Article 5

  1. Every player wishing to play as an amateur or non-amateur in any competition organised or recognised by a national association shall be registered with that association.
  2. Players may only be registered to play with a national association during one of two registration periods per year, as laid down by the national association for this purpose, with a limit of one transfer of registration per player in the same sports season in a period of 12 months. One of these periods ('registration periods') is fixed for the end of the season and another period for the middle of the season.
  3. National associations can only register players coming from another association subsequent to the receipt of (i) a certificate of transfer of registration from that other association (hereunder referred to as the 'international registration transfer certificate') and (ii), in the case of a non-amateur, a copy of the player's contract with his new club.
  4. Extracts from this register shall, upon demand, be made available to FIFA.
  5. The regulations governing the application of these regulations (hereunder referred to as the Application Regulations) will set out the rules governing the registration periods and the information to be contained in the register in more detail.
