What do you mean by supporting documents?

Certification documents refer to documents or materials submitted in order to prove a fact or provide evidence in legal and statutory procedures. These documents and materials are usually provided by stakeholders or third parties to support or deny certain claims or statements.

Supporting documents play a key role in legal proceedings. They can provide evidence to prove the truth of a claim, and can also be used to refute the other party's claim. Proof documents can include not only written documents, but also audio, video, pictures, emails, contracts, reports, expert opinions and other forms of evidence materials.

For example, if in a criminal case, prosecutors need to prove that the defendant committed a crime at a specific time and place, they may submit a series of supporting documents including surveillance videos, witness testimony, telephone communication records and so on to support their accusations.

In civil litigation, when plaintiffs need to prove the legality of a claim or claim, they can submit supporting documents including contracts, receipts, expert testimony, patent certificates and so on to prove their rights or losses.

In the business field, supporting documents are also important. For example, when signing a cooperation agreement or purchasing a product, the buyer can ask the seller to provide relevant documents and evidence to prove the quality, authenticity and legality of the product.
