family or parental care, and protection from maltreatment, neglect, abuse or degradation. Section 28(2) of the Constitution[6] further provides that a child’s best interests are paramount in every matter concerning the child. These rights are directly relevant to birth identification. A child’s identity is not merely an administrative matter. It affects nationality, family relationships, inheritance, maintenance, medical history, and the development of personal identity. If a child is incorrectly recorded or placed with the wrong family, the error may affect the child throughout their life.
The Constitution[7] also protects human dignity, bodily integrity, and privacy. Section 10 of the constitution[8] protects everyone’s inherent dignity; section 12(2)[9] of the Children’s Act protects bodily and psychological integrity, and section 14 of the Constitution[10] protects privacy. A mandatory DNA scheme would therefore limit important rights and would have to comply with section 36 of the Constitution[11]. Any limitation must be authorized by law, reasonable and justifiable in an open and democratic society, having regard to the importance and purpose of the limitation, its nature and extent, and the availability of less restrictive means[12]. The constitutional question is therefore not simply whether DNA testing is useful. The central question is whether compulsory testing can be designed in a manner that sufficiently protects children while limiting the privacy and bodily rights of parents as little as reasonably possible.
B. The Children’s Act 38 of 2005.
The Children’s Act[13] gives effect on constitutional rights concerning children and parental care. Its objects include strengthening families, protecting children from maltreatment, and promoting their physical, psychological, intellectual, emotional, and social development[14]. The Act confirms that the best interests of the child are of paramount importance. Sections 18 to 21 of the Children’s Act regulate parental responsibilities and rights[15]. Section 19 of the Children’s Act[16] recognizes the responsibilities and rights of mothers; section 20 of the Children’s Act[17] deals with married fathers, and section 21of the Children’s Act[18] addresses unmarried fathers. Section 26 of the Children’s Act[19] permits a person claiming to be the biological father to apply for amendment of birth registration or to approach a court for an order confirming paternity where consent is unavailable or refused[20].
Section 36 of the Children’s Act[21] creates a rebuttable presumption of paternity in relation to a child born out of wedlock where a person had sexual intercourse with the mother during the period in which the child could have been conceived. Section 37 0of the Children’s Act[22] provides that a refusal to submit to blood samples in paternity proceedings may be considered as evidence against the refusing party[23].These provisions show that South African law accepts scientific testing as relevant to determining biological parentage. They operate primarily in the context of a dispute, court application or challenge to paternity. The Act also recognizes the importance of genetic origins. Section 41 of the Children’s Act[24] concerns access to biographical and medical information relating to genetic parents. This reflects the principle that knowledge of biological origins may be important to a child’s medical welfare and personal identity [25]. Nevertheless, the Act does not establish a universal procedure for confirming the identity of the mother and father immediately after birth.
C. Birth registration and parentage.
Birth registration records the legal identity of a child. It is not necessarily a genetic-verification system. The accuracy of birth registration depends on information provided by parents and health officials, together with reliable hospital identification and maternity procedures. Where a baby is accidentally or unlawfully switched, the birth record may reproduce the original error. If the mother is incorrectly matched with the child, later paternity testing may create confusion rather than clarity. A result excluding the presumed father may lead the family to conclude that the mother had a sexual relationship with another man. The actual cause may be that the child is unrelated to both presumed parents. A three-person parentage test would reduce this risk. It could determine whether the child shares a biological relationship with the mother and whether the presumed father is genetically consistent with the child. DNA cannot by itself determine every form of legal parenthood, but it can establish or exclude biological relationships when collected and analyzed through reliable procedures.
South African courts have recognized that scientific testing may assist the resolution of paternity disputes. In LB v YD 2009 (5) SA 463 (T)[26], the High Court considered the court’s authority to order scientific testing where determination of biological parentage was relevant to the interests of the child and the administration of justice.^10 In YM v LB 2010 (6) SA 432 (SCA)[27], however, the Supreme Court of Appeal cautioned that scientific testing should not be ordered mechanically where paternity had already been established on the evidence and testing would not serve the child’s interests[28]. These cases demonstrate both the evidential value of DNA and the need for a child-centered, proportionate approach.
