Contest a Will in Connecticut: At a Glance
Here are the Connecticut facts that decide whether you can contest a will in Connecticut:
| Deadline to contest | There is no separate “will contest” lawsuit deadline in Connecticut — a contest happens in two stages. Stage 1: a written objection to admission of the will must be filed with the Probate Court before/at the hearing on the petition for probate of the will (Conn. Gen. Stat. § 45a-286; Conn. Probate Court Rules of Procedure § 8.5). Stage 2: once the Probate Court enters a decree admitting (or refusing) the will, an appeal to the Superior Court must be filed not later than 30 days after the date the Probate Court sent the order, denial or decree (Conn. Gen. Stat. § 45a-186(a)–(b); see also § 45a-187). The 45-day period in § 45a-186(b) applies only to conservatorship/guardianship matters under §§ 45a-644 to 45a-677, 45a-690 to 45a-703, and 45a-705a — not to will contests. After the 30 days run with no appeal, the decree is conclusive and not subject to collateral attack except for fraud (Conn. Gen. Stat. § 45a-24). |
| What starts the clock | The 30-day clock starts on the date the Probate Court SENT the order, denial or decree — measured from the date the court mailed it or the date it transmitted it by electronic service, whichever is LATER (Conn. Gen. Stat. § 45a-186(b)). It does not run from the date of death, the date of the funeral, or the date the appellant actually received the decree. The earlier objection deadline is triggered by the court’s notice of hearing on the application for administration or probate of will (form PC-200). |
| Who can contest | “Any person aggrieved by any order, denial or decree of a Probate Court” may appeal (Conn. Gen. Stat. § 45a-186(a)). Connecticut courts define aggrievement as a specific, personal and legal interest in the subject matter of the decree that has been specially and injuriously affected — a general interest common to all members of the community is not enough. In practice this means intestate heirs who would take more without the will, beneficiaries named in the will, beneficiaries under a prior or later will or codicil, a surviving spouse asserting statutory rights, and fiduciaries acting for those parties. Aggrievement must be pleaded and proved; it is jurisdictional. Ordinary estate creditors generally are not aggrieved by admission of a will because their claims are paid regardless of who inherits. |
| No-contest clause | YES, with a good-faith/probable-cause exception. Connecticut recognizes the validity of a forfeiture (in terrorem) clause in a will, but will not enforce it where the contest was begun in good faith and with probable cause and reasonable justification — South Norwalk Trust Co. v. St. John, 92 Conn. 168, 177 (1917). Connecticut has no statute codifying this; it remains common law. Connecticut courts have continued to apply the rule in the trust context, including for good-faith challenges to fiduciary conduct (see Salce v. Cardello, 348 Conn. 90 (2023)). Because “probable cause” is decided after the fact by a court, a beneficiary considering a contest may want to have counsel evaluate the risk first. |
| What the filing is called | Stage 1 is an “Objection to Admission of Will” (a written objection/appearance filed in the Probate Court district where the estate is pending, in response to the PC-200 Petition/Administration or Probate of Will; a contested matter then proceeds under a Probate Court scheduling order to a hearing on the record). Stage 2 is an “Appeal from Probate,” commenced by a complaint/appeal filed in the Superior Court in the judicial district where the Probate Court is located, with a copy filed in the Probate Court and process served on the parties (Conn. Gen. Stat. § 45a-186(a), (c)–(d)). |
| Court | The Connecticut Probate Court for the district in which the decedent was domiciled at death hears the initial contest over admission of the will. The Connecticut Superior Court (judicial district serving that probate district) hears the appeal. Connecticut has no separate “surrogate’s court”; its trial-level probate system is the Probate Court, organized into regional probate districts. |
| Jury trial | NO for a will contest. A probate appeal is not a civil “action” that carries a jury-trial right, and an appeal from a Probate Court matter heard on the record is expressly heard by the Superior Court without a jury and on the record (Conn. Gen. Stat. § 45a-186a; § 45a-186(f)–(h)). The narrow affidavit-of-intent-to-claim-a-jury-trial procedure in Conn. Gen. Stat. § 45a-98a applies only to certain title, rights and instrument-construction matters under § 45a-98(a)(3)–(6) — it does not apply to admission of a will, so contested will cases are tried to the judge. |
| Typical cost | UNVERIFIED — Connecticut does not publish official cost data for contested will cases. Connecticut Probate Court statutory filing/entry fees are set by Conn. Gen. Stat. § 45a-106a and § 45a-107 (fees for settling a decedent’s estate are calculated on the basis of the gross estate), and the Superior Court civil entry fee for a probate appeal is set by Conn. Gen. Stat. § 52-259. Attorney’s fees, expert witness fees and deposition costs are the largest variable and are not published by the state. Check with the Probate Court district handling the estate or a licensed Connecticut attorney for a case-specific estimate. |
The Deadline to Contest a Will in Connecticut
The window is short in some states and long in others, and it is measured from a specific event rather than from the day you learned about the will. That is why the first thing to find out is the date the will was admitted and whether you received formal notice. If the deadline has not run, everything else on this page is available to you.
