Eternally married couples are often referred to as being "sealed" to each other. Sealed couples who keep their covenants are also promised to have their posterity sealed to them in the after life, thus the Mormon slogan "Families are Forever." The Church encourages its members to be in good standing with the Church so that they may marry in the temple.
"Cancellation of a sealing," sometimes incorrectly called a "temple divorce," is uncommon and is granted only by the highest authority in the Church. Civil divorce and marriage outside the temple is somewhat of a stigma in the Mormon culture although currently the Church itself directs its local leaders not to advise members about divorce one way or another. Local Church leaders, such as bishops, may sometimes act as marriage counselors just as clergy do in other religions.
