The Roommate Agreement



 was written by Sheldon Cooper and was signed by Leonard Hofstadter when they became roommates. These events were shown during a flashback in The Staircase Implementation. Sheldon starts mentioning paragraphs from the Roommate Agreement in the episode The Cooper-Nowitzki Theorem and continues to do so through out the series usually during someone's violation.

Sheldon revamped the agreement to better favor himself in The Agreement Dissection. The new version was only agreed upon via blackmail as Sheldon set up a one minute timer which would have emailed information to Priya Koothrappali's parents regarding her relationship with Leonard.

Breaks of the Roommate Agreement

 * Sheldon frequently accuses Leonard of potential breaks of the roommate agreement or uses the agreement to enforce his will ( S2 Ep6 )( S2 Ep10  )( S3 Ep15 )( S3 Ep22 )
 * Although pets are banned under the roommate agreement (see Unspecified Clauses), in Season 4, Sheldon bought a bunch of cats after he and Amy went their separate ways. Leonard doesn't seem to catch this as a break of the roommate agreement. However, Sheldon wasn't entirely in his right mind following the breakup, and in fact, gave the cats away after reuniting with Amy. Similarly, Sheldon was emotionally unwell when he brought goldfish into the apartment in order to make them glow in the dark (and succeeded) though this would not count as as breach as they where Goldfish night lights, dubbing them a service animal.

Trivia

 * The Agreement says nothing about regulations when one of them gets a girlfriend, because both never thought it would happen. (S3 Ep15) However, they both did. (Leonard has romantic relations with Penny & Priya, while Sheldon has officially declared Amy his girlfriend in a separate agreement ).

Controversial Clauses
Sheldon states that the Roommate Agreement contains a clause that all ties will be settled by him. Leonard affirmed this, but underlined that he didn’t sign that clause, while Sheldon argues that whilst Leonard disagreed, he agreed, so, the tie clause is made valid. (S3 Ep22)
