Embassy legalisation for use in Indonesia
Embassy legalisation is generally not required for documents used in Indonesia. Indonesia accepts a simpler single-step certification instead, so consular legalization for Indonesia forms no part of this route and nothing needs to travel on to a mission once the British office has finished with it.
That single sentence saves most readers their first week. The habit is to open by looking for the destination's consular section, its appointment system and its fee schedule, and for this destination not one of those three things exists to be found.
Indonesia consular requirements
There is no consular stage to describe here. Embassy attestation for Indonesia forms no part of what an Indonesian office asks of a British document, and a search for the forms, opening hours and appointment slots that would go with one turns up nothing useful, because there is nothing there to be turned up.
The practical effect is that the work starts somewhere else entirely. Instead of a diary and a queue, the opening question is which piece of paper is going to travel, and that question can be answered on the same day it is first asked.
The Sheffield → Indonesia route step by step
To legalize documents for Indonesia, begin at whichever body issued the paper. Sheffield Register Office at the Town Hall, Pinstone Street, Sheffield S1 2HH issues fresh certified copies of birth, marriage and death entries, and a copy travels in place of the certificate a household keeps. The FCDO Legalisation Office then adds the certification, working by post from PO Box 6255, Milton Keynes MK10 1XX.
After that the file is done and there is nowhere else for it to go. Document legalization for Indonesia has one official desk in it rather than three, and the paper that comes back is complete as it stands rather than being groundwork for something else that follows.
Cost & timing for this route
An official fee applies to the certification, and there is no consular fee behind it because there is no consular stage to levy one. Standard handling runs 7–10 business days and the express route 2–3 business days, both measured at the desk rather than door to door.
The timing is unusually easy to plan for that reason. One desk with a published window and two postal legs is the whole of it, and a reader who had set aside weeks for a mission's diary can take those weeks straight back out of the plan.
Destination-specific requirements
Embassy legalization for Indonesia from Sheffield is therefore a phrase without a matching process behind it. What an Indonesian office wants is a British document carrying the certification the FCDO Legalisation Office adds, presented complete, with the sheets still fastened together exactly as they were sent back.
Keeping that bundle intact matters more than it sounds. The certification refers to the sheet beneath it, so the returned set is handed over as one item, and a page pulled out for scanning breaks the very link it was added to create.
