This chapter looks at forms of uncertainty that occur at different stages of married life. A central question here is what does uncertainty produce? The chapter focuses partly on Malay protagonists and on two particularly fragile moments in Malay marriage: during betrothal and, counterintuitively, much later on, after several decades, when one might expect marriages to be highly stable. The former was a pattern familiar from earlier research. But some older Malay women spoke of a more recent trend – for husbands of many years to marry a younger woman polygamously. Meanwhile, other, non-Malay, couples have adopted unconventional living arrangements or have taken unusual paths to suit their particular circumstances. In considering how different kinds of marital uncertainty play out, the significance of expectations about marriage and the registers of temporality through which they are calibrated and recalibrated are illuminated. The force of unanticipated events stimulates the reflection of protagonists and their consociates – as readers may recognise from their own experiences – reformulating ideas of what is appropriate or acceptable behaviour, and precipitating new ethical stances.