III. The Case for Mandatory Three-Person Testing.
A. Protecting the child’s identity.
The strongest argument for mandatory testing is that the child is the person most affected by a parentage error. Adults may experience emotional distress, financial consequences or reputational harm, but the child may lose access to biological family, medical information, nationality, inheritance, and cultural identity. A child’s right to know biological origins is particularly significant where an incorrect parentage record continues for many years[29]. Medical history may be unavailable or wrongly attributed. A child may unknowingly inherit a genetic condition without access to the correct family history. In adulthood, discovering a mistaken identity can cause psychological injury and disrupt established family relationships. Mandatory testing at birth would identify errors before family bonds become deeply entrenched. This does not mean that biological parentage should automatically displace social or legal parenthood. It means that the State should ensure that relevant biological information is known and securely recorded before legal and administrative decisions become difficult to correct.
B. Preventing baby-switching and unlawful removal.
Baby-switching may occur through negligence, inadequate identification procedures, deliberate misconduct, or criminal activity. The risk is not limited to deliberate abduction. A hospital may incorrectly label a baby, release a child to the wrong person, or fail to maintain reliable records. A mandatory test would create an additional verification layer. Hospital bracelets, fingerprints, photographs, electronic records and controlled handover procedures remain necessary, but DNA testing could function as an independent audit. It would be particularly valuable where records are incomplete, staff members change, babies are transferred between hospitals, or the child is born during an emergency. Testing could also assist investigations into child trafficking and unlawful removal. The Children’s Act[30] contains provisions dealing with child abduction and trafficking, including the recruitment, transfer, receipt or harbouring of children through coercion, deception, abuse of power or vulnerability[31]. A reliable parentage record could assist authorities in detecting irregular transfers and identifying children separated from their families.
C. Why paternal-only testing is inadequate.
A paternal-only test is often justified as a means of protecting men from raising children who are not biologically theirs or from paying maintenance for children unrelated to them. Those concerns may be legitimate, but a paternal-only test is incomplete.
If the test excludes the alleged father, at least three possibilities may exist:
“The mother had sexual relations with another man;
The alleged father is not the biological father because of assisted reproduction or another lawful arrangement; or
The child is not biologically related to the mother because of a hospital-switching or identity error.”[32]
Only a test involving the mother can identify the third possibility. Mandatory testing should therefore be framed as a child-identification measure rather than an anti-mother or anti-infidelity measure. The mother and father should be treated equally as sources of genetic information, while the child remains the central rights-holder.
D. Medical and administrative benefits.
Accurate parentage information may assist in medical treatment, genetic counselling, and the identification of hereditary diseases. It may also reduce future litigation involving maintenance, succession, citizenship, parental responsibilities, and amendment of birth records. The Children’s Act’s[33] recognition of access to genetic-parent information demonstrates that biological information may have continuing importance for a child. A system verifying parentage at birth would make that principle practical rather than leaving children to discover their origins through accidental testing, family disputes or medical emergencies.
IV. Constitutional and Ethical Limitations.
A. Privacy and bodily integrity.
DNA contains extensive information. A biological sample taken for parentage testing may reveal information beyond the immediate identity question, including health-related and familial information. Compulsory collection therefore implicates privacy, bodily integrity, and informational self-determination. The Constitution protects everyone’s privacy and bodily integrity[34]. A mandatory scheme could not permit hospitals, government departments, or laboratories to use the sample for unrelated purposes. It would also be constitutionally problematic to retain samples indefinitely, sell genetic information, share it with insurers or employers, or use it for criminal investigations without a separate lawful basis. The proposal must distinguish between collecting a limited DNA profile for parentage verification and creating a broad genetic database. Only the minimum information necessary to confirm parentage should be generated and retained.
B. Protection of genetic information under POPIA.
POPIA defines biometrics to include DNA analysis[35]. It also regulates the processing of special personal information and the personal information of children[36]. These provisions are relevant because a newborn’s genetic information is both highly sensitive and connected to a person who cannot independently consent. A compulsory testing system would require a clear statutory basis. The purpose must be specific, explicitly defined, and lawful. The information collected must be adequate, relevant, and not excessive. POPIA[37] also requires responsible parties to limit retention, maintain security safeguards, and notify data subjects of collection and security compromises. The proposed legislation should therefore supplement POPIA[38] rather than bypass it. DNA samples should not be placed in a general criminal database. Results should be used only for parentage verification, correction of identification errors, child protection, and related medical-record purposes. Unauthorized disclosure should attract serious sanctions.
