Most people create an estate plan to avoid conflict. They want their family to grieve in peace, not argue in court.
But at Reuter Corbett, we see the opposite outcome more often than you’d think. A poorly constructed or outdated estate plan doesn’t prevent disputes. Often times, it creates them.
We’re probate and trust litigators, not estate planners. We don’t draft wills or set up living trusts.
We step in when something has already gone wrong.
A beneficiary has been cut out without explanation. A trustee is hiding assets. Siblings are at war over what Mom or Dad “really meant.” Over the years, we’ve noticed a handful of estate planning mistakes that show up again and again in contested cases across Oregon, Washington, and Idaho.
If you’re reviewing a loved one’s estate plan and spot any of the following red flags, it may be time to speak with a probate litigation attorney before those warning signs turn into full-blown litigation.
1. Vague, Contradictory, or Ambiguous Language
An estate plan needs to be precise.
When a will or trust uses broad, open-ended language, beneficiaries can often interpret the document in radically different ways.
Phrases like “my children shall share equally” might sound fair, but they create immediate problems if the decedent also left specific bequests to some children and not others. Does the specific gift come out of that child’s equal share, or is it extra?
Ambiguous descriptions of property are another common flashpoint. “My jewelry collection to my daughter” seems straightforward until you realize the collection was sold, expanded, or divided over the years.
Contradictions between documents are equally dangerous. We’ve seen cases where a will seems to prescribe one distribution scheme, but a trust seems to contain conflicting instructions. Estate planning documents that don’t align can lead to confusion and ultimately, disputes about their meaning. Beneficiaries hire, attorneys, and the estate bleeds money in litigation until a court can sort out the conflicting interests.
Watch for language that leaves room for interpretation, conflicting provisions between the will and trust, or assets described in ways that no longer match reality.
2. Late-Life Changes That Favor One Person Unexpectedly
This is the hallmark of undue influence, and it’s one of the most common grounds for contesting a will in Oregon and Washington.
A long-standing estate plan that suddenly changes in the final months of a person’s life deserves scrutiny, especially if the changes:
- Favor a caregiver, new romantic partner, or estranged relative
- Disinherit someone who was previously included without explanation
- Were prepared by an attorney the beneficiary arranged or paid for
- Occurred while the decedent was isolated from family or experiencing cognitive decline
Oregon courts look at whether a confidential relationship existed, whether suspicious circumstances surrounded the change, and whether the beneficiary had opportunity and motive to exert pressure. No single factor proves undue influence, but when several appear together, courts treat it seriously. In In re Estate of Reddaway, 214 Or. 410 (1958), the Oregon Supreme Court made clear that circumstantial evidence, taken as a whole, can invalidate a will that no longer reflects the testator’s true wishes.
If you see prior wills or trusts that distributed assets very differently, or sudden disinheritance without explanation, or a pattern of isolation and control by the newly favored beneficiary, contact Reuter Corbett and we can help you evaluate whether further investigation is warranted.
3. Improper Execution or Reliance on DIY Documents
Oregon, Washington, and Idaho all have specific statutory requirements for how a will must be signed and witnessed. When those rules aren’t followed, the entire document can be challenged on formal grounds.
Online templates and do-it-yourself estate planning kits are particularly risky. They rarely account for state-specific execution requirements, and they often produce documents that look legitimate but fail under legal scrutiny. Common problems include missing witnesses, witnesses who are also beneficiaries, improper notarization (a notary cannot substitute for witnesses in most will executions), lack of a self-proving affidavit, which forces additional court proceedings, or documents executed without the testator having sufficient mental capacity.
We’ve handled cases where a decedent used an online form that appeared valid on its face but was missing critical language required by state law. The result was a will contest that could have been avoided entirely with proper drafting and execution.
Documents that appear to be templates, are missing witness signatures, notarization in place of witness attestation, or any sense that the decedent executed paperwork without legal guidance, all warrant a second look from someone who knows what the state law actually requires.
4. Overly Aggressive No-Contest Clauses
No-contest clauses, also called in terrorem clauses, are designed to discourage beneficiaries from challenging a will or trust. They typically state that anyone who contests the document forfeits their inheritance. On paper, this sounds like a deterrent. In practice, it often backfires.
When a no-contest clause is too broad or paired with an unfair distribution, it can actually provoke litigation rather than prevent it. A beneficiary who believes they’ve been wronged may decide they have nothing to lose by challenging the document, especially if their share was small to begin with. Oregon courts have tools to evaluate these clauses, and under certain circumstances, a beneficiary can challenge a will on probable cause without triggering forfeiture.
More importantly, no-contest clauses don’t deter claims based on undue influence, lack of capacity, or fraud. Those are foundational validity challenges, not mere disagreements over distribution. A beneficiary attacking the document’s validity may not be “contesting” the will in the way the clause intends, they’re arguing the document isn’t a valid will at all.
Be wary of a no-contest clause that seems designed to silence legitimate concerns, especially when paired with unexpected disinheritance or a drastic reduction in a beneficiary’s share.
5. Outdated Beneficiary Designations and Unfunded Trusts
This one gets overlooked constantly.
One of the most destructive estate plan mistakes involves assets that pass outside the will entirely.
Life insurance policies, retirement accounts, and payable-on-death bank accounts are governed by beneficiary designations, not by the terms of a will. When those designations are outdated, the estate plan falls apart regardless of how well the will was written.
We’ve litigated cases where an ex-spouse was still named on a life insurance policy years after divorce. We’ve seen decedents whose trust was never actually funded, meaning assets remained in the decedent’s individual name and passed through probate under intestacy rules. In other cases, the decedent acquired new property after creating the plan and never retitled it into the trust, creating a partial intestacy that triggered litigation among heirs.
These situations are especially frustrating because the decedent likely intended a different outcome. But intent doesn’t control if the documents and titling don’t match. The law looks to what was actually signed or executed, not what someone may have intended but never got around to actually doing.
Check whether beneficiary forms predate major life events like divorce, remarriage, or the birth of children. Look for assets held individually that should have been transferred to a trust, or retirement accounts with no named beneficiary at all.
When to Consult a Probate Litigation Attorney
Not every red flag means you should run to court. Some estate plan mistakes can be resolved through negotiation or clarified with additional documentation.
But if you’re seeing multiple warning signs, especially sudden changes, suspicious circumstances, or significant financial harm, it’s worth getting a legal opinion before deadlines expire.
In Oregon and Washington, you generally have four months from the date probate notice is published or delivered to file a will contest under ORS 113.075 and RCW 11.24.010 respectively. Idaho has no specific time limit for contesting a will, however, once probate of a will is initiated, the will must be contested prior to close of the probate proceeding.
Quietly gathering records now, while preserving evidence, is often the best first step. Don’t confront the influencer right away. Accusing a relative or caregiver too quickly can lead them to destroy documentation that you’ll need later.
