Why expats and foreign firms choose iVC for Japanese legal translation
Highest liability class — a single mistranslated clause in a THB-million contract can trigger cross-border litigation. Translators must hold a legal background or work in tandem with a native-speaking lawyer. iVC matches every japanese legal project with a translator who holds subject-matter credentials and works inside a CAT environment (Trados Studio 2024 + MultiTerm) so terminology is consistent across every file in your programme. Each deliverable passes a documented four-eyes review — translator → subject editor → proofreader → QA sign-off — before it goes near a notary or an embassy counter. Foreign investors need clean legal translations for BOI applications, Amity Treaty filings, and share-transfer documentation.

Terminology traps in Japanese legal translation
A single mistranslated term in a legal deliverable can void an insurance claim, invalidate a contract clause, or block a regulatory submission. The glossary below is the baseline our Japanese legal translators lock into every project's termbase:
- ▸契約書 (Keiyakusho) — Contract / Agreement (Standard sale, service, or employment contract)
- ▸委任状 (Ininjō) — Power of Attorney (POA)
- ▸登記簿謄本 (Tōkibō Tōhon) — Certified copy of company register
- ▸公正証書 (Kōsei Shōsho) — Notarial deed
- ▸判決 (Hanketsu) — Court judgment (Requires a legal translator with Japanese-court experience)

Do you use AI or machine translation?
Not for legal content — the risk profile is too high. We use CAT tools (Trados) for consistency, but every sentence is produced or reviewed by a human specialist translator. MT post-editing is available only when the client requests it and only for internal drafts.
How do I send the source documents?
Colour PDF scans by email, LINE, or Google Drive; hard copies to our Lat Phrao 95 office; or ProtonDrive end-to-end encrypted upload for highly sensitive files.
Can you deliver in 24 hours?
Yes for 1–5 pages at +50%. Larger urgent projects need a short scoping call so we can assemble the right team without breaking QA.
How many revisions are included?
Unlimited revisions for genuine translation errors. Client style-preference edits after sign-off are billed at 30% of the original per-page rate.