C. Consent and the newborn child.
A newborn cannot provide informed consent[39]. Ordinarily, a parent or lawful guardian would consent on the child’s behalf. If testing is mandatory, however, parental refusal could not prevent the test entirely. This creates a difficult question concerning the relationship between parental authority and the child’s independent rights. The answer should be that parents act as custodians of the child’s interests rather than owners of the child’s identity. Where a measure is designed to protect the child from misidentification, the State may justify limited testing despite parental objection, provided that the process is lawful, proportionate, and confidential. The mother and alleged father should nevertheless receive clear information about the purpose of testing, the nature of the sample, the possible results, and available counselling. Formal consent may not be required, but informed notice and procedural fairness remain essential.
D. Biological and legal parenthood.
Biological parentage does not always determine legal parenthood. Children may be adopted, conceived through donor gametes, born through surrogacy or raised by a person who is not genetically related but has assumed parental responsibilities. The Children’s Act[40] excludes certain biological relationships from the statutory definition of ‘parent’, including a gamete donor in artificial fertilization. Therefore, a DNA result cannot automatically determine who has parental responsibilities and rights. A mandatory testing system must record biological information separately from legal parenthood. The result should not automatically remove a child from a family or cancel a person’s parental status. Instead, it should trigger a confidential review by an appropriate authority where the genetic result conflicts with the declared legal or social relationship.
E. Emotional harm and family disruption.
A test may reveal infidelity, donor conception, rape, incest or an unexpected family relationship. If results are disclosed carelessly, testing could cause violence, abandonment, or psychological harm. The State must therefore provide counselling and safeguards before results are released. An unexpected exclusion should first be reviewed by an accredited laboratory and a trained professional. The parties should receive counselling and an explanation that exclusion does not itself prove misconduct. A second confirmatory test should be available before any legal or administrative action is taken.
V. A Proposed South African Framework.
A. The three-person test.
Parliament should amend the Births and Deaths Registration Act[41] and relevant health legislation to establish mandatory parentage verification for births occurring in public and private health establishments.
The standard test should involve:
the newborn child;
the woman recorded as the mother; and
the man recorded or declared as the father, where a father is identified.
Where no father is identified, the child and mother should still be tested to verify maternity and prevent switching. The absence of an alleged father should not delay birth registration, discharge, healthcare or temporary identity documentation.
Testing should use a non-invasive cheek swab wherever possible. It should not interfere with urgent medical treatment or impose unreasonable pain or risk on the child.
B. Limited purpose and data protection.
The legislation should state that the test may be used only for:
confirming or excluding biological maternity and paternity;
correcting an identification error;
protecting the child from trafficking, unlawful removal or misplacement; and
ensuring accurate medical and civil records.
The genetic sample should be destroyed after the legally necessary period, unless a court orders otherwise or the parties’ consent to lawful preservation for a specific medical purpose. The DNA profile should not be placed in a general criminal database. Access should be restricted to the health establishment, the authorized laboratory, the Department of Home Affairs[42], and designated child-protection authority. The statutory scheme should incorporate POPIA’s[43] principles of purpose limitation, data minimization, security safeguards, and accountability. Because DNA is biometric information and the child’s information is specially protected, heightened security and strict access controls are necessary.
C. Accredited laboratories and chain of custody.
Testing should be conducted only by accredited laboratories subject to quality control standards. Samples must be collected using documented procedures and linked to the correct newborn through at least two independent identifiers.
The process should include:
identity verification before sample collection;
two trained healthcare workers witnessing collection;
tamper-evident packaging;
secure electronic tracking;
separation of sample collection from result authorization; and
independent review of any exclusion results.
These safeguards are necessary because a DNA test is only as reliable as the sample and chain of custody. A laboratory cannot correct a sample that was taken from the wrong baby or attached to the wrong record[44].
