What kind of document is the content certification?

Content certification is a postal service that allows the post office to prove who sent a document to whom, when, and with what content. Although the document itself does not have legal force, it is used to prevent rebuttals such as "I never heard that" and to confirm the timing of exemption, termination, and claims.

In practice, it is used when payment is behind, when terminating a lease or notifying of refusal to renew, when requesting repairs for defects, or when notifying that a bond has been transferred. It is also used as a means to suspend the statute of limitations, but its effect is maintained only when follow-up procedures, such as a lawsuit, are taken within 6 months.

Please gather supporting materials before sending. If the price is a contract and bill · transaction statementA. If it is a lease, a contract and deposit details are required. If the facts written in the document are inconsistent with the data, it will be at a disadvantage.

Formatting

The text is one A4 page. The recipient, sender and subject are at the top, followed by facts and requirements, deadline for performance, and actions in case of non-compliance. If you download it in Word, a sheet of shipping procedure instructions will be attached at the end.

Things you can easily miss when writing

  1. 01Please write down only the date and amount of facts. Mixing emotions and guesses reduces the trustworthiness of the entire document.
  2. 02Narrow your requirements down to one. If multiple demands are mixed, none of them will be fulfilled by the other party.
  3. 03Put a date on the deadline for performance. “As soon as possible” is not a deadline.
  4. 04Print 3 copies, go to the post office, and apply for proof of delivery.
  5. 05After sending, be sure to schedule a follow-up process. If left untreated, it will not remain at peak effectiveness.

Frequently Asked Questions

Does the content certification have legal effect?

The document itself does not force the other party to do anything. However, because the information about when and what information was notified remains public, it becomes important evidence in later lawsuits or payment orders. Its original role is to determine the timing of expressions of intent that need to be reached, such as superannuation, termination, and claims.

How do I send it?

Print three copies of the same document and take them to the post office. One copy is sent to the other party, one copy is kept by the post office, and one copy is kept by the sender. You can also apply online at the Internet Post Office. If you want to be sure of delivery, please apply for a proof of delivery.

How many sheets are there?

There is no length limit, but the longer it is, the more likely it is to be unreadable and prone to mistakes. It is most effective to organize the facts and requirements on one A4 page. Do not attach any materials such as a copy of the contract, just mention it in the document.

Can I add some emotional expressions?

Don't put it in. Phrases that can be read as threats actually work against you. Saying "I will take legal action" is enough, and expressions that attack the other person's personality or unfounded claims can lead to defamation issues.

What if I don’t know the address?

The proof of contents must be sent to the address, so an address is required. If you are a business, use the address on your business registration or register, and if you are an individual, use the address written on the contract. If it is returned, keep a record of it as well.

Is what I write saved on the server?

It is not saved. The information you enter and the uploaded stamp photo are processed only within the browser, and PDF and Word files are also created on the user's device.

This is general information for guidance purposes only, and the effect of suspending the statute of limitations or terminating the contract will vary depending on the individual case. If the amount is large or the matter will lead to litigation, have a lawyer review it before sending it.

Content Certification Reviews

These are stories left by those who actually wrote and submitted the content certification. It contains notes on areas where you got stuck while writing or the results after submission, so it is often more helpful than a guide for first-time users.
