Right of rectification

In your request, you must indicate which data you are referring to and the correction that must be made. When necessary, you must accompany it with the documentation that justifies the inaccuracy or incomplete nature of your data. 

The entity that processes your data must communicate the rectification to each of the recipients to whom it conveys your data, unless it is impossible or requires disproportionate efforts. You can also request the identity of these recipients.
