[[caption-width-right:300:A personal seal with [[RuleOfSymbolism red]] [[ThePowerOfBlood ink]] pan]]A person receives a package or is filling out a contract. However, there's a delay, because they can't find their Personal Seal. No, not an animal.

In Chinese and Japanese law, one needs a stamp to 'sign' documents in one's name - 'signatures' as Europeans know them are an impossibility as written Chinese doesn't have an alphabet. Also called a 'chop', one's stamp must to be registered with the authorities before it is officially recognized. These stamps, referred to (by the Japanese) as ''hanko'', or ''inkan'', are used with red ink to mark a document.

The inability to locate one's ''inkan'' can be a delaying action to build tension or comedy, as appropriate. Alternatively, a person can accidentally stamp a document far more easily than they might sign one, leading to unintended results.

The practice was once common among European nobility and royalty, specifically through the use of signet rings to impress a personal seal into wax bindings on messages. (Wearing your personal seal on a ring also prevents the usual application of this trope, conveniently enough.)


[[folder: Anime & Manga ]]

* ''Anime/HandMaidMay'': Kazuya Saotome receives a package from the Cyberdyne Company, he needs to go look for his seal. When he turns around, however, the delivery person is nowhere to be found.
* ''Anime/PleaseTeacher:'' Kei Kusanagi is filling out forms to officially marry Mizuho, ostensibly to protect themselves from reprisals from his school. He is very hesitant about whether this is right to do, but a distraction takes the decision out of his hands, causing him to accidentally put his stamp on the paper.
* ''Anime/ExcelSaga'': The ColdOpening for every episode, often has a scene of Rikdo Koshi's personal seal being used to signify his 'approval' of the contents of the episode, whether this is a DatingSim, action movie, science-fiction movie, or whatever [[Creator/ShinichiWatanabe Nabeshin]] and company came up for that week.
** It also features probably the most over-the-top usage of a stamp in anime: in one of the openings, we see a huge meteorite destroying an entire city and carving an enormous crater... and the meteorite turns out to be a ''building-sized'' version of Rikdo Koshi's stamp.
* Despite driving like a maniac for her driving tests, Natsumi in ''Manga/YoureUnderArrest'' gets a driving licence anyway, since the examiner passed out during the test, conveniently letting the stamp fall on the requisite box on the form.
* Zeniba's golden seal in ''Anime/SpiritedAway'' turns out to be a major plot point, and in one DVD special the English staff talk about the addition of the word "golden" to keep the mostly young audience from mistaking it for the other type of seal that barks and dives underwater, [[ViewersAreMorons viewers being morons]] and all that.
** And since the seal is in essence Zeniba's name, [[spoiler:her sister's]] theft of it is not just robbery, but an attempt to gain magical power over her.
* A package being delivered, and the subsequent search for the seal, takes the place of the opening sequence in the first episode of ''Anime/SevenOfSeven.'' It also allows us to see the deliveryman get totally freaked out, and prove that voice actors can count to seven and deliver {{Title Drop}}s at the same time.
* In one episode of ''Anime/OccultAcademy'', Maya refuses to approve Fumiaki's proposal to allow Mikaze's shop to sell bread at the school. In fact, she throws her official seal at his head hard enough to leave a mark and enough ink for him to transfer to the paper.


[[folder: Film ]]

* In the movie "A Taxing Woman" tax evaders use all sorts tricks to hide the extra personal seals associated with their hidden bank accounts.


[[folder: Literature ]]

* Adron's personal seal is an important plot point in ''Literature/ThePhoenixGuards''.
* An example of the western version appears in Creator/DanBrown's novel ''Literature/DeceptionPoint''. [[StrawmanPolitical Evil Conservative]] [[AddedAlliterativeAppeal Senator Sedgewick Sexton]] places self adhesive wax seals on manila envelopes [[spoiler: which contain "evidence" that the president was behind a vast conspiracy to...[[ItMakesSenseInContext make it look like aliens exist]]]] to [[strike: make himself even more insufferable]] impress the journalists he plans to hand them out to.
* In ''Franchise/{{Dune}}'', the signet ring of House Atreides is brought up in multiple places. It is one of the things that Yueh makes sure heir Paul Atreides has with him when he's sent into hiding.
* ''Literature/IClaudius'' brings us this in Ancient Rome. Gnaeus Calpurnius Piso has been receiving letters from Livia, with her late husband Augustus' Imperial Seal on them. She still has free use of that seal, and notes with annoyance that Tiberius (with good reason) never shares his seal with her.
* ''Literature/ThePrinceAndThePauper''. The prince hides the Great Seal of England before "temporarily" swapping clothes with a StreetUrchin.
* Another Ancient Rome example, from Chelsea Quinn Yarbro's ''Blood Games'': Petronius asks that his seal ring be destroyed (with him watching) before he commits suicide, fearing that Nero would use it to forge evidence and invalidate his will.
* ''Literature/{{Discworld}}'': In the events of ''Discworld/{{Making Money}}'', it is revealed that Lord Vetinari's signet ring is made of a special metal, possibly an alloy, that has the unique property of absorbing light and turning it into an intense heat. He stores it in a little wooden box when not stamping paperwork with it. While one of the villains who is obsessed with imitating him has an exact replica of the ring made and wears it all the time under a glove [[spoiler: and since it's too small for him his finger turns gangrenous, fortunately Moist talks him into stepping outside into the sunlight without the glove, so the heat is intense enough to amputate and cauterize.]]


[[folder: Real Life ]]

* The significance of the physical object is hard to overstate. In real life, local managers have [[http://www.chinalawblog.com/2011/06/vie.html stolen entire companies]] by making off with the chop.
* The custom is maintained in Western nations by the seals associated with most public offices, and [[https://en.wikipedia.org/wiki/Notary_public notaries public]] in several jurisdictions have stamps and seals with their name and date of affirmation.
* For a while during the 18th century the Swedish monarchy had a personal stamp (created because it saved on time when there were too many things that legally required the king's signature). The use of it ended after the parliament confiscated it when the king refused to sign laws (it was an attempted ploy to claw back powers), declared that the previous acceptance of the stamping meant that constitutionally speaking the stamp could fill the legal role of the king, and used it to stamp laws themselves.
