An informal term sheet may show the direction of the financing but, depending on its terms, it does not prove that a drawdown-ready facility exists. A binding commitment should identify the lender, the available amount, the applicable drawdown conditions and the period for which the commitment remains valid. The SPA should tailor these requirements to the transaction.
The buyer will usually be responsible for obtaining the evidence in time. The seller may still have to cooperate with documents or approvals, for example where target-company security, shareholder resolutions or data-room information are involved. That cooperation should be stated separately rather than inferred from the financing condition.
The closing file should contain a short evidence list. It may cover the financing commitment, proof of available equity, confirmation that lender drawdown conditions have been met and approval of the payment route. The list must reflect the actual facility. A general phrase such as “financing secured” leaves too much room for interpretation.
