Mafia membership is a permanent, non-transferable bond that cannot be terminated.

Evidence

Finally, the property rights of the family include rights over members themselves. How else could one interpret the rule which decrees that members are not allowed to change families but are tied to the family that initiated them (TB: I, 126)? Each family has its own members and is not supposed to poach those of another. Correspondingly, each member has his own family and is not supposed to interfere with other families. According to Tommaso Buscetta: “Once the oath is taken, the man of honor will remain one all his life. It is impossible to terminate this status spontaneously, unless there are justifiable motives… Wherever he is and whatever he does, the man of honor never ceases to belong to the family” (TB: 23-24). — Diego Gambetta, The Sicilian Mafia The Business of…, 328
