Montana estate planning
Montana will, trust & power-of-attorney requirements
Montana sets its own rules for how an instrument must be signed and witnessed, whether it needs a notary, and how estates are taxed. The requirements below are drawn from the same attorney crafted & attorney verified Montana rule set Estateur drafts against — every Montana will, revocable living trust, and power of attorney is generated to these formalities and validated against them before delivery.

How to make a valid will in Montana
A Montana will must be in writing and signed by the testator in front of two witnesses. Notarization is not required for the will to be valid, but a self-proving affidavit — which is notarized — makes probate easier by removing the need for the attesting witnesses to testify later. Montana recognizes handwritten (holographic) wills, but a properly witnessed will is far stronger and easier to probate.
Spousal protection. Up to 50% of marital-property portion of augmented estate, sliding scale (MCA 72-2-232). A will cannot fully disinherit a surviving spouse in most states — Estateur's intake flags an elective-share exposure on the draft.
Living trusts & avoiding probate in Montana
A will still has to pass through Montana probate — a public, court-supervised process — before assets reach the beneficiaries. A revocable living trust holds assets during life and transfers them at death without probate, which is usually faster and stays private. Whether a trust is warranted turns on the client’s real property, the size and complexity of the estate, and the planning objectives.
Estateur drafts either structure on your instruction, and every trust-based matter generates the pour-over will as a companion instrument, with the plan-level consistency checks run across the set.
Powers of attorney & healthcare directives in Montana
A financial power of attorney in Montana must be acknowledged before a notary to be effective. (MCA 72-31-305)
A Montana healthcare directive must be signed before two qualified witnesses. (MCA 50-9-103)
A complete plan also includes a HIPAA authorization so the healthcare agent can actually obtain the client's medical information. Estateur drafts each of these to Montana's signing rules and generates the matching execution instructions.
Montana estate & inheritance tax
Montana has no state estate tax and no state inheritance tax. Only the federal estate tax can apply, and it affects very few estates.
Estate-tax exemption amounts are 2025 figures and change annually. Confirm current thresholds with the Montana department of revenue.

Montana estate planning: common questions
- How many witnesses does a will require in Montana?
- Montana requires two witnesses to the testator's signature (MCA 72-2-522). A notarized self-proving affidavit is optional but recommended — it admits the will to probate without witness testimony. Montana also recognizes handwritten (holographic) wills, though a properly attested will is far stronger.
- Does Montana permit electronic wills?
- No. Montana has not adopted an electronic-wills statute, so a will must be executed on paper under the state's ordinary formalities. Estateur's Montana execution instructions reflect that.
- What are the signing requirements for a financial power of attorney in Montana?
- A financial power of attorney in Montana must be acknowledged before a notary to be effective. (MCA 72-31-305)
- Does Montana have an estate tax or inheritance tax?
- Montana has no state estate tax and no state inheritance tax. Only the federal estate tax can apply, and it affects very few estates.
- How does Estateur handle Montana-specific requirements?
- Estateur drafts each instrument against Montana's attorney crafted & attorney verified rule set, including execution formalities, mandatory and prohibited clauses, and statutory citations. It then runs required checks before delivery. Every Montana document includes a matching execution checklist. Estateur is a self-help document preparation service, not a law firm.
