Connecticut Will Contests

A Connecticut will contest is an appeal from probate to the Superior Court under Conn. Gen. Stat. § 45a-186, due 30 days after the court sent the decree.

By Settled Editorial

A Connecticut will contest runs as an appeal from probate to the Superior Court under Conn. Gen. Stat. § 45a-186. Any person aggrieved by an order, denial or decree of a Probate Court may appeal, and the complaint is due on or before the thirtieth day after the date the Probate Court sent that decree. The clock runs from the sending, not from the day you read the envelope.

That single sentence puts Connecticut outside most of what you will read about contesting a will. Connecticut has no informal probate track and no separate contest petition filed in the Probate Court. Section 45a-286 makes the Probate Court hold a hearing before it proves or disapproves any will, so an objection is raised at that hearing first, and the appeal follows the decree. This guide walks the hearing, the aggrieved-person test, the grounds, the 30-day complaint, the two windows that run longer, and what a Connecticut contest costs the people who inherit. Read it with the Connecticut will requirements guide for what the document had to do in the first place, and the Connecticut probate guide for how an estate moves through the court.

The Hearing Comes Before the Appeal

Section 45a-286 is short and it decides the shape of every Connecticut will dispute. A Probate Court shall, before proving or disapproving any last will and testament or codicil, hold a hearing on it, with notice given to all parties known to be interested in the estate. The court may skip that notice in two situations only: every interested party signs and files a written waiver, or the court dispenses with notice for cause shown. The statute names one sufficient cause, which is a finding that the estate is not more than enough to pay administration, funeral and last sickness expenses.

Two practical points fall out of that.

First, the hearing is the least expensive stage. Capacity, execution, undue influence and revocation are raised there, in front of the probate judge, with the attesting witnesses available, before anyone pays a Superior Court entry fee. Section 45a-285 lets the attesting witnesses prove the will by sworn affidavit written on the will or on a paper attached to it, and the Probate Court accepts that affidavit as if the testimony had been taken in court. The annotation printed under the section adds the counterweight a contestant needs: a party contesting the will may require the attendance of all witnesses within reach of process.

Second, the waiver of notice matters. A written waiver satisfies the notice requirement, which closes the twelve-month window that § 45a-187 otherwise holds open for someone who was never notified. A waiver is a short document that closes a long window, and what it gives up is worth understanding before it is signed.

Connecticut also puts a clock on the judge. Section 45a-134 requires a probate judge who has commenced a hearing in a contested case to render a decision not later than 120 days from the date the hearing was completed. If the decision is late, any party may petition the Probate Court Administrator for relief, which can include reassigning the case to another judge.

Who Can Appeal: The Aggrieved Person Test

Section 45a-186(b) opens the door to "any person aggrieved" and to nobody else. The annotations printed under that section in the General Statutes define the term tightly. An aggrieved person shows a direct pecuniary interest in the matter in controversy that the decree will injuriously affect. Certainty, not possibility, is the standard.

The reported outcomes draw a clean line:

  • A beneficiary under an earlier will is aggrieved by a decree admitting a later one.
  • A trustee under a will whose beneficiaries are hurt by a later will is aggrieved.
  • A bidder on estate property has enough interest in the sale approval to appeal.
  • A judgment creditor of an heir who was disinherited has no standing.
  • Members of a fluctuating group of beneficiaries of a public charity lack the direct pecuniary interest the statute wants.

The working question is financial: whether the person appealing would receive more if the decree were undone. Heirs who would take under the Connecticut intestate succession rules generally can. So can a legatee cut back by a newer will. A friend who appears in no version of the document generally cannot. An appeal filed by someone who is not actually aggrieved is void for want of jurisdiction, which makes aggrievement the threshold question in every case.

The Grounds for Contesting a Connecticut Will

Connecticut never gathers the grounds into a single statute. They come out of chapter 802a and the case annotations printed under those sections.

Defective Execution

Section 45a-251 states the rule as a prohibition. A will or codicil shall not be valid to pass any property unless it is in writing, subscribed by the testator, and attested by two witnesses, each of them subscribing in the testator's presence. Connecticut writes in no forgiveness clause, so a document that misses a formality cannot be rescued by proof that the decedent meant every word.

