For U.S. law, see: http://www.copyright.gov/title17/92chap4.html#412

The basic rule is that for an unpublished work you may not recover statutory or attorney's fees for any infringement which occurs before the effective registration date. For a published work, you may not recover for infringement which occurs between the publication date and the effective registration date unless the copyright is registered within three months of publication.
