Omitted or Pretermitted Children Under Wills in Wyoming

Short answer Wyoming's current probate title states no general omitted-child share formula. A will may dispose of property subject to surviving children's rights, while the intestacy chapter distributes property left undisposed of by will. Separate provisions protect a surviving minor child's support and exempt property; they do not calculate an intestate-equivalent share for omission from a will.

When a will omits a child

Wyo. Stat. § 2-6-101 permits a will to dispose of property, “subject to the rights of the surviving spouse and children.” Title 2's will provisions do not turn that clause into a general omitted-child share calculation. Under § 2-4-101(a), intestate descent applies to property left undisposed of. The will's expressed intention controls its dispositions under § 2-6-105.

A surviving minor child may have separate protection: § 2-7-501(a) permits possession of the homestead and household items pending administration and a court-allowed reasonable support provision. Wyo. Stat. § 2-7-504 directs a set-aside of exempt property to the spouse, or if none, the minor children. Those are distinct from a missing will-gift formula.

What trips people up

The posthumous-person rule in § 2-4-103 says someone conceived before death but born afterward inherits as if born during the decedent's lifetime. It does not state that a will is displaced whenever it omits that person. Likewise, § 2-4-108(a)'s lifetime-gift advancement calculation applies when a person dies intestate.

Common questions

Does a posthumous birth itself create an omitted-child share? Section 2-4-103 protects inheritance status, but states no share to take away from dispositions in a will.

Can a will leave property to a trust? Wyo. Stat. § 2-6-103 permits a devise to the trustee of an existing written trust identified in the will; it does not set an omitted-child share for that trust.
