The dispute didn’t start the day your parent died. It started years earlier.
Probate court is where the dispute surfaces — but the conditions that produced it were laid down long before. A will written without family conversation. A beneficiary designation that contradicts the will. A late-life remarriage that no one talked about openly. A sibling who feels they were promised something nobody else heard. By the time the petition is filed, the family conflict has been brewing for a decade.
This post is the version of the conversation you can have now, while everyone is still alive. What probate court actually is. How the process works. Why inheritance disputes happen, what gets contested, and what doesn’t. The cost of fighting through probate. And what families can do — both before and during — to keep a difficult moment from becoming a destructive one.

What probate is.
Probate is the court-supervised process of administering a deceased person’s estate. The court:
- Authenticates the will (or determines that no valid will exists)
- Appoints an executor (named in the will) or administrator (if no will exists, or the named executor declines)
- Identifies and inventories the estate’s assets
- Notifies creditors so debts can be paid
- Resolves disputes if any arise
- Distributes the remaining assets to beneficiaries
- Closes the estate once everything is paid and distributed
In most states, probate takes between 6 and 18 months for a typical estate. Costs run roughly 3 to 7% of the estate’s value when you factor in court fees, executor compensation, and legal fees (American Bar Association — Probate Process Overview). Contested estates take much longer and cost much more.
Not every asset goes through probate. Assets that pass outside probate — life insurance with named beneficiaries, retirement accounts with named beneficiaries, joint tenancy property, assets held in a Revocable Living Trust (RLT), and Transfer-on-Death (TOD) or Payable-on-Death (POD) accounts — bypass the process entirely and pay directly to whoever is named.
This is why beneficiary designations matter so much. A 30-year-old retirement account that names a long-divorced spouse will pay that spouse, regardless of what the will says. No probate court will fix that.
How probate works, in plain language.
Step by step, from the day after death:
Step 1 — Filing the petition. Someone (usually the named executor, sometimes a family member) files a petition with the probate court in the county where the deceased lived. The will (if one exists) is filed alongside the petition.
Step 2 — Notice to interested parties. The court requires that all heirs, beneficiaries, and known creditors be formally notified. This is the moment when family members who weren’t involved in caregiving suddenly find out what’s in the will. Surprises here are a leading source of disputes.
Step 3 — Authentication of the will. The court reviews whether the will meets state requirements (proper signatures, witnesses, notarization where required). If valid, the will is admitted to probate.
Step 4 — Executor or administrator appointed. The court formally grants the executor authority (usually called “Letters Testamentary”). The executor now has legal standing to act on behalf of the estate.
Step 5 — Inventory and appraisal of assets. The executor lists everything the deceased owned, with current values. Real estate may need formal appraisal. Investment accounts get statement values as of date of death.
Step 6 — Creditor period. State law specifies a window — typically 4 to 6 months — during which creditors can file claims against the estate. The executor reviews each claim, pays valid ones, and contests invalid ones.
Step 7 — Tax filings. Final personal income tax return for the deceased. Estate income tax returns for any income earned during probate. Federal estate tax return if the estate exceeds the federal exemption (currently very high — over $13 million for an individual in 2025). State estate or inheritance tax returns where applicable.
Step 8 — Distribution. Once debts and taxes are paid and any disputes resolved, the executor distributes remaining assets according to the will (or state intestacy law if no will).
Step 9 — Closing the estate. The executor files a final accounting with the court, the court approves, and the estate is formally closed.
For a clean, uncontested estate, the entire sequence runs about 6 to 12 months. For a contested estate, multiply that by 2 to 5.
Why disputes happen.
Inheritance disputes that end up in probate court tend to fall into a handful of categories. Recognizing the patterns helps families both prevent disputes and respond to them when they arise.
1. Will contests. A family member challenges the validity of the will itself. Common grounds:
- Lack of capacity — the claim that the deceased wasn’t of sound mind when signing.
- Undue influence — someone manipulated the deceased into changing the will.
- Fraud or forgery — the will isn’t authentic.
- Improper execution — witness or notarization requirements weren’t met.
Will contests are the highest-stakes disputes. They can void the will entirely and trigger intestacy (state law deciding who gets what), or void specific provisions while keeping the rest.