D. Handling unexpected results.
An unexpected result should not immediately be communicated in a manner that creates blame. The hospital should classify the result as required by review and arrange a confirmatory test. Parents should receive counselling from a social worker, psychologist, or family advocate. If the mother is excluded, the child should remain safely with the person caring for the child unless there is evidence of abuse, trafficking, or immediate danger. The best interests of the child must guide every placement decision. The genetic result should trigger investigation, not automatic removal[45]. If the father is excluded but the mother is confirmed, the result should initially be treated as a private parentage issue unless there is evidence of fraud, abuse or another offence. The alleged father should not automatically be deprived of a social relationship with the child. The law must recognize that a child may have an important emotional relationship with a non-biological parent.
E. Special circumstances.
The law should provide special procedures for[46]:
donor conception;
artificial fertilization;
surrogacy;
adoption;
anonymous births;
rape and incest;
births where a parent is deceased or unavailable;
emergency births where testing is temporarily impossible; and
cases where disclosure could expose the mother or child to violence.
In assisted reproduction and surrogacy, testing should confirm the relevant reproductive records without treating a gamete donor as a legal parent. In adoption, testing should not be used to undermine a valid adoption order, although it may protect the child’s right to medical and biographical information. When testing is impossible at birth, it should be completed within a prescribed period. The absence of a result should not prevent the child from receiving a birth certificate, healthcare, or parental care.
VI. Counterarguments and Responses.
A. Cost and administrative capacity.
One objection is that mandatory testing would be too expensive for South Africa’s public healthcare system. This concern is serious, particularly in rural and under-resourced areas. However, the State already bears significant costs when identity disputes emerge years later. Litigation, social-work investigations, maintenance disputes, cross-border tracing and psychological support may be more expensive than early verification. A phased implementation could begin in maternity hospitals with the highest birth volumes and gradually extend to all facilities. Public funding would be essential because the system should not make accurate identity dependent on a parent’s ability to pay.
B. Family disruption.
A second objection is that testing would damage families by revealing private information. That risk exists, but secrecy does not necessarily protect children. It may postpone discovery until the child is older, and the consequences are more severe. The appropriate response is confidential counselling, limited disclosure, and separation of biological information from legal parenthood. The objective should be accurate information and child protection, not the automatic reorganization of families.
C. Assumption of parental dishonesty.
A third objection is that mandatory testing treats every parent as dishonest. The proposal should not be based on an assumption of dishonesty. It should be based on the institutional risk of human error and the seriousness of misidentifying a child. Hospitals already use identification procedures even though most healthcare workers are trustworthy. DNA testing would be an additional safeguard rather than an accusation against parents.
D. The danger of biological reductionism.
A fourth objection is that biological truth should not always control family law. That argument is correct. Biological parentage is not the only basis of parenthood. The proposed framework therefore does not require automatic changes to custody, adoption or parental responsibilities.
It requires accurate knowledge, followed by a best-interested assessment where legal and biological relationships differ. A child’s established emotional bonds must remain central.
VII. Conclusion.
South African law strongly protects children’s identity, family care, dignity and best interests. The Children’s Act recognizes paternity disputes, scientific testing and access to genetic-parent information, but the present framework is largely reactive. It generally waits for a dispute to arise instead of preventing the initial misidentification of a child. This article has argued that parentage verification should be mandatory at birth, but that the policy must be broader than compulsory paternity testing. The appropriate model is a three-person test involving the child, the mother, and the declared or alleged father. This approach can identify baby-switching and other maternity errors that a paternal-only test cannot detect. Mandatory testing would limit privacy and bodily-integrity rights. It would therefore require clear legislation, a legitimate child-protection purpose, independent laboratories, secure data practices, strict confidentiality, and proportionate procedures. DNA results should not automatically determine legal parenthood or disrupt established families. Instead, unexpected results should trigger confirmation, counselling, and a child-centered investigation.
Parliament should amend the birth-registration and health-law framework to establish a national parentage-verification system. The system should use minimally invasive samples, retain only limited information, destroy samples after the necessary period, and prohibit unrelated use. It should provide special rules for assisted reproduction, surrogacy, adoption, rape and cases involving potential violence. The central justification is not the protection of fathers from presumed infidelity. It is the protection of children from losing their biological identity through preventable error. A child should not have to reach adulthood, experience a medical crisis or undergo a disputed paternity test before discovering that the people recorded as the child’s parents may not be the biological parents. Properly designed, mandatory parentage testing at birth would promote truth, accountability and the best interests of the child without treating biological parentage as the only form of family.
