Some personal injury cases involve one clearly responsible person. A driver runs a red light, strikes another vehicle, and causes an injury. Other cases are far more complicated.
A chain-reaction collision on I-15 may involve several careless drivers. A construction accident may result from decisions made by a property owner, general contractor, subcontractor, and equipment supplier. A defective vehicle component may contribute to injuries that were also caused by a negligent driver.
When multiple parties share responsibility, Utah law allows fault to be divided among the people and entities whose conduct contributed to the injury. The percentage assigned to each party can directly affect how much compensation an injured person may recover and who must pay it.
Steele Adams Hosman investigates Utah personal injury claims to identify every potentially responsible party, preserve evidence, and challenge attempts to unfairly shift blame to the injured person.
What Does “Multiple-Party Liability” Mean?
Multiple-party liability means that more than one person, business, government entity, or other organization may have contributed to the same injury.
The parties do not need to have committed the same type of wrongdoing. Their separate actions or failures may combine to cause one accident or worsen its consequences.
Potentially responsible parties could include:
- Two or more drivers
- A commercial trucking company
- A driver’s employer
- A vehicle owner
- A property owner
- A property management company
- A general contractor
- A subcontractor
- A product manufacturer
- A maintenance provider
- A government agency
- The injured person
- A person or entity that cannot legally be sued
Utah defines “fault” broadly. The definition includes an actionable breach of a legal duty that caused or contributed to an injury, including negligence, comparative negligence, strict liability, product liability, breach of warranty, assumption of risk, and product misuse or modification.
This broad definition allows a court or jury to examine the conduct of everyone who may have contributed to the harm.
How Does Utah Divide Fault Among Multiple Parties?
Utah uses a comparative fault system. Instead of treating responsibility as an all-or-nothing issue, a fact finder may assign a percentage of fault to each person or organization whose conduct contributed to the injury.
The percentages should total 100%.
For example, imagine a crash involving three vehicles on I-80. The evidence shows:
- Driver A was speeding and assigned 50% of the fault.
- Driver B changed lanes without checking and received 30%.
- The injured driver was distracted and received 20%.
If the injured driver’s proven damages total $200,000, the injured driver’s own 20% share of fault would generally reduce the recoverable amount by $40,000. The remaining damages would be allocated according to the applicable Utah rules.
Utah law permits the fact finder to allocate fault to the person seeking compensation, each defendant, certain immune persons, and properly identified nonparties when a factual and legal basis exists for doing so.
The percentages are not supposed to be guesses. They should be supported by evidence showing what each party did, what duty applied, and how that conduct contributed to the accident.
Can You Recover Compensation If You Were Partly at Fault?
Possibly. Utah does not automatically bar recovery merely because the injured person contributed to the accident.
Under Utah Code Section 78B-5-818, an injured person may recover from a defendant or group of defendants when their combined fault, together with fault attributed to specified immune persons and nonparties, exceeds the injured person’s fault.
This is frequently described as a modified comparative negligence rule.
In practical terms, an injured person whose percentage of fault is lower than the relevant combined opposing fault may still recover damages, although the recovery is reduced to reflect the injured person’s share of responsibility.
An injured person whose fault reaches the statutory cutoff may be unable to recover.
Consider two examples:
Example One: The Injured Person Is 20% Responsible
A driver approaches an intersection on 700 East slightly above the speed limit. Another motorist turns left directly into the driver’s path.
A jury assigns:
- 80% fault to the turning motorist
- 20% fault to the injured driver
If the damages total $100,000, the injured driver’s share would generally reduce the recovery by $20,000.
Example Two: The Injured Person Is Equally Responsible
Suppose the evidence instead supports assigning 50% of the fault to the injured driver and 50% to the other driver.
That allocation may prevent the injured driver from recovering under Utah’s comparative negligence rule because the opposing fault does not exceed the injured person’s fault.
Small differences in fault percentages can therefore have major financial consequences.
When an insurance company claims you contributed to an accident, do not accept its percentage as final. Contact Steele Adams Hosman for a free consultation and an independent review of the evidence.