One escape hatch sits inside the same sentence. A will executed according to the laws of the state or country where it was executed may be admitted to probate here and passes Connecticut property. For a decedent who signed in another state, that is a live answer rather than a technicality, and it is the only route a handwritten will reaches a Connecticut estate.

The annotation printed under § 45a-251 carries the point that decides many of these cases: even when the contestant affirmatively pleads lack of due execution, the burden of proving due execution stays on the proponent of the will.

Lack of Testamentary Capacity

Section 45a-250 allows any person eighteen years of age or older, and of sound mind, to dispose of an estate by will. The annotations under it fix the test and the timing. Capacity is determined as of the time the will is made, and the standard does not demand that the testator know the full and specific condition of the property. It asks for sufficient mind and memory to know and understand the business being transacted at signing. A person whose condition rises and falls can sign a valid will during a clear stretch, which is why these cases turn on medical records and witness accounts from the days around the signing date. The annotations also record that statements the testator made after execution are admissible on capacity and on undue influence.

Undue Influence

Undue influence means the will expresses somebody else's wishes. Connecticut assigns the burden to the party raising it, with one shift worth knowing. The annotation under § 45a-250 states that the burden rests on the one alleging undue influence, except where a stranger who holds a relationship of trust and confidence toward the testator is a principal beneficiary and the natural objects of the testator's bounty are excluded. That exception does not apply when the principal beneficiary is the testator's own child.

The pattern that draws the closest look is familiar: a caregiver or late-arriving companion isolates the testator, selects the drafting attorney, attends the signing, and takes most of the estate.

Revocation

Section 45a-257 is exclusive. A will or codicil shall not be revoked in any manner except by burning, cancelling, tearing or obliterating it by the testator, or by another person in the testator's presence at the testator's direction, or by a later will or codicil. Sections 45a-257a through 45a-257d handle the family changes that alter a will by operation of law, including a marriage that follows execution, children born or adopted afterward, and a marriage later terminated.

Revocation has its own remedy. Section 45a-295 lets a Probate Court that learns mid-settlement that the governing will was revoked revoke, annul and set aside its own decree proving that will, then continue under a later will or as an intestate estate.

A Gift to a Subscribing Witness

Section 45a-258 voids any devise or bequest to a subscribing witness, or to that witness's husband or wife, unless the will is legally attested without that signature or the devisee is an heir of the testator. This attacks one gift rather than the whole will, and it is the cheapest objection on this page to verify. Compare the signature block against the beneficiary list.

The 30-Day Clock and the Two Windows That Run Longer

Section 45a-186(b) sets the deadline. Except as §§ 45a-187 and 45a-188 provide, an appeal from an order, denial or decree must be filed on or before the thirtieth day after the date the Probate Court sent it. The period is calculated from the date the court sent the decree by mail or transmitted it by electronic service, whichever is later. A 45-day window exists, and it is reserved for conservatorship, guardianship and termination matters that the statute enumerates by section number. A will decree is not among them.

Two sections open longer windows.

SituationWindowStatute
Adult who was present, had legal notice, was told of the right to request a hearing, or waived it30 days from the sending§ 45a-186(b)
Adult who had no notice to be present and was not present, or was never given notice of the right to request a hearing12 months§ 45a-187(a)
Person who was a minor when the decree entered, with no qualifying guardian notice12 months after reaching majority§ 45a-188(a)
Minor whose guardian or guardian ad litem had legal notice of the hearingSame period as § 45a-186§ 45a-188(b)

Section 45a-186c(b) adds the one action that stops the clock. An appellant who cannot pay the costs files an application for waiver of those costs with the clerk of the Superior Court within the time permitted for filing the appeal, and that filing tolls the appeal deadline until judgment on the application. The annotation under the same section marks the trap on the other side: a motion for revocation under § 45a-128 does not toll the appeal period. Filing a request with the Probate Court while the 30 days run does not buy time.

How the Appeal Gets Filed

Section 45a-186(c) through (g) sets out the mechanics, and each step carries its own deadline.

