Do Korean hospital documents need translation and notarisation for a home insurer?

Ask your insurer first — that is the correct order, and it saves the most money.

Requirements differ between insurers, and some have their own claim form with sections a doctor must complete directly. People regularly collect a full set of hospital documents, then have to return because that form was never filled in. Confirm four things before you pay for anything: whether an English medical certificate alone is enough, whether receipts and the itemised statement of charges are also required, whether a plain translation is accepted, and whether notarisation is demanded.

Korean hospitals issue more in English than people expect. An English diagnosis certificate, a treatment confirmation, an admission and discharge certificate if you were hospitalised, and a medical opinion letter if needed. Large hospitals handle this through an international healthcare centre and it can take several days, so apply with time to spare. The exception is receipts and the itemised statement of charges, which often come only in the Korean format, so those may need separate translation.

Translation and notarisation are different steps. Many insurers accept a translation alone. If notarisation is required, that is a separate process at a notary office with its own cost and timeline. Hospital records are not public documents, so an apostille cannot simply be attached — it would have to go through notarisation first, which is where the process gets complicated. Knowing exactly which level your insurer wants is what prevents wasted spending.

One practical note: documents can still be issued after treatment has finished, as in your case, but it takes longer. Next time you are at a hospital, say during the visit that you will need English documents. And request two copies rather than one, since insurers sometimes want an original.