Does Each Defendant Have to Pay the Entire Judgment?
Usually not. Utah generally limits each defendant’s financial liability to the proportion of damages corresponding to that defendant’s assigned percentage of fault.
Utah Code Section 78B-5-820 states that the maximum amount for which a defendant may be liable is the percentage or proportion of damages equal to the fault attributed to that defendant. The statute also provides that a defendant is not entitled to contribution from another person.
This rule is often referred to as several liability.
Suppose an injured person suffers $500,000 in damages, and the jury allocates fault as follows:
- Truck driver: 40%
- Trucking company: 35%
- Maintenance contractor: 15%
- Injured person: 10%
After accounting for the injured person’s share, the remaining defendants would generally be responsible only for the portions corresponding to their assigned fault.
That could mean:
- Truck driver: $200,000
- Trucking company: $175,000
- Maintenance contractor: $75,000
This structure makes identifying every potentially responsible party critically important. If one responsible business is never identified or included, the injured person may not be able to collect that party’s portion from another defendant.
Why Is Identifying Every Responsible Party So Important?
An accident may appear to involve one negligent person while the investigation reveals additional causes.
For example, a commercial truck driver may cause a crash by failing to stop in traffic. Further investigation could show that:
- The trucking company encouraged unsafe schedules.
- A maintenance contractor failed to repair worn brakes.
- The cargo was improperly loaded by another business.
- A parts manufacturer sold a defective braking component.
- Another driver abruptly entered the truck’s lane.
Each party may owe a different legal duty and may have separate insurance coverage.
Identifying all responsible parties may:
- Increase the available insurance coverage
- Prevent one defendant from shifting all blame to an absent party
- Provide access to additional records and witnesses
- Reveal corporate safety failures
- Protect the injured person from an artificially low allocation of fault
- Improve the ability to collect an eventual settlement or judgment
Steele Adams Hosman examines the entire sequence of events rather than assuming that the most visible person is the only responsible party.
Can Fault Be Assigned to Someone Who Is Not Named as a Defendant?
Yes, under certain circumstances.
Utah law allows fault to be allocated to certain nonparties when they are properly identified and there is a factual and legal basis to find that their conduct contributed to the injury. The court may also allocate fault to a person who is immune from suit.
This can create a major challenge for injured people.
A defendant may argue that an absent person, unidentified driver, employer, contractor, or other nonparty deserves part of the blame. If fault is allocated to that nonparty, the percentage assigned may reduce the amounts attributed to the defendants who can actually be required to pay.
For example, a property owner sued after a fall may claim that a snow-removal contractor caused the dangerous ice. The contractor may not yet be part of the case. Unless the injured person investigates the contract and adds the contractor when appropriate, some fault could potentially be assigned to an entity from which no recovery is obtained.
Utah requires a factual and legal basis before fault may be assigned. A defendant should not be allowed to blame a nonparty based only on speculation.
What Is an Immune Party?
An immune party is a person or entity that may have contributed to an injury but cannot be sued for damages in that particular action because a law provides immunity.
Examples may include:
- An employer protected by workers’ compensation exclusivity
- A government entity protected by governmental immunity
- A government employee whose conduct falls within an immunity provision
Fault allocated to an immune person may still be considered when determining the comparative responsibility of the injured person and the defendants. However, the allocation itself does not make the immune person financially liable in that case.
Imagine that a construction worker is injured because of combined failures by the worker’s employer, a general contractor, and an equipment manufacturer.
The employer may be protected from an ordinary negligence lawsuit by workers’ compensation rules. Even so, the employer’s conduct could become part of the fault-allocation analysis while the worker pursues third-party claims against the contractor or manufacturer.
Cases involving immune parties can be particularly complicated because Utah law also contains rules addressing how certain percentages of immune-party fault may be reallocated.
How Are Damages Calculated in a Multiple-Party Case?
A fact finder may first determine the total amount of damages without reducing the number for comparative fault.
