Excerpt from the Mormon Newsroom, Topic – Polygamy: 1
“Today, the practice of polygamy is strictly prohibited in the Church, as it has been for over a century. Polygamy — or more correctly polygyny, the marriage of more than one woman to the same man — was a part of the teachings of The Church of Jesus Christ of Latter-day Saints for a half-century. The practice began during the lifetime of Joseph Smith but became publicly and widely known during the time of Brigham Young.”
From the LDS Church’s ‘Handbook 1: Stake Presidents and Bishops’, 2010, 3.6.1: 2
“Sealing of Living Members after a Spouse’s Death
Women. A living woman may be sealed to only one husband.
Men. If a husband and wife have been sealed and the wife dies, the man may have another woman sealed to him if she is not already sealed to another man. In this circumstance, the man does not need a sealing clearance from the First Presidency unless he was divorced from his previous wife before she died (see the previous heading for the policy in cases of divorce).”
