RE: DOG BITE CLAIM - SETTLEMENT DEMAND
Our Client: [Client Full Name]
Date of Attack: [Date of Attack]
Location of Attack: [Address where attack occurred]
Dog Owner: [Dog Owner Name]
Dog Breed/Description: [Breed, Size, Color]
Claim Number: [If assigned]
Homeowner's Policy Number: [If known]


Dear [Recipient Name]:

This firm represents [Client Name] ("Claimant") for the serious and permanent injuries sustained as a result of a vicious dog attack that occurred on [Date of Attack] in [County] County, Illinois. The attack was perpetrated by a [Breed] dog owned by [Dog Owner Name]. This letter constitutes our formal demand for settlement under Illinois law.


I. ILLINOIS-SPECIFIC LEGAL FRAMEWORK

A. Statute of Limitations

Under 735 ILCS 5/13-202, an action for damages for injury to the person generally must be commenced within two (2) years after the cause of action accrues. The statute does not itself make the injury date the accrual date in every case. Record the attack date, determine claim-specific accrual and tolling under controlling authority, and calculate the deadline: [Expiration Date].

B. Illinois Strict Liability - 510 ILCS 5/16 (Animal Control Act)

Illinois is a strict liability state for dog bites and attacks. Under Section 16 of the Illinois Animal Control Act (510 ILCS 5/16):

"If a dog or other animal, without provocation, attacks, attempts to attack, or injures any person who is peaceably conducting himself or herself in any place where he or she may lawfully be, the owner of such dog or other animal is liable in civil damages to such person for the full amount of the injury proximately caused thereby."

C. Key Elements Under Illinois Strict Liability

Under 510 ILCS 5/16, a plaintiff must prove:

  1. Injury caused by the dog (bite or other attack);
  2. Lack of provocation by the injured person;
  3. Peaceable conduct by the injured person; AND
  4. Lawful presence of the injured person at the location.

No proof of prior viciousness or owner knowledge is required. By eliminating the common-law "one-bite" rule, the Act imposes strict liability on dog owners once the four statutory elements are shown. Steinberg v. Petta, 114 Ill. 2d 496 (1986).

D. Illinois Comparative Negligence

For a separately pleaded action based on negligence, 735 ILCS 5/2-1116 bars recovery when plaintiff contributory fault is more than 50% of the injury's proximate cause and otherwise reduces damages proportionally. The section's text applies to negligence and strict-products-liability actions; do not automatically import that framework into the distinct 510 ILCS 5/16 statutory count. Analyze provocation under § 16 and comparative fault under the precise theory pleaded.

Our client bears absolutely no responsibility for this attack.

E. Relevant Illinois Case Law

  • Robinson v. Meadows, 203 Ill. App. 3d 706 (1990) - Statement of the four statutory elements of liability under 510 ILCS 5/16
  • Steichman v. Hurst, 2 Ill. App. 3d 415, 275 N.E.2d 679 (1971) - Statutory and common-law remedies are concurrent; the Act reaches injuries beyond bites (fall/knockdown)
  • Nelson v. Lewis, 36 Ill. App. 3d 130 (1976) - "Provocation" may be intentional or unintentional
  • Docherty v. Sadler, 293 Ill. App. 3d 892 (1997) - A person who cares for or has custody of the dog is an "owner" outside the Act's protected class
  • Steinberg v. Petta, 114 Ill. 2d 496, 501 N.E.2d 1263 (1986) - "Owner" requires care, custody, or control; an absentee landlord who merely permits a tenant's pet is not liable

II. PRESERVATION OF EVIDENCE NOTICE

YOU ARE HEREBY DIRECTED TO PRESERVE ALL EVIDENCE relating to this attack and the subject animal, including but not limited to:

  • ☐ The animal itself (do not destroy, euthanize, or transfer without notice to our office)
  • ☐ All veterinary records for the animal
  • ☐ Vaccination records, including rabies vaccination
  • ☐ Animal licensing and registration documents
  • ☐ [County] County Animal Control records
  • ☐ All photographs or videos of the animal
  • ☐ Prior bite reports or complaints regarding this animal
  • ☐ Prior aggressive incidents involving this animal
  • ☐ Any "dangerous dog" or "vicious dog" designations
  • ☐ Communications with animal control or authorities
  • ☐ Homeowner's or renter's insurance policies
  • ☐ Any liability exclusions or breed-specific riders
  • ☐ Lease agreements (if renting) and any pet policies
  • ☐ Training records for the animal
  • ☐ Proof of confinement measures (fencing, leash, muzzle)

