While there has been increasing research interest in the Islamic estate planning areas, few studies have yielded detailed insights into the views and factors which motivate consumer in patronising wasiyyah. The qualitative research describes in this paper aimed to explore the views of Malaysian Muslims towards wasiyyah and to identify the reason that motivate Muslims in writing wasiyyah services in Malaysia. The study was framed by using the Self-Determination Theory (SDT) approach. This enabled us to examine the factors of motivation in two ways: intrinsic motivation and extrinsic motivation. The research participants for the current study were recruited on the basis of a consumer who has made wasiyyah in any institutions in Malaysia. Data analysis was undertaken using a framework approach and was informed by SDT. Consumers’ intrinsic motivation has been identified into three items: interest, religion, and family. Meanwhile, consumers’ extrinsic motivation also come out with three items: future rewards, awareness, and financial management. All these factors are the main thing that should be focused among marketers to come out with better strategies to increase more Muslims in writing wasiyyah as well as to avoid rising inward in frozen assets. Therefore, more research is required to examine how to raise awareness of Malaysian Muslims on the importance of wasiyyah.
