Forensic Psychiatry: Testamentary Capacity
Legal Competence to Execute a Will
Testamentary capacity is the legal mental ability of an individual (the testator) to make a valid will. Unlike general competency, this is task-specific and relates specifically to the act of disposing of one’s property after death.
1. The Banks v. Goodfellow Criteria (Standard)
To have capacity, the testator must:
- Understand the nature of the act: Know they are making a will.
- Know the nature and extent of their property: Have a general understanding of what they own.
- Identify natural beneficiaries: Recognize those to whom they might naturally leave property (e.g., spouse, children).
- Be free from “insane delusions”: Ensure that the distribution of property is not influenced by a mental disorder that distorts their judgment regarding beneficiaries.
2. Medico-Legal Assessment
| Assessment Factor | Forensic Focus |
|---|---|
| Cognitive State | Presence of dementia, delirium, or cognitive impairment. |
| Psychiatric State | Presence of delusions, psychosis, or severe depression. |
| Temporal Context | Did the testator have capacity at the exact moment the will was signed? (Lucid interval). |
3. NEET PG High-Yield Pearls
- Dynamic Capacity: Capacity is not static. A person may lack general capacity (e.g., cannot manage finances) but still retain testamentary capacity.
- Undue Influence: A separate legal ground for challenging a will, distinct from lack of capacity, where someone else coerces the testator.
- Retrospective Evaluation: Forensic psychiatrists are often asked to evaluate capacity retrospectively based on medical records, witness statements, and prior cognitive testing.
- Age Threshold: Generally 18 years, though local laws vary regarding minors and emancipated youth.