2. Executor disputes. Beneficiaries challenge how the executor is administering the estate. Claims include:
- Self-dealing (executor benefiting personally from estate decisions)
- Failure to inventory or report
- Unreasonable delays
- Hidden assets
- Improper payment of debts
Family members appointed as executor face this scrutiny most often — the perceived conflict of interest is real even when behavior is clean. Professional executors (banks, trust companies) face fewer disputes but cost more.
3. Beneficiary disputes. Beneficiaries fight among themselves about specific bequests, valuations, or interpretation of will language. Sometimes about who gets which house, sometimes about who gets the family heirloom, sometimes about whether a gift to one child counts against their share of the estate.
4. Disinheritance and surprise heirs. A will explicitly leaves out someone who expected to inherit, or names someone the family didn’t know existed. Both produce contests. Surprise heirs are more common than people realize — late-life relationships, previously unknown children, second marriages.
5. Creditor claims. Creditors file claims the estate believes are invalid. This is technically not a beneficiary dispute, but it affects what’s left to distribute, which makes it one in practice.
What can be challenged. What can’t.
Three reality checks worth understanding before any family considers going to court:
You cannot contest the will simply because you disagree with it. Disinheritance is legal. If your parent had capacity and wasn’t unduly influenced, they’re allowed to leave their estate however they want — including in ways the family considers unfair. Disagreement is not grounds for a contest. Evidence of incapacity, undue influence, fraud, or improper execution is.
You cannot contest beneficiary designations through probate. Life insurance, retirement accounts, and TOD/POD accounts pay directly to the named beneficiary outside probate. The probate court has no jurisdiction over those assets. Challenges to beneficiary designations require separate legal action — usually challenging the change itself for capacity or undue influence at the time the change was made.
You cannot challenge a Revocable Living Trust through probate. Trusts are administered outside probate court entirely. Challenging trust terms or trustee actions requires separate trust litigation.
Many disputes that feel valid in family meetings have no legal grounds. A parent’s promise that wasn’t put in writing usually has no enforceability. “Mom always said this house would be mine” doesn’t override what the deed and will say.
What contested probate actually costs.
Will contests and other contested probate proceedings can run $10,000 to $250,000 or more in legal fees, depending on complexity, length, and how many parties are involved. The estate often pays both sides’ fees — meaning the legal fight directly drains what would have been the inheritance.
Beyond financial cost, contested probate consumes time (multi-year proceedings are common) and relationships. The family that walked into the courtroom usually doesn’t walk out the same way.
This is why most experienced probate attorneys steer clients toward mediation and Alternative Dispute Resolution (ADR) before formal litigation. Mediation typically costs a fraction of contested litigation, completes in weeks rather than years, and preserves family relationships in ways litigation can’t.
How to prevent disputes before they start.
Most inheritance disputes are preventable. The patterns that prevent them, in order of leverage:
1. Have the conversation while everyone is alive. Most disputes are surprises in disguise. A parent who’s transparent about their estate plan with adult children — even in broad terms — produces fewer disputes than a parent who keeps it private. “This is what’s in the will. This is why.” See How to Start Beneficiary Conversations with Parents for the conversation framework.
2. Update beneficiary designations. A will that conflicts with beneficiary designations on accounts is the most common source of post-death disputes. Walk through every account with your parent. Make sure designations match current intent. The will doesn’t override the beneficiary designation, no matter what the will says.
3. Use a Revocable Living Trust if appropriate. Trusts pass outside probate, are private (probate is public record), and reduce dispute opportunity. Not every family needs one — talk to an elder law attorney about whether the cost and complexity make sense for your parent’s situation. See Roles of Elder Law Attorneys in Caregiving.
4. Address late-life relationships explicitly. Second marriages, common-law partners, and late-life relationships are a leading source of inheritance disputes. A clear, current will that explicitly addresses the new partner and the adult children from prior relationships prevents most of these. Vague wills produce maximum conflict.
5. Pick the right executor. The right executor is responsive, organized, even-handed, and respected by all heirs. The “right” executor isn’t always the oldest child or the most successful one. A family member who works well with the others is worth more than a family member with the right credentials. Professional executors (banks, attorneys) cost more but bring neutrality.
6. Keep estate documents current. A 25-year-old will that names an executor who has since passed away, or beneficiaries who are now divorced spouses or estranged children, is worse than no will. Review every five years and after every major life event.
What to do if you’re in a probate dispute.
If you’re already in the middle of an inheritance dispute or anticipating one:
Get a probate attorney immediately. This is not the time to handle it yourself. Probate litigation is procedural and the deadlines are unforgiving.
