Lying only counts if you say it out loud in court under oath.

This section shows that lying in a written declaration that the law treats as evidence is punished exactly like lying in oral testimony.

Any false statement in any document triggers this section.

Courts have clarified that the declaration must be one that some law specifically allows to be received as evidence, and the false statement must be about a fact material to that declaration's purpose.

Indian Penal Code, 1860

Section 199

repealed

False statement made in declaration which is by law receivable as evidence

Whoever, in any declaration made or subscribed by him, which declaration any Court of Justice, or any public servant or other person, is bound or authorized by law to receive as evidence of any fact, makes any statement which is false, and which he either knows or believes to be false or does not believe to be true, touching any point material to the object for which the declaration is made or used, shall be punished in the same manner as if he gave false evidence.§

Why this exists

Many laws allow people to prove facts through written declarations instead of appearing in person to give oral evidence — for example, affidavits, tax declarations, or statutory forms. Section 199 was created to ensure that this convenience is not misused. If declarations could be falsified without consequence, the entire system of accepting written statements as evidence would collapse. So the law treats a false material statement in such a declaration as seriously as false evidence given in court, and punishes it the same way (see Section 191 and 193 IPC for how 'false evidence' is defined and punished).

How courts read it

Courts have generally held that the false statement must relate to a fact that is 'material' to the purpose of the declaration — trivial or irrelevant falsehoods do not attract this section. It has also been clarified in various cases that the declaration must be one that some law specifically authorizes to be received as evidence; a random private writing does not qualify unless a statute gives it that evidentiary status. Courts have applied this section to affidavits and statutory declarations filed in judicial or quasi-judicial proceedings.
