You need to have your signature, or the seal and official signatures of an authority on a document, authenticated (legalised).
In accordance with the Ordinance on the Swiss Persons and Institutions Abroad, the Swiss representations abroad are among others authorized to legalise the seal and official signatures of the receiving state as well as the signatures of private persons.
Legalisation involves a written declaration by the person carrying out the legalisation (judicial or administrative authority, notary public) attesting to the authenticity of an official signature or seal on a public document, or of a private signature, so that the signature and/or seal will be accepted whenever the document is produced. The public official certifies only the authenticity of the signature and does not accept any responsibility as to the validity of the document or its content.
In this context Swiss representations have to check each request and to verify, among other things, if an agreement exists on abolishing the requirement for diplomatic or consular legalisation (apostille agreement) between the states concerned, and whether or not Swiss interests are involved.
The Swiss representation in question reserves the right to demand additional information and to reject a request for legalisation, if there is a risk of violating local legislation or of jeopardising Switzerland’s reputation.

India has acceded to The Hague Convention, Art. 12, which deals with legalisations and apostilles, in the year 2005.
Since 29.08.2007 the Ministry of External Affairs in India does apostille documents.
Documents carrying an apostille are accepted in Switzerland and therefore do not require any further legalisation by the Embassy.
