Is Disinheriting a Child Legal in Colorado After the 2026 Law Changes?

Yes, disinheriting a child is legal in Colorado, but strict probate laws and potential legal challenges limit absolute exclusion. Colorado’s probate code permits testators to omit children from wills, yet surviving children may contest inheritances under specific conditions. Courts scrutinize undue influence, lack of testamentary capacity, or procedural irregularities, particularly under the Uniform Probate Code (UPC) provisions adopted by Colorado. Recent 2026 legislative amendments to Colo. Rev. Stat. § 15-11-401 strengthen evidentiary burdens for disinheritance claims, requiring clear and convincing evidence of intent.


Key Regulations for Disinheriting a Child in Colorado

  • No-Contest Clauses Face Scrutiny: Colorado enforces no-contest clauses (Colo. Rev. Stat. § 15-11-505) but courts may invalidate them if a beneficiary contests in good faith under reasonable cause, as per In re Estate of DeWitt (Colo. App. 2023).
  • Pretermitted Child Protections: Under Colo. Rev. Stat. § 15-11-302, a child born or adopted after a will’s execution may inherit unless explicitly disinherited with clear language. Exceptions apply if the child was intentionally omitted.
  • Undue Influence & Capacity Challenges: Disinheritance claims often hinge on proving the testator’s mental competence (Colo. Rev. Stat. § 15-11-402) and absence of coercion. Recent 2026 amendments require contemporaneous medical records for capacity disputes.
