If I die, my spouse automatically inherits everything
FALSE: If you haven’t made a valid Will, you’re said to have ‘died intestate’ and there is a set of rules that come into play to determine who inherits. These are ‘the rules of intestacy’, and they state that a spouse or civil partner inherits all personal possessions and the first £250,000 of the deceased partner’s money if they were married at the time of death. (Children or grandchildren will also get a share if the estate was worth more than £250,000.)
However, if you do write a Will, your spouse can inherit as much or as little of your property as you choose.
