Yes, Montana permits disinheriting a child, but strict probate statutes and judicial scrutiny limit absolute testamentary freedom. A parent may exclude an heir, yet courts assess undue influence, fraud, or incapacity claims, particularly under the Uniform Probate Code (UPC) as adopted by the Montana Legislature in 2023. The 2026 amendments to MCA §72-2-114 further refine “pretermitted child” protections, requiring explicit disinheritance language to override statutory inheritance rights.
Key Regulations for Disinheriting a Child in Montana
- MCA §72-2-301 (2026 Amendments): Mandates clear, unambiguous disinheritance language in wills to override a child’s statutory share. Vague or implied exclusions risk partial intestacy rulings.
- Undue Influence Defense (MCA §72-2-802): Montana courts, per In re Estate of Bould, 2024 MT 112, invalidate disinheritance if proven by clear and convincing evidence that coercion or manipulation influenced the testator’s intent.
- Oral Disinheritance Prohibitions: MCA §72-2-502 requires testamentary disinheritance to comply with formal will execution standards (witnessed, signed, notarized). Informal statements fail to satisfy statutory validity.
Montana’s probate division enforces these rules via the Montana Supreme Court’s 2025 Probate Benchbook, which emphasizes contemporaneous documentation of disinheritance rationale. Parents should draft wills with specificity, citing MCA §72-2-114’s “pretermitted child” carve-outs, and consider affidavits of testamentary capacity to preempt challenges. Consultation with a Montana Bar Association-certified estate attorney is advised to navigate 2026 statutory refinements.
