Parentage Anomalies

Parentage anomalies refer to unusual, disputed, or legally complex situations concerning the determination of a child’s legal parents. Traditional legal systems presumed that parentage arose naturally from marriage and biological reproduction. However, modern developments such as assisted reproductive technology (ART), surrogacy, sperm donation, adoption, same-sex parenting, posthumous conception, and disputed paternity have created anomalies where biological, social, genetic, gestational, and legal parenthood may differ.

Parentage anomalies challenge classical legal doctrines regarding legitimacy, inheritance, custody, guardianship, maintenance, succession, and identity rights. Courts worldwide increasingly emphasize the welfare of the child over rigid biological or marital presumptions.

Meaning and Nature of Parentage Anomalies

A parentage anomaly exists where:

• Legal parenthood differs from biological parenthood;
• More than two persons claim parental status;
• Genetic connection conflicts with social parenting;
• Technology creates uncertainty regarding maternity or paternity;
• Marital presumptions conflict with DNA evidence;
• A child is born after the death of a parent;
• A surrogate or donor asserts parental rights.

The law traditionally recognized:

1. Mater semper certa est — the mother is always certain;
2. Pater est quem nuptiae demonstrant — the husband of the mother is presumed to be the father.

Modern reproductive methods have weakened these assumptions.

Types of Parentage Anomalies

1. Biological vs Legal Parentage

A biological parent may not be recognized legally. For example:

• sperm donors,
• surrogate mothers,
• anonymous gamete donors.

Conversely, adoptive or intended parents may become legal parents despite lacking genetic connection.

2. Marital Presumption Conflicts

A child born during marriage is presumed legitimate even if DNA evidence suggests otherwise. This creates conflict between:

• biological truth, and
• legal stability of family relations.

Section 112 of the Indian Evidence Act embodies this presumption.

3. Surrogacy-Based Anomalies

In surrogacy:

• the gestational mother,
• genetic mother,
• intended mother,
  may all be different persons.

Courts must determine who possesses legal motherhood.

4. Assisted Reproductive Technology (ART)

ART creates situations where:

• donors contribute gametes,
• embryos are frozen,
• conception occurs after death,
• intended parents separate before birth.

Questions arise concerning inheritance, custody, and legitimacy.

5. Same-Sex and De Facto Parenthood

Modern jurisprudence increasingly recognizes:

• psychological parents,
• intended parents,
• de facto parents,
  even without biological links.

6. Posthumous Reproduction

A child conceived after a parent’s death raises issues regarding:

• succession,
• inheritance,
• legitimacy,
• social security benefits.

Legal Principles Governing Parentage Anomalies

Welfare of the Child

The paramount principle in family law is the welfare and best interests of the child. Courts often subordinate biological claims to emotional stability and social parenting.

Presumption of Legitimacy

A child born within marriage is presumed legitimate unless non-access between spouses is conclusively proved. DNA evidence alone may not always rebut this presumption.

Intent-Based Parenthood

Modern courts increasingly recognize intended parenthood, especially in ART and surrogacy arrangements.

Recognition of Social Parenthood

Some jurisdictions recognize persons who perform parental roles despite absence of biology.

Important Case Laws

1. Baby M

Facts

A surrogate mother agreed to bear a child for an infertile couple using the husband’s sperm. After birth, the surrogate refused to surrender the child.

Judgment

The New Jersey Supreme Court declared commercial surrogacy agreements against public policy but awarded custody to the intended father based on the child’s welfare.

Significance

• First major surrogacy-parentage dispute.
• Distinguished genetic motherhood from contractual parenthood.
• Established welfare principle in surrogacy conflicts.

2. ABC v. State (NCT of Delhi)

Facts

An unmarried mother sought guardianship of her child without disclosing the father’s identity.

Judgment

The Supreme Court held that an unwed mother can be sole legal guardian without requiring paternal consent.

Significance

• Expanded recognition of single-parent families.
• Reduced importance of compulsory paternal identification.
• Recognized autonomy of unmarried mothers.

3. Ivan Rathinam v. Milan Joseph (2025)

Facts

A child born during marriage was alleged to be biologically fathered by another man.

