Understanding Property Disputes and DNA Evidence

Property disputes in India often arise when a family member passes away without a will, leaving heirs to prove their relationship to the deceased. In such cases, written documents like ID proofs, birth certificates, or affidavits can be forged, making DNA testing the most reliable method to establish biological kinship.

DNA testing provides objective, scientific evidence that can be used in legal proceedings to confirm or refute claims of relationship. This is particularly critical when a distant relative appears after years and claims a share in the property.

Types of DNA Tests for Property Disputes

The most common tests for property disputes are:

• Avuncular DNA Test: Determines if an individual is the biological uncle/aunt of a child, often used when the alleged parent is deceased.
• Paternity DNA Test: Confirms father-child relationship, which can be critical in inheritance claims.
• Full Sibling DNA Test: Establishes if two individuals share both parents, useful when parents are unavailable.

These tests use advanced STR (Short Tandem Repeat) profiling with 24 to 46 markers, ensuring high discrimination power and legal admissibility.

How DNA Testing Works: STR Profiling

DNA testing for relationship analysis uses STR markers, which are specific regions of DNA that vary among individuals. By comparing these markers between alleged relatives, laboratories can calculate a likelihood ratio that supports or excludes a biological relationship.

Modern laboratories, including DNA Labs India, use automated capillary electrophoresis and validated software to ensure accuracy. Each sample is tested twice to guarantee reproducibility.

Accuracy and Reliability

DNA testing is the gold standard for relationship verification. DNA Labs India guarantees:

• 99.999% probability of inclusion when a biological relationship exists.
• 100% exclusion when no biological relationship exists.

These probabilities are calculated based on population genetics databases and are widely accepted in Indian courts.
