In England and Wales, if there are children, the survivor inherits the first £125,000 plus personal possessions plus a life interest in half the remainder; if there are no children but the deceased has surviving parents or siblings, the surviving spouse inherits the first £200,000 plus personal possessions plus half the remainder; otherwise the survivor inherits the whole estate.
The surviving spouse is paid a proportion of their deceased spouse's pension.
Women who become spouses to male peers and knights usually receive titles which last for the length of a marriage. Men who are married to women who are made dames, as well as civil partners of ennobled spouses, do not receive titles.
