The current study consists of a systematic review of previous studies. For this purpose, 95 articles were downloaded related to the concept of current research. After screening the data, it was decided to include 60 articles for review and extract the results. Further, this study tries to find out the validity and extension of DTPB (decomposed theory of planned behaviour). Therefore, attitude, subjective norm, and perceived behavioral control were taken as variables. Furthermore, it is found that attitude with dimensions such as perceived usefulness, knowledge, and perceived religiosity has a positive link with the intention to purchase a family takaful. Whereas second proposition is also accepted on the basis of a review of previous studies that subjective norm with its dimension of media referent and word of mouth has a positive and significant relationship with the intention to purchase a family takaful. In this study perceived behavioral control with dimensions such as resource facilities and financial self-efficacy has a positive link with intention to purchase a family takaful. The results of this study are identical to DTPB theory although the dimensions of some variables are modified to the extent D.T.P.B theory. Further, this study has some limitations and implications, such as the systemic review of the literature related to family takaful and purchase intentions. Limited articles from specific journals are selected and the articles are in different contexts of countries. The practical implications of the current study provide guidance on takaful which is an important tool for managing risk, both for individuals and
