This is a sensitive but important area of succession law, and clients are often relieved to learn that while a Will executed by an illiterate person is not automatically invalid, Indian courts do apply heightened scrutiny to such documents, creating genuine grounds for challenge where the execution process raises legitimate concerns. Under Section 63 of the Indian Succession Act, 1925, a Will must be signed by the testator or by some other person in their presence and by their direction, and where the testator is illiterate, this typically means the Will is executed through a thumb impression rather than a signature, or through someone signing on the testator's behalf under their direction.

While illiteracy itself is not a bar to executing a valid Will, courts recognise that illiterate testators are inherently more vulnerable to being misled about the actual contents of the document they are executing, since they cannot independently read and verify what they are putting their thumb impression to. This is why Indian courts apply what is often described as a stricter standard of proof when a Will executed by an illiterate person is propounded, particularly requiring clear evidence that the contents of the Will were actually read over and properly explained to the testator, and that the testator genuinely understood and approved of those specific contents before executing the document.

Grounds for challenging such a Will typically focus on establishing that this crucial safeguard was not actually observed — evidence that the document was never properly read out to the testator, that the attesting witnesses cannot confirm the testator understood the contents, that the person who prepared the Will had a suspicious relationship with a primary beneficiary, or that the circumstances surrounding execution suggest the illiterate testator may have been misled about what they were actually signing. Courts examine these "suspicious circumstances" with particular care in illiterate testator cases, since the ordinary presumption of a testator's understanding that applies more readily to literate, educated testators requires more affirmative proof here.

Where such a Will benefits someone who was actively involved in its preparation — for instance, arranging for the document to be drafted, choosing the witnesses, or being present throughout execution — this involvement itself raises a red flag requiring the propounder to provide clear and satisfactory evidence dispelling any suspicion of undue influence or misrepresentation, a burden that becomes considerably harder to discharge when the testator's own illiteracy prevented independent verification of the document's contents.

Given how much these cases depend on carefully examining the specific circumstances of execution and the credibility of attesting witnesses, thorough investigation before deciding to challenge or defend such a Will is essential.
