Copyrights can be acquired without formalities, as a direct result of the creation of the artwork. Your creation is therefore protected as soon as you create it. However, in case of dispute, you must be able to prove the exact date when your work was created.
Whether you're an artist, painter, sculptor or photographer, you must be able to establish that you are the actual author of your artwork, the date on which you created it and its originality.
Send yourself a registered mailThe cheapest option is to send yourself a registered letter which contains a copy of the artwork you created. The acknowledgement of receipt sticker should cover the flap of the envelope to prevent the contents of the envelope from being tampered with. It is important not to unseal the envelope or to do so only in front of an official bailiff or magistrate.
Deposit of a Soleau envelopeA Soleau envelope (bearing the name of its inventor) costs 15 euros and can be collected from the INPI. This is a double envelope in which you can insert the document you would like to protect. However, the envelope cannot contain a CD or more than 7 pages.
A number is laser cut on the envelope and one of the flaps is returned to you. The INPI keeps the other one for a period of 5 years, renewable upon payment. Beyond this period, the second flap will also be sent back to you. It won't lose its probative value if it is kept intact.

Deposit with a notary or bailiffThis is the most effective method of deposit because it is made with a government official. The deposits will be indisputable until a procedure of forgery is initiated. If the deposit is kept indefinitely, the process can be quite expensive (between 200 and 300 euros).
