Colorado Law · Spouses

In Colorado, a will cannot simply write a husband or wife out of the estate. The elective share gives a surviving spouse the right to claim a protected portion — if they act in time.

The will is read, and a widow who spent decades building a life with her husband learns she has been left almost nothing — the estate directed instead to children from his first marriage, or to a trust she's never seen. Her first assumption is that nothing can be done; wills are wills. In Colorado, that assumption is wrong. The law refuses to let marriage end in total disinheritance.

The tool is called the elective share: a surviving spouse's statutory right to claim a protected portion of the deceased spouse's estate, regardless of what the will says. It reflects a simple judgment embedded in Colorado law — that marriage is an economic partnership, and a surviving partner should not be left with nothing from it.

Whiteford's Colorado team advises on the elective share from every direction: surviving spouses deciding whether to elect, families responding to an election, and couples planning ahead so the question never becomes a fight. Here's how the protection works in plain English.

How the elective share works

The core of the elective share is a choice. A surviving spouse can accept whatever the will provides — or elect against the will and take the share the law provides instead. In Colorado, that protected share is calculated on a sliding scale that grows with the length of the marriage: a brief marriage yields a modest protected share, while a long marriage yields a substantially larger one, reflecting the deepening of the economic partnership over time. The specific fractions and mechanics are set by statute, and the vetted law summary on this page carries the current details.

Just as important is what the share is calculated against. It isn't limited to the probate estate — the assets passing under the will. Colorado uses an augmented-estate concept that sweeps in a broader picture of the couple's wealth, including many assets that pass outside the will and certain transfers made before death. That breadth is deliberate: it prevents a spouse from being disinherited through clever titling rather than candid terms.

When elective-share questions arise

Elective-share disputes cluster around recognizable situations, and almost all of them involve remarriage, late-life marriage, or blended families — circumstances where a decedent's loyalty was genuinely divided between a spouse and children from an earlier chapter. Sometimes the disinheritance was a considered decision; sometimes it reflects an old will never updated for a new marriage; occasionally it signals something darker, like influence over a declining spouse.

These are the fact patterns we see most often. If yours resembles one of them, the essential first step is the same: get the estate's full picture and your options mapped before positions harden.

  • A will that leaves the surviving spouse little or nothing, usually favoring children from a prior marriage
  • An estate arranged so most wealth passes outside the will — trusts, joint accounts, beneficiary designations — leaving the spouse a share of very little
  • A late-in-life marriage where the estate plan was never updated to reflect the new spouse at all
  • A marital agreement in which a spouse may have waived elective-share rights, raising questions about the waiver's validity
  • An election filed against an estate, leaving the family and personal representative to respond and recalculate distributions

Deciding whether to elect — and planning so no one has to

For a surviving spouse, election is a genuine decision, not a reflex. It requires comparing what the will and non-probate transfers already provide against what the elective share would yield from the augmented estate — an analysis that demands a real accounting of assets on both sides of the ledger. It also carries family consequences, since an election reshapes what everyone else receives. And critically, the window to elect is limited; like other contest windows in Colorado, it can be short, so the analysis should start promptly even if the decision deserves care.

For couples planning ahead, the elective share is a design constraint that rewards honesty. Spouses can waive elective-share rights in a valid marital agreement — the standard tool in blended families where both partners want their own children protected — and thoughtful planning can provide for a spouse generously through structures that also preserve an inheritance for children. What fails is silence. If your plan and your marriage haven't been looked at together, the free Colorado Estate Snapshot at /estate-snapshot will show whether they're aligned, and the free Legacy Game Plan Session with Whiteford's Colorado team can map the options from there.

The law, current

What Colorado families should know in 2026

$15M

Federal exemption — now permanent

The 2025 federal tax law made the estate and gift tax exemption permanent at $15,000,000 per person (indexed) beginning in 2026 — roughly $30M for a married couple with proper planning. Colorado imposes no state estate or inheritance tax. Plans written under older, lower exemptions often carry structures families no longer need — or miss opportunities they now have.

Colorado probate: simpler — but not simple

Colorado follows the Uniform Probate Code: many estates qualify for informal probate, and small estates under an inflation-indexed threshold can often skip court entirely via affidavit. But without a will, Colorado's intestate-succession statutes — not your wishes — decide who inherits, and blended families are where those defaults surprise people most.

Clocks

Dispute deadlines run quietly

Will contests, trust challenges, creditor claims, and fiduciary-misconduct actions in Colorado all carry deadlines — some triggered by notices a beneficiary may not even recognize as starting a clock. If something about an estate feels wrong, the single most protective step is learning your specific deadlines early.

Frequently asked questions

Can a spouse be completely disinherited in Colorado?

Not without their consent. A will can say anything, but Colorado's elective share gives a surviving spouse the right to claim a protected portion of the augmented estate regardless of the will's terms. The practical exceptions involve consent: a spouse can waive these rights in a valid prenuptial or postnuptial agreement, and a spouse who takes no action within the limited election window keeps only what the will provides. Disinheritance by stealth, though — through titling or trusts alone — is exactly what the augmented-estate rules exist to prevent.

How much is the elective share in Colorado?

It depends primarily on the length of the marriage. Colorado uses a sliding scale: the protected share starts small for brief marriages and grows substantially for long ones, reflecting the law's view of marriage as an economic partnership that deepens over time. The share is calculated against the augmented estate — a broad measure that includes many non-probate assets — not just what passes under the will. The current statutory details appear in the vetted law summary on this page, and an attorney can run the actual numbers for your situation.

Does the elective share apply to assets in a trust or with beneficiary designations?

Often, yes — this surprises people on both sides of these disputes. The augmented-estate calculation is designed to look past labels and capture a realistic picture of the couple's wealth, which can include revocable trust assets, certain joint accounts, beneficiary-designated assets, and some transfers made before death. So moving everything into a trust does not, by itself, defeat a spouse's rights. Which specific assets count is a technical, fact-heavy question — one of the main things counsel analyzes before anyone decides to elect or to resist an election.

How long does a surviving spouse have to claim the elective share?

The window is limited, and it can be short — measured against the estate proceedings, not against your grief timeline. Missing it generally means keeping whatever the will provided, however little. Because the decision requires real information — a full inventory of probate and non-probate assets — a surviving spouse who feels shortchanged should start the analysis promptly rather than waiting to see how administration goes. An attorney can protect the deadline while the underlying decision is still being carefully weighed.

Can a prenuptial agreement waive the elective share in Colorado?

Yes. A valid marital agreement can waive elective-share rights, and such waivers are standard, sensible planning in blended families where each spouse wants children from a prior marriage protected. The key word is valid: waivers can be challenged where there wasn't fair disclosure of assets, meaningful opportunity for independent counsel, or where the agreement's execution was flawed. If you're planning a marriage with significant assets on either side — or questioning a waiver you signed — have the agreement reviewed by counsel who handles both marital agreements and estates.