  1. A complaint is filed in the Superior Court. The judicial district is the one where that Probate Court sits. Where a probate district falls in more than one judicial district, the statute accepts any superior court located in a judicial district that holds any part of the probate district. The complaint states the reasons for the appeal and attaches a copy of the decree.
  2. Every interested party is served. Service goes by state marshal, constable or an indifferent person, in hand or by leaving a copy at the party's residence or at the address on file with the Probate Court. Failure to serve does not strip the Superior Court of jurisdiction, and the court will order further notice on motion.
  3. A copy goes to the Probate Court by mail. The court that issued the decree and the judge who signed it are not parties, and the statute forbids naming them as parties in the complaint.
  4. Proof of service is filed within 15 days. The filing names the person who made service, carries that person's signature and address, and states the date and manner of service on each interested party and of the mailing to the Probate Court.

No probate form covers this. The Connecticut Probate Courts publish 197 forms across nine series and none of them is an appeal from probate, because the pleading is a Superior Court complaint. The Connecticut court directory lists each probate district and its mailing address.

Trial De Novo, With One Exception

Connecticut gives a will appellant something most states do not. The Superior Court hears the matter fresh. The annotations under § 45a-186 state the rule plainly: on an appeal from probate the trial is de novo, and the case is not presented on a transcript of the Probate Court proceeding. The Superior Court sits as a Court of Probate and exercises no greater power than that court had, and it may not consider evidence of matters that did not exist at the date of the Probate Court hearing.

Section 45a-186(d) carves out the exception. Appeals decided after a recording made under §§ 17a-498, 17a-543, 17a-543a, 17a-685 or 19a-131b, under §§ 45a-644 to 45a-667v, or under §§ 51-72 or 51-73 are on the record and are not a trial de novo. No decedents' estate section appears on that list, so a will decree lands there only through the last pair, and the parties put it there themselves. Section 51-72 lets the parties or their attorneys agree in writing to have the probate judge call in a stenographer, and § 51-73 then makes any appeal from a decision rendered on that record an appeal on the record rather than a new trial.

The consequence is worth weighing before that agreement is signed. Section 45a-186b tells the Superior Court, in a case heard on the record, not to substitute its judgment for the Probate Court's on the weight of the evidence, and to affirm unless the findings are unconstitutional, beyond the court's authority, made on unlawful procedure, affected by other error of law, clearly erroneous on the whole record, or arbitrary and capricious. Section 45a-186a charges the transcript cost to the appellant, with payment from the Probate Court Administration Fund only on an affidavit of inability to pay. Agreeing to a stenographer trades a second full hearing for a deferential review, and the appellant pays for the transcript.

The Special Assignment Judge, and Your 20 Days

Section 45a-186(l) lets the Superior Court refer a probate appeal to a special assignment probate judge appointed under § 45a-79b and assigned by the Probate Court Administrator. Subsection (l)(3) lists the matters that may never be referred: commitment cases, children's matters, conservatorship and intellectual disability cases, appeals under § 45a-98e, and any matter a Probate Court heard on the record under §§ 51-72 and 51-73. An ordinary will appeal sits outside that list, so it can be sent back to a probate judge for decision.

One sentence sets up the choice. The appeal shall be heard by the Superior Court if any party files a written demand for that hearing with the Superior Court not later than twenty days after service of the appeal. That twenty-day period runs from the date the appeal is served, and nothing extends it.

The Decree Is Not On Hold

Section 45a-186(j) says the filing of an appeal does not, of itself, stay enforcement of the order, denial or decree. The executor keeps the letters. Administration continues. A motion for a stay may be made to the Probate Court or to the Superior Court, and filing one in the Probate Court does not stop the Superior Court from acting.

That matters because a distribution can outrun the appeal. Connecticut executor duties covers what the fiduciary owes the estate while an appeal is pending, and a stay is worth less once the money has already moved.

What a Connecticut Will Contest Costs

Court fees are the small line. Section 52-259(a) sets the Superior Court entry fee for a civil cause at $360, and § 45a-186c(b) supplies the waiver application for an appellant who cannot pay. Fee amounts change, and the Superior Court clerk's office is where the current figure is confirmed.