Illinois does not recognize spoliation as an independent tort. Negligent spoliation proceeds, if at all, under ordinary negligence and requires a preservation duty, breach, causation, and damages. Boyd v. Travelers Insurance Co., 166 Ill. 2d 188, 194-96 (1995). Please preserve available records and evidence; any remedy depends on the facts and applicable litigation rules.


III. STATEMENT OF FACTS

A. The Attack

On [Date of Attack], at approximately [Time], our client was [describe activity - e.g., "walking on the public sidewalk in front of [Address]," "visiting the dog owner's residence as an invited guest," "delivering mail as a United States Postal Service carrier," "in [his/her] own yard," etc.] in [City], [County] County, Illinois.

At that time, [Dog Owner Name]'s [Breed] dog [describe how attack occurred - e.g., "escaped from the owner's property through an unsecured gate," "was off-leash in violation of the [City/County] leash ordinance," "broke free from its leash when the owner lost control," "attacked without warning or provocation," etc.].

The dog attacked our client viciously and without provocation. [Describe the attack in detail]:

[Example: "The dog lunged at our client, knocked [him/her] to the ground, and bit [him/her] repeatedly on the [body parts affected]. Our client attempted to protect [himself/herself] but was unable to fend off the animal. The attack lasted approximately [duration] before [describe how attack ended]."]

B. Statutory Elements Under 510 ILCS 5/16

1. Injury by Dog: The dog owned by [Dog Owner Name] attacked and bit our client, causing the severe injuries documented herein.

2. No Provocation: Our client did absolutely nothing to provoke this attack. [He/She] did not tease, torment, abuse, or antagonize the dog in any way. Illinois defines provocation as "an act or process of provoking, stimulation or incitement," and it may be either intentional or unintentional. Nelson v. Lewis, 36 Ill. App. 3d 130 (1976). Our client engaged in no such conduct.

3. Peaceable Conduct: At the time of the attack, our client was peacefully [describe activity]. [He/She] was not engaged in any aggressive, threatening, or unlawful behavior.

4. Lawful Presence: Our client was lawfully present at the location. [He/She] was:

  • ☐ On a public sidewalk/street
  • ☐ An invited guest on the property
  • ☐ Performing employment duties (mail carrier, delivery person, etc.)
  • ☐ On [his/her] own property
  • ☐ [Other lawful presence]

C. No Provocation Defense Available

Our client did absolutely nothing to provoke this attack. At the time of the incident, our client was:

  • ☐ Peacefully and lawfully present at the location
  • ☐ Not interacting with or approaching the dog
  • ☐ Not engaging in any behavior that could be construed as threatening
  • ☐ Not teasing, tormenting, or abusing the animal
  • ☐ [Not on the dog owner's property / An invited guest on the property]

Illinois defines provocation as "an act or process of provoking, stimulation or incitement," which the courts have held may be either intentional or unintentional. Nelson v. Lewis, 36 Ill. App. 3d 130 (1976). Our client did nothing — intentionally or unintentionally — that stimulated or incited the dog to attack.


IV. LIABILITY ANALYSIS

A. Strict Liability Under 510 ILCS 5/16

Liability is established as a matter of law under Illinois' strict liability statute:

1. Injury by Dog: The dog owned by [Dog Owner Name] attacked and injured our client. Medical records document the injuries.

2. No Provocation: Our client did nothing to provoke the attack.

3. Peaceable Conduct: Our client was peacefully [walking/visiting/working/etc.] at the time.

4. Lawful Presence: Our client was lawfully present at [public sidewalk / private property as invitee / etc.].

Under 510 ILCS 5/16, these elements establish liability regardless of:

  • Whether the dog had ever bitten anyone before
  • Whether the owner knew of any dangerous propensities
  • Whether the owner exercised reasonable care

B. Expanded Scope of Illinois Strict Liability

Illinois' Animal Control Act applies to any injury caused by a dog, not just bites. This includes:

  • Knockdowns and resulting fall injuries
  • Scratches and lacerations
  • Injuries from fleeing from the dog
  • Any other injury "proximately caused" by the dog

See Steichman v. Hurst, 2 Ill. App. 3d 415, 275 N.E.2d 679 (1971).

