Definition

口说无凭

Literally means:

verbal statement is not reliable

Actually means:

verbal statement has no binding force

It means mere verbal statement cannot be taken as sound gist. It stresses that sound evidence is to be presented to prove what is said is true; or an agreement between two parties must be bound by written documents.

口头上说的不能作为依据。强调必须提供证据来证明所说的是事实,或双方的约定必须有书面的东西作为凭证。

Example

Used as predicate, object, attributive or a minorsentence (作谓语、宾语、定语、小句)
