In February 2006, Birdman and Lil Wayne released a mixtape, The Carter 2 Part 2: Like Father Like Son, hosted by DJ Khaled to promote the album. The mixtape had leftover tracks from Lil Wayne's album Tha Carter II and early versions of tracks that would later end up on Like Father, Like Son. According to the Cash Money's website, and an aggressive street campaign in Houston, the album was initially scheduled for release on September 26, 2006 but delays pushed the release back to October 31, 2006. Like Father, Like Son debuted at number three on the Billboard 200 chart with 176,000 copies sold in its first week. Up to July 11, 2007, it had sold 761,958 copies in the United States. In an interview, Lil Wayne said that "Army Gunz" might be the fourth single from the album. However, the song has not been released. In January 2009, Birdman said in an interview that a movie based on the title of the album and starring him and Wayne would be released in June 2009, but it was never made.
Like Father, Like Son received mostly positive reviews from music critics. Allmusic gave the album three and a half stars out of five, saying, "There's probably too much get money/stack-paper for those who want Wayne to speak on the injustices New Orleans has suffered post-Katrina, or to get to work on Tha Carter III, but that's not what Like Father, Like Son is about. This is the sure sound of Cash Money steadying the ship and getting back on course".
XXL Magazine also praised the album, giving it four stars out of five (XL), saying "With solid production throughout, Wayne's ever-evolving sentence structure and Baby's uncanny swagger, Like Father, Like Son falters only in the diversity department. Over the course of the project's 20 tracks, continued references to their dope-dealing pasts ("1st Key" and "Over Here Hustlin'") begin to dilute what otherwise is a solid project that ushers in a new Cash Money dynasty."
On October 2009, Birdman, Lil wane, Cash Money Records and various music distribution outlets were sued for copyright infringement by Thomas Marasciullo, who claimed his voice was used without permission. The rappers asked him to record some "Italian-styled spoken word recordings" in 2006. The lyrics were allegedly used on "Respect" and other tracks from Like Father, Like Son and Birdman's 5 * Stunna.
