Remarriage is a marriage that takes place after a previous marital union has ended, as through divorce or widowhood.Some individuals are more likely to remarry than others; the likelihood can differ based on previous relationship status (e.g. divorced vs. widowed), level of interest in establishing a new romantic relationship, gender, culture, and age among other factors. Those who choose not to remarry may prefer alternative arrangements like cohabitation or living apart together.Remarriage also provides mental and physical health benefits. However, although remarried individuals tend to have better health than individuals who do not repartner, they still generally have worse health than individuals who have remained continuously married. Remarriage is addressed differently in various religions and denominations of those religions. Someone who repeatedly remarries is referred to as a serial wedder.
