Proof of Funds are documents issued by a financial institution, which, in the form of a written statement, demonstrate the ability of an individual or legal entity to complete a given transaction. They usually provide information such as the name of the credit institution and its address, the declaration of the requested liquidity. They are required in the case of important transactions when the seller wants to obtain proof of the buyer’s liquid availability before starting complex and expensive procedures. Relying on the declaration of a credit institution with a global presence, considered solid and reliable on the market, means ensuring not only the availability, but also that the buyer has the opportunity to legally dispose of its funds.
