B-SAD is a Portuguese football club from Lisbon founded on 30 June 2018 as an independent entity. A rebel offshoot of Clube de Futebol Os Belenenses, they played four seasons in the Primeira Liga, being relegated to the Liga Portugal 2 for 2022–23. Before changing their name, after the 2021–22 season, they were referred to as Belenenses SAD, officially Os Belenenses – Sociedade Desportiva de Futebol, SAD. Background and legal status Historic football club C.F. Os Belenenses created its SAD (Sociedade Anónima Desportiva - Public limited sports company) on 1 July 1999, to run its professional football section. In 2012, with both club and SAD facing enormous financial troubles, club members voted to sell 51% of its SAD to an investor, Codecity, led by Rui Pedro Soares. Added to the stock purchase, a parasocial deal was struck where the founding club could keep special rights, such as veto power over certain SAD decisions and the power to buy its stock back. Also a protocol was agreed upon that would regulate relations between Club and SAD. The club would keep 10% of SAD stocks. Meanwhile, Codecity terminated the parasocial deal, alleging contractual violations by the Club. In 2017, the Court of Arbitration for Sport deemed the termination of the deal valid, ending the possibility of the Club being able to reacquire the 51% of SAD stocks, in order to regain control of its professional football section. With tensions mounting between Club and SAD, the protocol that regulated relations between both entities expired on 30 June 2018, ceasing any relationship between both parties. This included the use of Estádio do Restelo (property of the Club) by the SAD's professional football team. Thus was born B-SAD as an autonomous football club, founded on 1 July 2018, after the secession of the SAD from the club. They joined the Lisbon Football Association as member number 1198 (the original Belenenses is member number 64). Belenenses' historic achievements, such as the victories in the 1945–46 Campeonato Nacional, its 3 Taças de Portugal and 3 Campeonatos de Portugal, solely belong to the Club, since they were won before the creation of the SAD in 1999. The Club created its own football team that started playing in the Lisbon FA regional leagues from 2018–19 season. B-SAD meanwhile claimed the place of the Club in the Primeira Liga. Given that Estádio do Restelo was property of the Club, B-SAD
