When a person marries after making a will and the spouse survives the testator, the surviving spouse shall receive a share in the estate of the testator equal in value to that which the surviving spouse would have received if the testator had died intestate, unless:

1. (1)
   Provision has been made for, or waived by, the spouse by prenuptial or postnuptial agreement;
2. (2)
   The spouse is provided for in the will; or
3. (3)
   The will discloses an intention not to make provision for the spouse.
