There are many clients and colleagues who have asked us for this formula. What is it for, what does it mean if it is used and for what purpose? Is it an unnecessary formula or is it something really important? IN WITNESS WHEREOF has led each party to implement this agreement by its duly accredited representative. Have you ever found this expression in a legal document? I`m sure you will, won`t you? Especially in contracts. But do you know what it really means and why it is formulated in this way?

The doublet means, among other things, the signing, signature or conclusion of a contract or other document, so that it can be translated into one of these verbs. In this way, the contract refers to a formal and binding agreement which, for its validity, requires the existence of certain elements (offer – acceptance – consideration), whereas the agreement would be before the formalization (execution) of the contract.
