Marital separation is a research area that explores the process and impact of couples who decide to live apart but remain legally married. This can occur as a prelude to divorce, as a trial separation, or as a way to address marital issues without ending the relationship. Research in this area may focus on the reasons for separation, the emotional and psychological effects on individuals and families, the communication and conflict resolution strategies employed during separation, and the decision-making process regarding reconciliation or divorce. Studies may also examine the legal and financial implications of marital separation, as well as the factors that contribute to successful outcomes or difficulties in the separation process.