C. Alternative Negligence Theory

In addition to the statutory count, a separately supported negligence theory may be pleaded when current authority and the facts establish duty, breach, causation, and damages:

Duty: Dog owners owe a duty of reasonable care to prevent their animals from causing harm.

Breach: The owner breached this duty by:

  • ☐ Violating the [City/County] leash law
  • ☐ Failing to properly secure the animal
  • ☐ Failing to maintain secure fencing
  • ☐ Failing to adequately supervise the animal
  • ☐ [Other breaches]

Causation: The breach directly caused our client's injuries.

Damages: Our client suffered substantial damages as detailed below.

D. Ordinance or Statutory-Violation Theory

If relying on a leash or animal-control provision, quote the current text, establish that it applied to this animal, person, place, and event, and determine its civil effect under current controlling authority. Do not label an unidentified or unverified local violation negligence per se.

E. Landlord Liability (If Applicable)

Liability under the Animal Control Act runs only against an "owner," a term the Act defines to include any person who "keeps or harbors" the animal, "has it in his care," "acts as its custodian," or "knowingly permits" the dog to remain on premises occupied by that person. 510 ILCS 5/2.16. A landlord is therefore liable only where the landlord independently qualifies as an "owner" under this definition; the Act "contemplates some degree of care, custody, or control." An absentee landlord who merely allows a tenant to keep a pet is not an "owner" and is not liable under the Act. Steinberg v. Petta, 114 Ill. 2d 496, 501 N.E.2d 1263 (1986).

[Landlord Name] is liable as an "owner" because:

  • ☐ [Landlord Name] kept or harbored the dog, or had it in [his/her] care or custody
  • ☐ [Landlord Name] knowingly permitted the dog to remain on premises [he/she] occupied or controlled
  • ☐ [Describe the specific facts establishing the landlord's care, custody, or control of the dog]

ILLINOIS-SPECIFIC PRACTICE NOTES

  • ☐ Strict Liability State: Illinois imposes strict liability under 510 ILCS 5/16. No need to prove prior viciousness or owner knowledge.

  • ☐ Broad Scope: The statute covers "attacks, attempts to attack, or injures" - not limited to bites.

  • ☐ Provocation Defense: The only real defense is provocation. Document that client did nothing to provoke.

  • ☐ Comparative fault: Apply § 2-1116 to a covered negligence or strict-products-liability count; analyze § 16 provocation separately for the Animal Control Act count.

  • ☐ Landlord Liability: Narrow. A landlord is liable only if [he/she] independently qualifies as an "owner" (care, custody, or control) under 510 ILCS 5/2.16; an absentee landlord who merely permits a tenant's pet is not liable. See Steinberg v. Petta, 114 Ill. 2d 496 (1986).

  • ☐ Venue: Confirm the current venue statute, defendant type and residence, event location, and any transfer issue before selecting the county.

  • ☐ Cook County: If in Cook County, be aware of specific local rules and potential assignment to a particular division.

  • ☐ Local procedure: Check the selected circuit's current local rules and case-management orders for any arbitration, mediation, assignment, or filing requirement.

Demand Letters

Legal authority

  • 510 ILCS 5/16 (animal attack or injury liability)
  • 510 ILCS 5/2.16 (definition of owner)
  • 735 ILCS 5/13-202 (two years after accrual for listed personal-injury actions)
  • 735 ILCS 5/2-1116 (comparative fault for negligence and strict-products-liability actions)

A demand letter is a formal written request to fix a problem or pay what is owed, sent before anyone files a lawsuit. It gives the other side a real chance to settle, creates a record of your attempt to resolve things, and in many cases (unpaid debts, insurance claims, broken contracts) starts a legally required response window. A well-written demand letter lays out what happened, what you want, and a deadline to act, which is often enough to get results without ever going to court.
