Charges could soon be laid against The Courier-Mail for allegedly breaching the Family Law Act during its coverage of a custody battle over four Italian sisters.

The Australian Federal Police launched an investigation into the Queensland newspaper after it last year published the names and photographs of the sisters at the centre of the international dispute.

The Courier-Mail's coverage of the custody dispute on May 15 and 16, 2012.

After eight months, the AFP has handed a brief of evidence to the Commonwealth Director of Public Prosecutions and the two bodies will work together to decide if charges should be laid. One insider said it was "highly likely".

Photos of the girls were published on the front page and inside The Courier-Mail on May 15 and 16 last year, prompting a complaint from the Chief Justice of the Family Court.
