Young couples often live together without getting married. However, there are several major legal disadvantages to this arrangement – except for the fact that in Switzerland, married couples pay more taxes than unmarried ones. There are no laws governing the partnership of unmarried couples, so there is no legal certainty about what happens if the couple separates or one partner dies. It may be helpful to draw up a common-law agreement that defines rights and obligations of both partners in the case of separation or death. Important issues to think about are rent/mortgage, children, child-support, pension funds or a will. You can find more information on such agreements on the websites listed at the end of this chapter.