Those damages may include:
- Past medical expenses
- Future medical care
- Lost wages
- Diminished earning capacity
- Pain and suffering
- Emotional distress
- Physical impairment
- Disfigurement
- Loss of enjoyment of life
- Property damage
- Household assistance
The court or jury then determines the percentage of fault assigned to the injured person and each responsible party. Utah law permits the use of separate special verdicts identifying total damages and the proportion of fault assigned to each person or entity.
Consider the following scenario:
- Total damages: $300,000
- Injured person: 10% at fault
- Defendant One: 60% at fault
- Defendant Two: 30% at fault
The injured person’s damages would first be reduced by the 10% personal fault allocation, leaving $270,000. Defendant One’s share would generally correspond to $180,000, and Defendant Two’s share would correspond to $90,000.
These calculations become more complex when the case includes:
- Settling defendants
- Immune parties
- Nonparties
- Unidentified vehicles
- Multiple injured people
- Limited insurance coverage
- Disputed future damages
Steele Adams Hosman can evaluate how each proposed allocation may affect both the total recovery and the practical ability to collect it.
A case involving multiple responsible parties requires more than filing a claim against the first insurer involved. Let Steele Adams Hosman investigate every source of fault and insurance coverage.
What Types of Utah Injury Cases Commonly Involve Multiple Parties?
Multiple-party responsibility can arise in nearly every area of personal injury law.
Multi-Vehicle Car Accidents
Chain-reaction crashes may involve several drivers who were speeding, following too closely, distracted, or making unsafe lane changes.
Commercial Truck Accidents
A truck crash may involve the driver, carrier, maintenance company, cargo loader, broker, vehicle owner, or parts manufacturer.
Construction Accidents
A worker, pedestrian, or visitor may be harmed by the combined negligence of a property owner, general contractor, subcontractor, equipment operator, architect, or supplier.
Premises Liability Claims
Responsibility for an unsafe condition may be shared by a building owner, tenant, property manager, maintenance company, or snow-removal contractor.
Defective Product Claims
An unsafe product may involve a manufacturer, distributor, seller, component supplier, or negligent user.
Rideshare Accidents
Potentially responsible parties may include a rideshare driver, another motorist, a vehicle owner, and one or more insurance carriers.
Bicycle and Pedestrian Accidents
A negligent driver may be primarily responsible, while dangerous road design, a construction obstruction, or another road user also contributes to the collision.
Medical and Emergency Transport Incidents
Different providers, facilities, contractors, or product manufacturers may contribute to the same injury.
The existence of multiple parties should not be assumed, but it should always be considered when the circumstances suggest more than one contributing cause.
What Evidence Helps Determine Each Party’s Percentage of Fault?
Fault allocation depends on evidence explaining how the accident happened and what each participant did.
Useful evidence may include:
- Police reports
- Accident-scene photographs
- Surveillance recordings
- Traffic camera footage
- Dashcam video
- Witness statements
- Vehicle event data
- Cellphone records
- Electronic logging-device information
- Truck inspection records
- Maintenance records
- Employment and training files
- Contracts and lease agreements
- Property inspection logs
- Construction safety documents
- Product design and testing records
- Expert reconstruction analysis
- Medical records
In a highway collision, an accident reconstruction professional may analyze vehicle damage, tire marks, electronic data, road conditions, and sight distances.
In a premises liability case, maintenance contracts may show which business was responsible for cleaning a floor, repairing a stairway, or removing snow.
In a product case, internal records may reveal whether a manufacturer knew about a dangerous defect.
Evidence can be lost quickly. Vehicle data may be overwritten, surveillance footage may be erased, and damaged products may be repaired or discarded.
Prompt preservation efforts may determine whether another responsible party can be identified and held accountable.
What If One Responsible Party Has No Insurance?
An uninsured or underinsured defendant can complicate recovery.
Even if a person is assigned a large percentage of fault, a judgment may have limited practical value if that person has no insurance and no assets from which payment can be collected.
Other possible sources of compensation may include:
- The injured person’s uninsured motorist coverage
- Underinsured motorist coverage
- An employer’s commercial policy
- A vehicle owner’s policy
- An umbrella insurance policy
- A corporate defendant’s liability coverage
- Product liability coverage
- Property insurance
- Government coverage or risk-management programs
The existence of an uninsured defendant does not automatically increase another defendant’s percentage. Fault must still be determined according to the evidence and Utah law.