Judgment

The Supreme Court reaffirmed the strong presumption of legitimacy under Section 112 of the Indian Evidence Act and held that adultery alone does not rebut legitimacy without proof of non-access.

Significance

• Reinforced legal parentage over biological uncertainty.
• Protected stability of marital families.
• Limited misuse of DNA-based challenges.

4. Johnson v. Calvert (California, 1993)

Facts

A gestational surrogate carried a child genetically related to the intended parents.

Judgment

The California Supreme Court recognized the intended parents as legal parents because they initiated and intended the conception.

Significance

• Introduced intent-based parenthood doctrine.
• Distinguished gestational role from legal motherhood.
• Influential in ART jurisprudence.

5. Michael H. v. Gerald D. (United States Supreme Court, 1989)

Facts

A biological father sought parental rights over a child born to a married woman living with her husband.

Judgment

The Court upheld the marital presumption favoring the husband over the biological father.

Significance

• Protected family integrity.
• Limited rights of biological fathers outside marriage.
• Prioritized social stability over genetics.

6. Troxel v. Granville (United States Supreme Court, 2000)

Facts

Grandparents sought visitation rights against the wishes of the biological mother.

Judgment

The Court recognized parental autonomy as a constitutional right.

Significance

• Strengthened legal parenthood authority.
• Clarified constitutional dimensions of parent-child relations.

7. Re G (Children) (United Kingdom, 2006)

Facts

A same-sex couple disputed parental responsibility after separation.

Judgment

The House of Lords recognized the significance of psychological and social parenting.

Significance

• Expanded concept of non-biological parenthood.
• Recognized emotional caregiving relationships.

8. Jhordan C. v. Mary K. (California Court of Appeal, 1986)

Facts

A sperm donor sought parental rights after informal insemination.

Judgment

The donor was recognized as legal father because statutory donation procedures were not followed.

Significance

• Highlighted importance of statutory compliance in ART.
• Clarified donor-parent rights.

Parentage Anomalies in Indian Law

India lacks a unified parentage code. Parentage questions are governed through:

• personal laws,
• Evidence Act,
• Guardians and Wards Act,
• Juvenile Justice Act,
• Surrogacy (Regulation) Act,
• ART Act.

Indian law traditionally favors:

• legitimacy,
• marital presumption,
• social stability.

However, emerging technologies create gaps regarding:

• donor anonymity,
• same-sex parenting,
• embryo ownership,
• posthumous conception,
• multi-parent recognition.

The legal framework still struggles to reconcile:

• genetic truth,
• reproductive autonomy,
• child welfare,
• privacy rights. 

Challenges Created by Parentage Anomalies

1. Inheritance Problems

Questions arise whether ART-born or posthumously conceived children inherit property.

2. Identity Rights

Children increasingly claim the right to know genetic origins.

3. Multiple Parent Claims

Surrogacy and same-sex arrangements may involve:

• genetic parents,
• gestational parents,
• intended parents,
• social parents.

4. Privacy Concerns

Mandatory disclosure of biological parentage may violate reproductive privacy.

5. DNA Testing Conflicts

Courts must balance:

• scientific truth,
• family stability,
• legitimacy protections.

Contemporary International Trends

Modern legal systems increasingly:

• recognize intended parenthood,
• permit same-sex parent recognition,
• prioritize child welfare,
• allow de facto parenting claims,
• reduce stigma attached to illegitimacy.

The Uniform Parentage Act in the United States reflects these modern developments.

Conclusion

Parentage anomalies represent one of the most complex developments in modern family law. Scientific advancement has fragmented the traditional unity between biological, legal, and social parenthood. Courts now increasingly adopt flexible approaches focusing on:

• welfare of the child,
• family stability,
• intentional parenting,
• constitutional dignity,
• reproductive autonomy.

While traditional doctrines such as legitimacy and marital presumption remain important, modern jurisprudence recognizes that parenthood is no longer determined solely by biology. The future of parentage law lies in balancing genetics, intent, caregiving, and child welfare within a coherent legal framework.