Two provisions shift real money.

Costs can follow the loser. Section 45a-186c(a) allows costs to be taxed in favor of the prevailing party in the same manner and to the same extent as costs are allowed in Superior Court judgments.

The estate pays to defend the will, and the beneficiaries fund it. Section 45a-294 requires the Probate Court to allow the executor just and reasonable expenses in defending the will, whether or not the will is admitted to probate. Subsection (b) extends that allowance to the appeal, for supporting and maintaining the will or defending against it. Subsection (c) then charges those expenses pro rata against the respective rights or shares of the devisees and legatees under the will and the distributees of the estate. A losing contest shrinks the pot for everyone, including the contestant's own share of whatever remains.

Attorneys, depositions, medical records and handwriting experts are where the number grows. Four questions generally decide whether an appeal is worth its cost: whether the person appealing is aggrieved in the pecuniary sense, whether there is evidence of a recognized ground rather than disappointment, whether the thirty days have run, and whether a negotiated settlement would reach the same place sooner and for less. A licensed Connecticut probate litigator is the person who answers those against the facts of a particular estate.

When the 30 Days Have Already Passed

Section 45a-24 closes the door hard. All orders, judgments and decrees of courts of probate rendered after notice and from which no appeal is taken shall be conclusive, entitled to full faith, credit and validity, and not subject to collateral attack, except for fraud. Two narrower paths stay open.

Reconsideration in the Probate Court. Section 45a-128(b) lets the court reconsider, modify or revoke an order or decree on its own motion or on the written application of an interested person, filed within 120 days after the date of the order and before any appeal is filed or after all appeals are withdrawn. The grounds are narrow: consent of all parties in interest, failure to give legal notice to a party entitled to it, a scrivener's or clerical error, or the discovery of parties in interest unknown to the court. Decrees authorizing the sale of real estate are excluded. Subsection (e) protects assets already lawfully transferred or distributed before notice of the reconsideration hearing issued. Subsection (c) restarts a full appeal period on any modification or revocation. Remember the tolling annotation above: this application does not extend the 30 days.

An equitable action alleging fraud. The annotations printed under § 45a-24 record that an action in equity to set aside a decree admitting a will to probate is a direct attack that falls outside the section's bar, and that a plaintiff seeking Superior Court jurisdiction must bring a separate action collaterally attacking the decree and invoke the court's equitable jurisdiction by alleging fraud or other equitable grounds. That is specialist litigation, and it belongs with a Connecticut probate litigator rather than with a form.

No-Contest Clauses in Connecticut

The Connecticut General Statutes contain no section on no-contest clauses. Chapter 802a, which governs the execution and construction of wills, runs from § 45a-250 to § 45a-267 and never addresses a forfeiture provision. Neither does the decedents' estates chapter. The answer lives in Connecticut case law rather than in text you can read at the anchor.

One boundary is visible in the code itself. The annotations printed under § 45a-186 report a holding that a will provision declaring an order of the Probate Court conclusive and allowing no appeal is invalid. A testator cannot write the statutory right of appeal out of existence. The same annotation list records that the effect of a clause forfeiting a beneficiary's gift for attacking the will has been litigated here, without stating the outcome on the page. Where a will carries a forfeiture clause, a licensed Connecticut probate litigator is the person who reads it against the current case law, since the gift at risk is usually larger than the filing fee.

Two Remedies That Are Not a Will Contest

The surviving spouse's statutory share. Section 45a-436 lets a surviving spouse elect a life estate of one third in value of all the property passing under the will, real and personal, after debts and charges are paid. The right cannot be defeated by any disposition of property by will to other parties. The election runs on its own clock: written notice filed with the Probate Court not later than 150 days after the mailing of the decree admitting the will to probate, or the share is barred. A spouse who elects proves no misconduct and contests nothing. Section 45a-436(g) is the one bar, and it removes both the statutory share and the intestate share from a spouse who abandoned the decedent without sufficient cause and continued the abandonment to the death. The Connecticut surviving spouse rights guide covers the election and the allowances.