If it has, the remaining options are narrow and usually involve proving you never got the notice the law required.
Grounds to Contest a Will in Connecticut
Recognized grounds in Connecticut include (1) lack of testamentary capacity — the testator must be 18 or older and of sound mind, meaning able to know the nature and extent of the estate, the natural objects of their bounty, and the manner of distributing the property (Conn. Gen.
Stat. § 45a-250); (2) undue influence; (3) fraud; (4) duress/coercion; (5) improper execution — a will must be in writing, subscribed by the testator, and attested by 2 witnesses each subscribing in the testator’s presence (Conn. Gen.
Stat. § 45a-251); (6) forgery; (7) revocation — by burning, canceling, tearing or obliterating by the testator or by a person authorized in the testator’s presence, or by a later valid will or codicil (Conn. Gen. Stat. § 45a-257); (8) mistake; and (9) that a later will exists.
Who has to prove what: Preponderance of the evidence throughout. On the statutory issues of due execution and testamentary capacity, the burden of proof rests on the PROPONENT of the will, even if the contestant affirmatively pleads lack of capacity or improper execution — Berkeley v. Berkeley, 152 Conn. 398, 401 (1965).
The proponent makes a prima facie case by putting the will and the record of probate into evidence, after which the burden of going forward shifts to the contestant. On undue influence and fraud, the burden rests on the CONTESTANT who alleges it.
Connecticut recognizes a burden-shifting exception: where a stranger standing in a relationship of trust and confidence to the testator is a principal beneficiary and the natural objects of the testator’s bounty are excluded, the burden shifts to that beneficiary to disprove undue influence — but that exception does not apply where the principal beneficiary is the testator’s own child.
Who Can Contest a Will in Connecticut
“Any person aggrieved by any order, denial or decree of a Probate Court” may appeal (Conn. Gen. Stat. § 45a-186(a)). Connecticut courts define aggrievement as a specific, personal and legal interest in the subject matter of the decree that has been specially and injuriously affected — a general interest common to all members of the community is not enough.
In practice this means intestate heirs who would take more without the will, beneficiaries named in the will, beneficiaries under a prior or later will or codicil, a surviving spouse asserting statutory rights, and fiduciaries acting for those parties. Aggrievement must be pleaded and proved; it is jurisdictional. Ordinary estate creditors generally are not aggrieved by admission of a will because their claims are paid regardless of who inherits.
Being unhappy with the will is not standing; losing something because of it is. Check the earlier will and the intestate rules for Connecticut before filing, because they decide whether you are an interested person.
No-Contest Clauses in Connecticut
YES, with a good-faith/probable-cause exception. Connecticut recognizes the validity of a forfeiture (in terrorem) clause in a will, but will not enforce it where the contest was begun in good faith and with probable cause and reasonable justification — South Norwalk Trust Co. v. St. John, 92 Conn. 168, 177 (1917). Connecticut has no statute codifying this; it remains common law.
Connecticut courts have continued to apply the rule in the trust context, including for good-faith challenges to fiduciary conduct (see Salce v. Cardello, 348 Conn. 90 (2023)). Because “probable cause” is decided after the fact by a court, a beneficiary considering a contest may want to have counsel evaluate the risk first.
The Steps to Contest a Will in Connecticut
Step one is the deadline check above. Step two is evidence: the medical records around the signing date, the names of the witnesses, the drafting lawyer’s file, and the financial records that show who benefited.
