The list of Docs is on VFS website.
Important one is the marriage certificate , married under Special marriage Act or Hindu marriage act.
Marriage Certificate should be attested by State Home Secretary (in states its called GAD certification) and then from ministry of external affairs, New Delhi.
Once all docs are submitted, in about a month, Swiss immigration(Migrationsamt) will sent letter to the sponsor in swizterland with following additional docs.