This is another reason every potentially responsible party and policy should be investigated early.
Can One Defendant Blame Another During Settlement Negotiations?
Yes. Blame-shifting is common when several insurance carriers are involved.
One carrier may claim that:
- Another driver caused the initial impact
- A contractor created the hazard
- A manufacturer produced a defective component
- The injured person caused most of the accident
- An unidentified vehicle forced its insured to react
- A government entity created a dangerous road condition
Each insurer may offer only the amount it believes corresponds to its insured’s fault. This can delay settlement when the parties disagree about responsibility.
Steele Adams Hosman can compare the carriers’ positions with the physical evidence, witness testimony, and governing legal duties.
When insurers refuse to accept a reasonable share of responsibility, filing a lawsuit may allow Steele Adams Hosman to obtain records through discovery, question witnesses under oath, and present the allocation issue to a jury.
Should You Settle With One Party Before the Others?
Sometimes resolving part of a case is appropriate, but settling with one defendant can affect the remaining claims.
Before accepting a partial settlement, the injured person should understand:
- Which claims are being released
- Whether the release protects additional parties
- How the settlement affects fault allocation
- Whether medical liens have been addressed
- Whether enough insurance remains to cover future losses
- Whether the settling party will continue cooperating
- How Utah law treats settling defendants at trial
A broadly written release may unintentionally end claims against parties that were not intended to be released.
An injured person should not sign a settlement agreement merely because one insurance carrier offers quick payment. Steele Adams Hosman can review how the proposal affects the entire case.
What Should You Do After an Accident Involving Multiple Parties?
Take the following steps when possible:
- Obtain medical care. Your health and medical documentation should come first.
- Report the accident. Contact law enforcement, a property manager, an employer, or the appropriate authority.
- Document the entire scene. Photograph every involved vehicle, property condition, road feature, and visible injury.
- Identify all witnesses. Obtain contact information before people leave.
- Collect information from every involved party. Do not focus only on the person who appears most responsible.
- Preserve physical evidence. Keep damaged products, clothing, helmets, vehicle parts, or other relevant items.
- Avoid assigning blame at the scene. Do not speculate about percentages of responsibility.
- Do not give multiple recorded statements without legal guidance. Each insurer may attempt to obtain separate admissions.
- Save every document. Keep reports, bills, insurance letters, contracts, photographs, and medical records.
- Contact Steele Adams Hosman promptly. Early investigation can help identify parties before evidence disappears.
Frequently Asked Questions About Multiple Responsible Parties
Can I sue more than one person for the same injury?
Yes, when more than one person or entity had a legal duty and their conduct contributed to the injury. Each claim must have a factual and legal basis.
Will one insurance company pay everything?
Not necessarily. Utah generally limits a defendant’s responsibility to the percentage of damages corresponding to that defendant’s assigned fault.
What if I do not know who all the responsible parties are?
That is common early in a case. Investigation, document requests, expert review, and litigation discovery may reveal additional parties.
Can the jury assign fault to someone who is not in court?
In certain circumstances, yes. Utah law allows allocation to properly identified nonparties when there is a factual and legal basis for doing so.
Can I recover if I was partly responsible?
Possibly. Your ability to recover depends on how your fault compares with the fault attributed to the defendants and other parties considered under Utah law.
What if another responsible person cannot be sued?
That person’s fault may still affect the allocation analysis, even though the allocation does not make the immune person financially liable.
Who decides each percentage of fault?
If the case goes to trial, the judge or jury may determine total damages and assign percentages through special verdict findings.
Contact Steele Adams Hosman About a Complex Utah Injury Claim
When several parties contribute to an injury, the case can quickly become a dispute over percentages, insurance policies, and missing defendants. Each insurance company has an incentive to minimize its own responsibility and place more blame elsewhere.
A careful investigation can reveal that responsibility extends beyond the person immediately involved in the accident. Employers, contractors, property owners, maintenance businesses, manufacturers, and other parties may also have contributed to the harm.
