Wildfires

Most wildfires are treated as acts of nature, but many are started by people or equipment: a utility's power lines, a railroad, a contractor's machinery, or someone burning debris. When a wildfire has a human cause, one event can destroy hundreds or thousands of homes, so these files usually become group claims, often handled alongside other carriers through law firms that specialize in wildfire subrogation. The rules vary a lot by state and are changing, so check current law early.

Hands off until the expert arrives. Nothing at the scene gets touched, moved, repaired, or thrown out until the origin and cause investigator has secured it. Evidence that's moved early can sink the whole recovery.

1. Identify

Common human causes of wildfires

  • Utility power lines: lines that fall or slap together in wind, equipment that fails, or trees growing into lines the utility was supposed to trim
  • Railroads: sparks from brakes or wheels, and track work
  • Contractors and equipment: mowers, grinders, welding, and other work that throws sparks in dry grass
  • Debris burning or campfires that get away
  • Vehicles: a dragging trailer chain or a hot exhaust parked in dry grass
  • Fireworks
  • Arson, which usually leaves no one to recover from

Who may be responsible

What you find Likely cause Who may be responsible
Fire started near power lines during high wind Utility equipment or lines The electric utility
Trees or branches contacted lines Poor vegetation management The utility, and its tree-trimming contractor
Fire started along railroad tracks Sparks from trains or track work The railroad
Fire started where crews were working Sparks from equipment The contractor, and whoever hired them
Fire started from a burn pile or campfire Escaped fire The person who set it, and their homeowners or liability carrier
Fire started on public land from a controlled burn Escaped prescribed burn The government agency that ran it

Responsible parties to consider

  • The electric utility, and its tree-trimming and maintenance contractors
  • A railroad
  • Contractors, and the property owners who hired them
  • Neighbors or landowners who burned debris
  • Government agencies, for escaped controlled burns or their own equipment
  • Equipment manufacturers, if a product failed

Government deadlines can be very short. When the responsible party is a government agency or a publicly owned utility, most states require a written claim first, often within months of the fire, before you can sue. Federal agencies have their own claim process under the Federal Tort Claims Act. Missing that deadline can end the claim, so check it on day one.

Utility liability rules differ by state. Some states, like California, have made utilities responsible for fires their equipment causes even without proving negligence, under a rule called inverse condemnation. Other states require proof of negligence, and some have passed laws that limit what utilities pay. In 2026, California began debating limits on insurers' recovery from utilities, so confirm the current rules before relying on them.

2. Notify and investigate

You usually won't run your own scene exam. Wildfire scenes are huge and controlled by fire agencies. The official investigation, the utility's own reports to regulators, and the lawsuits that follow are where the cause gets proven. Your job is to document your insured's loss well and make sure your claim is filed on time.

Consider joining a group. When one fire causes many losses, carriers often pursue the claim together through a law firm that specializes in wildfire subrogation. This splits expert and legal costs across many carriers. Ask your client how it handles these.

Finding the utility's claims contact. Look the power company up in the Subrobuddy Utility Directory and add it to your letter with the Party Finder. Most large utilities take claims through an online form or phone line, so file there first and reference the claim number in your notice.

Who to put on notice

  • The utility, railroad, contractor, agency, or person believed to be responsible
  • Their carriers, once known
  • The government agency, through its formal claim process, if one is involved

Evidence checklist

3. Demand, negotiate, and settle

Liability theories

  • Against a utility: negligence, and in some states, inverse condemnation, which doesn't require proving negligence
  • Against a railroad or contractor: negligence, and in some states, fire-specific laws that make whoever starts a fire responsible for the damage
  • Against a person who burned debris: negligence, and violation of burn bans or permits
  • Against a government agency: negligence, through the state's claims process or the Federal Tort Claims Act

Defenses to expect

Defense How to answer it
It was an act of nature The official cause report, and evidence tying the start to equipment or people
Your claim is late Proof you filed on time. This is why the government deadline check comes first.
State law limits what we pay Check the current law for that state and that fire date. Rules have changed recently.
The fire had several starts, and ours didn't reach your insured Fire spread maps and timing, usually from the group's experts
Your insured's damage came from smoke, not fire Smoke and ash damage is still damage caused by the fire. Document it the same way.

Negotiating and settling

  • Many utility wildfire cases end in large group settlements or settlement funds, often after years. Keep the file organized so you can file quickly when a program opens.
  • Settlement programs may pay carriers a percentage of what they paid, rather than the full amount. Know your client's approval rules before agreeing.
  • Review the release with the release checklist, then close with the standard closing letter and the deductible reimbursement letter.
