The summons/warrants/judicial processes received by MHA are forwarded to the concerned Indian Mission/ Embassy, which in turn takes up the matter with the designated Central Authority in that country. In case of MLAT countries, the manner of communication
is as laid down in the MLAT and can be either directly between MHA and the Central Authority or through diplomatic channels. The Designated Authority, after considering the request, directs its agency to serve the documents on the concerned person and the
report of the service, if any, is also received through the same channel. This is broadly the system in most countries. However, in some countries, private companies/NGOs have also been entrusted with the service of judicial papers.
In India, all requests for service of summons/notices/judicial processes on persons residing abroad should be addressed to the Under Secretary (Legal), IS-II Division, Ministry of Home Affairs, 9th Floor, LokNayakBhawan, New Delhi – 110003.