Step three is the filing — Stage 1 is an “Objection to Admission of Will” (a written objection/appearance filed in the Probate Court district where the estate is pending, in response to the PC-200 Petition/Administration or Probate of Will; a contested matter then proceeds under a Probate Court scheduling order to a hearing on the record).
Stage 2 is an “Appeal from Probate,” commenced by a complaint/appeal filed in the Superior Court in the judicial district where the Probate Court is located, with a copy filed in the Probate Court and process served on the parties (Conn. Gen. Stat. § 45a-186(a), (c)–(d)).. Step four is discovery and, in most cases, a settlement conference; the small minority that reach trial are decided by the judge.

Settling Instead of Fighting
YES. Connecticut Probate Courts operate a statewide voluntary mediation program in which the mediators are current or retired probate judges (see ctprobate.gov mediation program). Connecticut also permits mutual distribution agreements as a family-settlement mechanism: for testate estates under Conn. Gen. Stat. § 45a-434 and Connecticut Probate Court Rules of Procedure § 30.17(b), and for intestate estates under Conn. Gen. Stat. § 45a-433(b) and Rule § 30.17(a).
Many contested Connecticut estates can be resolved this way faster and at lower cost than a full trial, though the court must approve and the agreement generally requires the consent of all affected parties.
Other Connecticut rules: (1) No ante-mortem/pre-death will validation — Connecticut has no living-probate statute; a will can only be challenged after the testator’s death. (2) Self-proving affidavit: under Conn. Gen.
Stat. § 45a-285, attesting witnesses may sign a sworn affidavit before an officer authorized to administer oaths, written on the will or on paper attached to it, and the Probate Court accepts that sworn statement as if the testimony had been taken in court — this can remove the need for live witness testimony on due execution.
(3) Two-stage structure: Connecticut contests start as an objection in the Probate Court, not as a separate civil lawsuit, and reach the Superior Court only by appeal. (4) Scope of the appeal is fixed by the reasons of appeal; the Superior Court may not consider issues outside them. (5) Appeals from matters heard on the record are decided on the probate record rather than as a full new trial (Conn.
Gen. Stat. § 45a-186a, § 45a-186(f)–(h)); appeals from matters not heard on the record are tried de novo. (6) Conn. Gen. Stat. § 45a-128 lets a Probate Court reconsider, modify or revoke its own order or decree in limited circumstances, which is sometimes an alternative to appeal.
(7) Holographic (handwritten, unwitnessed) wills executed in Connecticut are not valid — § 45a-251 requires 2 witnesses — though § 45a-251 also allows a will validly executed under the law of the place where it was executed or where the testator was domiciled. (8) Nuncupative (oral) wills are not recognized.
(9) Connecticut has no elective-share statute of the common percentage type; a surviving spouse instead may claim a statutory life use of one-third of the value of the decedent’s property (Conn. Gen. Stat. § 45a-436), which is sometimes a better path than a contest.
The Evidence That Wins or Loses a Will Contest
Capacity cases turn on the weeks around the signing: the medical chart, prescriptions, a dementia diagnosis, and what the drafting lawyer and the witnesses saw that day. A will signed in a lawyer’s office with two disinterested witnesses and a self-proving affidavit is hard to attack; a will signed at a kitchen table with the main beneficiary present is not.
Undue influence cases turn on the relationship — who drove the parent to the appointment, who chose the lawyer, who was in the room, and whether the new will departed sharply from earlier ones and from what the parent said to other people.
Improper execution is the narrowest ground and the cleanest: Connecticut sets exact witness and signature rules, and a will that misses them fails regardless of what the signer intended. Before you contest a will in Connecticut, gather the prior wills, the medical releases, and the names of everyone at the signing.
Most of that evidence has to be requested formally once the case is filed, and the deadline does not wait for it.
What to Expect When You Contest a Will in Connecticut
A will contest is a lawsuit about the document, not about fairness. When you contest a will in Connecticut, the court asks whether the person who signed it had capacity, signed it freely, and signed it correctly. It does not ask whether the split was reasonable. That is why the strongest cases rest on medical records and witness accounts from the weeks around the signing.
Most families who contest a will in Connecticut settle. Courts encourage it, many states have family settlement rules that let the heirs agree to a different division, and a settlement avoids the cost and delay of trial. The deadline, the grounds, and the no-contest clause above are the three facts that set your bargaining position before any of that begins.
