The ceremonies of investiture of the Order may take place in Rome or in the localities of the local jurisdictions so long as they are held with the appropriate respect for the tradition of the order and solemnity of the ceremony of investiture. The Grand Magistery is careful to permit local custom; however, there remains a set formula for investiture that is in keeping with both history and practices set in the Constitution of 1977. When the investiture is held in the local church, the see's cathedral should always be used.

When, on occasion, the Grand Master is presiding, the local clerical officials should either join him in concelebration or attend vested in choir. If the Grand Master is present, the honor falls to him, by right of his appointment by the pontiff as Grand Master of the Order, to preside at the investiture ceremony and to personally invest each new knight and dame.
