Divorce brings various changes that have an impact on family happiness. To create the happiness that can make families have a positive picture of their lives, support, the ability to cope with stress, and the ability of parents and children to have good relationships are needed. The main purpose of this study was to analyze the effects of family characteristics, ex-husband characteristics, ex-husband support, coping strategies, and parent-child relationship on the single parent family happiness. The design of this study was a cross-sectional study. Sampling of the study was conducted using non-probability sampling with voluntary sampling techniques. The study was conducted on single parent families with children in Indonesia who were divorced and whose ex-husband were still alive. The sample for this study was 100 families. The result showed that maternal income has a significant negative impact on coping strategies, ex-husband support has a significant positive impact on parent-child relationships, and maternal income and coping strategies have a significant positive impact on single parent family happiness. Single parent family can emerge from the crisis caused by divorce by increasing efforts to increase income, and maintaining positive communication with the ex-husband is also expected to be able to increase his affection and responsibility even though the children live with their mother.
