He married Tekla Anna Wołłowicz in 1626, Katarzyna Eugenia Tyszkiewicz in 1639 and Lucricia Marie Strozzi in October, 1642 in Warsaw. His marriage to Katarzyna Eugenia Tyszkiewicz, widow of Konstanty Wiśniowiecki's son, led to the conflict between Aleksander Ludwik Radziwłł and Jeremi Wiśniowiecki over the inheritance of Konstanty. Eventually, Katarzyna defected to Jeremi's side and divorced Aleksander, who was forced to give up his claims.

He kept away from politics during the reign of Sigismund III Vasa, but supported Władysław IV Vasa, in his election in 1632. However towards the end of his life he distanced himself from Władysław, by opposing his plans of war with Ottomans.
