Abstract
This research was aimed to find the use code switching in bilingual family, the reason motivating the family members do code switching in daily conversation and to find out the types of code switching. In collecting the data, I used a recording device to record the family conversation in natural setting. The collected data from the recorded conversation are transcribed into written form then I classified them into each type of code switching. Based on the data finding, I found that the factor triggering code switching in the family are, the speakers, interlocutors, and the presence of 3rd person. Moreover, there are three types of code switching found in the family conversation namely, tag switches, inter-sentential code switching, and intra-sentential code switching.
