A contract by correspondence is concluded at the time and place where you, having received the offer, reply by accepting it (art. 24). What counts, therefore, is not the receipt of your reply by the other party, but the moment when you reply favourably.
An important point about the time limit:
- If the offer sets a time limit for acceptance, the person who made it remains bound until the expiry of that limit; he is released if your acceptance does not reach him within the set time limit (art. 29).
- If the offer sets no time limit, its author remains bound until the moment when a reply, sent within a reasonable moral time, should normally have reached him (art. 30).
Be careful, too, about the form of your reply: a conditional or restrictive reply does not amount to acceptance. It is equivalent to a refusal accompanied by a new proposal (art. 27). Conversely, your reply conforms to the offer if you simply say that you accept, or if you perform the contract without making any reservation (art. 28).
In plain terms: reply clearly "yes", within the time limit, and the contract is formed.
