The will that surfaced after your father's death does not sound like him. It was signed in his last year, when he was confused and isolated; it cuts out two of three children; and the person who arranged the signing inherits nearly everything. The legal question is whether the facts can prove what the family already senses.
A will contest is not an argument that the document is unfair — Colorado law lets people leave property in ways their families dislike. It is an argument that the document is invalid: not the free choice of a person with capacity, or never properly executed.
Whiteford's Colorado team brings and defends will contests statewide. This page covers the recognized grounds, why the window to act can be short, and what a contest looks like.
The grounds Colorado courts recognize
Every viable contest rests on one or more established grounds. Suspicion and hurt feelings are not enough; a pattern of proof matched to a legal theory is. Most Colorado contests draw on a short list.
These theories travel together: a person with diminished capacity is exactly the person most vulnerable to undue influence, and a hasty signing arranged by an interested party is where execution defects appear. Early case evaluation decides which ground the evidence supports best — and which merely feels true.
- Lack of testamentary capacity: the signer could not understand their property, their family, and what the will would do
- Undue influence: someone in a position of power substituted their wishes for the signer's own
- Improper execution: the signing failed Colorado's formalities for witnesses or acknowledgment
- Fraud or forgery: the signer was deceived about the document, or never signed it
Contest windows: why timing decides cases before merits do
Probate is built to reach finality. Once a will is admitted, the time to challenge it can be short — and formal notices can shorten it further. Colorado's deadlines here are technical and unforgiving, so we will not generalize beyond this: if you doubt a will, get specific advice about your own deadline now.
Timing also matters for evidence: medical records get archived, the drafting attorney's memory fades, witnesses scatter, and financial records become harder to assemble. The strongest contests are investigated early, while the estate is open and the proof fresh.
What a contest actually looks like — and how we approach it
A well-run contest is an evidence project. We obtain medical records bearing on capacity, the drafting attorney's file, prior wills showing the long arc of true intent, and financial records revealing who controlled what. Then we test the theory honestly: some contests should be brought, some settled, some never filed — and we tell you which.
We also defend wills: personal representatives and rightful beneficiaries deserve counsel when a disappointed heir attacks a document that reflects the signer's true wishes. Either way, the first step is a free Legacy Game Plan Session — and if you want your own plan to resist challenge, the free Colorado Estate Snapshot at /estate-snapshot shows where it is vulnerable.