A revocable trust challenge. When the estate plan runs through a funded revocable trust, the deadline is not § 45a-186. Section 45a-499qq gives a person the earlier of one year after the settlor's death, or 120 days after the trustee sent that person a copy of the trust instrument together with notice of the trust's existence, the trustee's name and address, and the time allowed for commencing a proceeding. The trustee shortens the window by sending that packet, so the date the packet arrived is the date that fixes the deadline.

What Happens If the Appeal Succeeds

The estate does not disappear. It passes under whatever instrument or rule stands next in line. Where an earlier valid will exists, the estate follows that document. Where none exists, the estate passes under the Connecticut intestate rules in § 45a-437 and the court grants administration. A court can also strike a single tainted gift and leave the rest of the will intact, and § 45a-258 reaches exactly that result for a gift to a subscribing witness.

Whatever the outcome, the case ends where it started, in the probate district where the decedent was domiciled at death. Section 45a-283 fixes that venue by requiring the named executor to apply for probate within thirty days of the death to the Probate Court of the district where the testator was domiciled at death. The Connecticut probate timeline shows where the appeal window sits next to the inventory, claim and accounting dates.

Common Questions

How long do I have to contest a will in Connecticut?

Thirty days. Conn. Gen. Stat. § 45a-186(b) requires an appeal from a Probate Court order, denial or decree to be filed on or before the thirtieth day after the date the Probate Court sent it, measured from the mailing date or the electronic service date, whichever is later. Two statutes stretch that window. Section 45a-187(a) gives twelve months to an adult who had no notice to be present and was not present, or who was never given notice of the right to request a hearing. Section 45a-188(a) gives a person who was a minor when the decree entered twelve months after reaching the age of majority.

What are the grounds to contest a will in Connecticut?

Connecticut does not print a list of grounds in one section. The grounds come out of the wills chapter and the case annotations printed under it: lack of testamentary capacity under Conn. Gen. Stat. § 45a-250, defective execution under § 45a-251, revocation under § 45a-257, a void gift to a subscribing witness under § 45a-258, and undue influence, fraud, duress and forgery from Connecticut case law. The annotation under § 45a-251 records that the burden of proving due execution stays on the proponent even when the contestant pleads the defect.

Where do you file a Connecticut will contest?

In the Superior Court, not the Probate Court. Conn. Gen. Stat. § 45a-186(c) has the appellant file a complaint in the Superior Court for the judicial district where that Probate Court sits, with a copy of the decree attached and the reasons for the appeal stated. If the probate district spans more than one judicial district, any superior court in a judicial district holding part of that probate district works. Section 45a-186(f) then requires a copy mailed to the Probate Court, and it bars naming the court or the judge as a party.

Do no-contest clauses work in Connecticut?

The Connecticut General Statutes carry no section on no-contest clauses. Chapter 802a, the wills chapter, runs from § 45a-250 to § 45a-267 and says nothing about a forfeiture provision, so the answer sits in case law rather than in a statute anyone can read at the anchor. One boundary is on the record: the annotations printed under § 45a-186 report that a will provision declaring a Probate Court order conclusive and allowing no appeal was held invalid. A licensed Connecticut probate litigator is the person who reads a forfeiture clause against the current case law.

Who can contest a will in Connecticut?

Any person aggrieved by the decree, under Conn. Gen. Stat. § 45a-186(b). The annotations printed under that section define the term narrowly: an aggrieved person shows a direct pecuniary interest in the matter that the decree injuriously affects. A beneficiary under an earlier will qualifies. A judgment creditor of a disinherited heir does not. Mere unhappiness with the result is not aggrievement, and an appeal by someone who is not actually aggrieved is void.

This page is general information about appealing a Connecticut probate decree, and it does not describe any particular estate. Appeals from probate are litigation, the aggrievement test is strict, the 30-day window is short, and the executor's defense costs come out of the shares of the people who inherit. Confirm the date your Probate Court sent the decree with the Probate Court for your district, and take standing, grounds and dates in a specific matter to a licensed Connecticut attorney.
