(ていせいいん)

ていせいいん
noun
correction seal; stamp used to authorize corrections on documents
1. correction seal, correction stamp
A personal seal stamped next to a correction on an official document to certify that the change was made by the signer. Used in Japanese paperwork where errors must be corrected by hand rather than rewriting the entire document.
訂正印(ていせいいん)()す。
To stamp a correction seal.
()間違(まちが)えたので訂正印(ていせいいん)必要(ひつよう)です。
I made a writing mistake, so a correction seal is needed.
契約書(けいやくしょ)誤字(ごじ)二重線(にじゅうせん)()して、その(うえ)訂正印(ていせいいん)()した。
I crossed out the typo on the contract with a double line and stamped a correction seal over it.

COMPONENTS: 訂正(ていせい) (correction) + (いん) (seal/stamp).

The standard correction process on Japanese documents:
1. Draw 二重線(にじゅうせん) (double lines) through the error
2. Write the correct text nearby
3. Stamp the 訂正印(ていせいいん) over or next to the correction

Usually the same seal used to sign the document is used as the 訂正印(ていせいいん). This practice confirms that the correction was made by the authorized person, not by someone else.

This is part of Japan's traditional seal-based paperwork system, though digital signatures are gradually reducing its use.