Document everything. Communications with the deceased, witnesses to capacity or relationships, any evidence of undue influence, prior wills or amendments. Memory fades; written records survive.
Consider mediation before litigation. Ask your attorney about mediation or ADR. Most cases resolve faster, cheaper, and more cleanly through mediation than through trial.
Be realistic about strength of position. Will contests succeed less often than people expect. Disagreement isn’t grounds. Evidence is.
Consider the long arc. A pyrrhic legal victory that estranges siblings for the next thirty years isn’t a win. Family relationships often outlast any single inheritance.
“The dispute didn’t start the day your parent died. It started years earlier — in a will written without family conversation, a beneficiary designation that contradicts it, a late-life remarriage no one talked about openly.”
FROM TWO ENDS OF THE PROBATE SPECTRUM:
Across the parents and stepparents I’ve cared for, I’ve watched estate transitions go in two very different directions.
The version that worked: my stepmother’s estate, then my dad’s, ran cleanly. The planning had been done years earlier — current wills, updated beneficiary designations, a clear executor, a family that knew in broad terms what to expect. There was no surprise. There was no contest. The financial part of the transition was the easy part of the loss.
The version that didn’t was with my Mom’s second husband. When he passed during a nap one afternoon, she discovered that his life insurance — which everyone assumed would pass through his current marriage — still named his ex-wife as beneficiary. The designation hadn’t been updated in fifteen years. Hundreds of thousands of dollars went to the ex-wife. She had no recourse — beneficiary designations override wills, override marriages, override everything except a separate legal challenge to the designation itself, which would have required proving capacity issues or fraud at the time the designation was set.
Mom’s response, fifteen years later, was characteristic: “Too bad.” She moved forward. But the lesson sat with me — a fifteen-year-old beneficiary form, never updated, can rewrite a family’s financial future in a way no probate court can fix.
The pattern across both stories: the time to prevent inheritance disputes is now, while everyone is alive. Probate court is where they get expensive, public, and slow. The kitchen table is where they get prevented.
Honor is in the name of our company for a reason: ElderHonor. Honoring our parents includes the unglamorous work of making sure their wishes can actually be honored when the moment arrives — through documents that match each other, beneficiary designations that match the will, and conversations that prevent the surprises that drive most disputes. The post-death moment isn’t the time to fix things. It’s the moment when the work you did beforehand either holds or doesn’t.
Where to start today.
If you’re trying to prevent a future dispute:
- Have the conversation with your parent. Even in broad terms. Use How to Start Beneficiary Conversations with Parents.
- Walk through every account to verify beneficiary designations match current intent.
- Read the will together if your parent is willing — or at minimum, confirm where it’s kept and who the executor is.
- Schedule an elder law attorney review if estate documents are more than 10 years old or if the family situation has changed (remarriage, new children, estrangement).
If you’re already in a dispute:
- Get a probate attorney — your state bar’s lawyer referral service or the National Academy of Elder Law Attorneys (NAELA).
- Don’t act unilaterally in the meantime. Don’t move funds, don’t sell assets, don’t disburse anything without consulting counsel.
- Ask early about mediation. Most attorneys can reach out to opposing counsel; many disputes resolve in mediation.
- Keep family communication civil to whatever extent possible. The dispute will end. The family doesn’t have to.
You’ve got this.

Some additional notes:
The probate timeline (6–18 months) and cost (3–7% of estate value) are national averages. State-specific timelines and costs vary significantly. California probate, for example, is notoriously slow and expensive; many smaller states are faster and cheaper. Look at your State for specifics.
The federal estate tax exemption (over $13 million for an individual in 2025) is set by federal law and adjusts periodically. The 2017 Tax Cuts and Jobs Act provisions affecting this exemption are currently scheduled to sunset at the end of 2025. Verify the current exemption amount before making any decisions.
The “$10,000 to $250,000+” cost range for contested probate is illustrative; individual cases vary widely.
Will contest grounds (capacity, undue influence, fraud, improper execution) are the standard four, but state law varies on burden of proof, who has standing to contest, and time limits for filing contests.
The “estate often pays both sides’ fees” framing is generally true but state-specific. Some states limit fee-shifting; verify for your State.
Mediation and ADR availability varies by state; some probate courts mandate mediation before trial, others don’t.
Small-estate procedures (simplified probate for estates under a state-specific threshold) exist in most states but with widely varying limits. Verify with the State the estate is located.
