(1) The surviving spouse shall not have dower or curtesy in land sold but not conveyed by the deceased spouse before marriage, nor in land sold in good faith after marriage to satisfy an encumbrance created before marriage or created by deed in which the surviving spouse joined, or to satisfy a lien for the purchase money. If, however, there is a surplus of the land or proceeds of sale after satisfying the lien, surviving spouse may have dower or curtesy out of that surplus of the land or compensation out of the surplus of the proceeds, unless they were received or disposed of by the decedent in his lifetime.
(2) If the decedent held land by executory contract only, the surviving spouse shall not have dower or curtesy in the land, unless decedent owned such an equitable right at the time of his death.
