This is supported by the case law that a « counterpart » is in itself a separate act which, together with the principal and all the other counterparties, constitutes an act. This means that a document purported to be a valid counterpart must be properly executed by the party, which would probably not be the case if the two signatories signed separate copies. In short, contracts and deeds can usually be signed nearby. The absence of a specific counter-value clause should not affect the validity of an act when an act has been performed in return. Such a clause may, however, help prevent another party from arguing that an agreement is not binding. They could argue that in the absence of a counter-clause, they did not know that they had entered into a binding contract by signing an agreement not signed by the other parties. Counter-parties are generally used when contract signatories are in different locations and contracts should include clauses allowing the use of intercom points. This clause generally states that each correspondence, signed, « must be considered original » and that all the considerations combined are a document. If you sign a private contract between two parties, you can agree on the types of acceptable signatures. Make this contract in writing so that you can bring it to justice if necessary. If your contract or agreement is to be registered with a court, you will probably need to have original signed documents as consideration. Counterparty clauses are often used when the parties to an agreement execute separate copies of the agreement. They are mainly used: in recent years, more and more people are using electronic signatures (e-signatures) to sign contractors.
Different jurisdictions have addresses in which an email can be used as a binding contract. In short, an email may be a handwriting capable of being a contract if signed by the party, or someone who has the right to engage the party and who contains the terms of the contract. Of course, the signature required on the email must be a valid electronic signature. If you are wondering about the legality of an electronic signature in a particular contract, look first at the contract and the counterparty clause.
