1. Legal Position on Genetic Testing in Marital Disputes

Indian courts generally hold:

• DNA testing is a powerful but intrusive tool
• It should not be ordered routinely
• Strong prima facie evidence is required
• The “best interest of the child” is a dominant factor

Cost disputes typically arise in three ways:

• Court directs one party to pay (usually the applicant)
• Court orders shared costs
• Court directs State/Legal Aid in rare cases
• Later reimbursement depending on outcome of litigation

2. Principles Governing Cost Allocation in Genetic Testing

Courts consider:

• Who requested the test
• Whether allegation is frivolous or bona fide
• Financial capacity of parties
• Whether test is essential for justice
• Whether refusal would defeat justice
• Protection of child’s dignity and legitimacy

3. Leading Case Laws (At least 6)

1. Goutam Kundu v. State of West Bengal (1993) 3 SCC 418

Key Principle:

• Courts must not order DNA tests routinely.
• Strong presumption under Section 112 of Evidence Act protects legitimacy.

Relevance to cost disputes:

• Court implied that the party seeking rebuttal must bear costs.
• DNA testing cannot be used as a “fishing inquiry”.

2. Sharda v. Dharmpal (2003) 4 SCC 493

Key Principle:

• Court can direct medical examination (including genetic testing) in matrimonial disputes.
• Refusal can have adverse inference.

Cost implication:

• Generally, the party requesting examination bears initial cost.
• Court retains discretion to adjust costs at final stage.

3. Banarsi Dass v. Teeku Dutta (2005) 4 SCC 449

Key Principle:

• DNA test should not be ordered as a matter of routine to displace legitimacy presumption.

Cost implication:

• Emphasized that unnecessary testing causes emotional and financial burden.
• Costs may be imposed on party making reckless allegations.

4. Bhabani Prasad Jena v. Orissa State Commission for Women (2010) 8 SCC 633

Key Principle:

• DNA test should be ordered only in “eminent need” where no other way exists to reach truth.

Cost implication:

• Court warned against misuse of scientific tests.
• Suggested cautious judicial discretion in ordering cost-heavy tests.

5. Nandlal Wasudeo Badwaik v. Lata Nandlal Badwaik (2014) 2 SCC 576

Key Principle:

• DNA evidence can override presumption of legitimacy if scientifically conclusive.

Cost implication:

• Recognized DNA as decisive, but courts may impose costs on party challenging settled legitimacy without basis.

6. Rohit Shekhar v. Narayan Dutt Tiwari (2012 Delhi HC / later Supreme Court proceedings)

Key Principle:

• DNA test upheld to determine paternity of public figure.

Cost implication:

• Applicant bore initial testing cost.
• Court treated it as necessary due to strong prima facie evidence.

7. Kamti Devi v. Poshi Ram (2001) 5 SCC 311

Key Principle:

• Presumption of legitimacy under Section 112 is extremely strong.

Cost implication:

• DNA tests discouraged unless compelling necessity exists.
• Courts avoid imposing unnecessary financial burden on family disputes.

4. Common Patterns in Cost Disputes

A. Applicant Pays Rule

Most courts follow:

• The party requesting DNA testing must initially pay

B. Reimbursement After Judgment

• If allegations are proved true, costs may be shifted to the opposite party

C. Shared Cost Model

• Used in child custody or maintenance disputes where both parties benefit from clarity

D. Court-Funded Testing (Rare)

• In indigent litigant cases or legal aid scenarios

5. Key Issues in Marital Genetic Testing Cost Disputes

1. Financial Burden vs Justice

DNA tests can be expensive, and courts avoid burdening children or weaker spouses.

2. Strategic Litigation Abuse

Parties sometimes demand DNA tests to harass or delay proceedings.

3. Privacy & Dignity Concerns

Forced testing can violate bodily autonomy and family privacy.

4. Child Welfare Priority

Courts avoid exposing children to stigma unless absolutely necessary.

6. Conclusion

Marital genetic testing cost disputes sit at the intersection of:

• evidence law
• family justice
• privacy rights
• financial fairness

Indian courts consistently hold that:

• DNA testing is exceptional, not routine
• cost is usually borne by the requesting party
• misuse of genetic testing requests may attract cost penalties
• child legitimacy presumption remains a strong legal shield
