Third-party liability insurance stacking is a complex but potentially valuable strategy in Texas personal injury cases. When multiple insurance policies are available, understanding how to properly “stack” these coverages can significantly impact the compensation available to injured parties.
What is Third-Party Liability Insurance?
Third-party liability insurance is coverage that protects policyholders from claims made by others (third parties) for injuries or damages caused by the policyholder. In the context of auto insurance, third-party liability coverage is mandatory in Texas and includes:
- Bodily injury liability (minimum $30,000 per person/$60,000 per accident)
- Property damage liability (minimum $25,000)
The Concept of Insurance Stacking
Insurance stacking refers to combining multiple insurance policy limits to increase the total available coverage for a claim. There are two primary types of stacking:
- Vertical stacking: Applying primary and excess/umbrella policies in sequence
- Horizontal stacking: Combining multiple policies that cover the same risk
Vertical Stacking in Texas Personal Injury Cases
Vertical stacking is the most common form of third-party liability insurance stacking in Texas. Here’s how it typically works:
Primary Auto Liability Policy
The at-fault driver’s auto liability insurance serves as the primary coverage. Texas requires minimum coverage of $30,000 per person and $60,000 per accident for bodily injury.
Secondary/Excess Policies
Once the primary policy limits are exhausted, secondary or excess policies can be accessed. These may include:
- Personal umbrella policies
- Commercial general liability policies (for business vehicles)
- Employer liability policies (if the accident occurred during employment)
Example of Vertical Stacking
Consider a scenario where the at-fault driver has a standard auto policy with $30,000 bodily injury limits and a personal umbrella policy with $1 million in coverage. If the injured party’s damages amount to $500,000, they could potentially recover:
- $30,000 from the primary auto policy
- $470,000 from the umbrella policy
Horizontal Stacking Opportunities in Texas
Horizontal stacking involves combining multiple policies at the same level. While Texas has restrictions on stacking uninsured/underinsured motorist coverages within the same policy, horizontal stacking may be possible in several third-party liability scenarios:
Multiple At-Fault Parties
When multiple parties share fault for an accident, their respective liability policies can effectively be “stacked” to increase available compensation.
Example:
If Driver A runs a red light and hits Driver B, who then strikes your vehicle, both Driver A and Driver B may be partially liable. You could potentially recover from both drivers’ liability policies up to their respective limits.
Business and Personal Policies
When an accident involves someone driving for both personal and business reasons, both personal and commercial policies might apply.
Example:
A salesperson driving their own car for work purposes may have coverage under both their personal auto policy and their employer’s commercial auto or general liability policy.
Vehicle Owner vs. Driver Policies
The vehicle owner’s insurance and the driver’s insurance may both provide coverage in certain scenarios.
Example:
If someone borrows a friend’s car and causes an accident, both the vehicle owner’s policy and the driver’s policy might provide coverage under different circumstances.
Legal Principles Supporting Third-Party Insurance Stacking
Several legal principles support the practice of stacking third-party liability insurance in Texas:
Joint and Several Liability
Under Texas Civil Practice & Remedies Code § 33.013, a defendant who is more than 50% responsible can be held liable for the entire amount of damages, regardless of other parties’ involvement. This allows injured parties to recover from multiple insurance policies.
Pro-Rata Share Rules
When multiple insurers provide coverage for the same loss, Texas follows the “pro-rata share” rule, requiring insurers to contribute proportionally to their policy limits. This provides a legal basis for accessing multiple policies.
“Other Insurance” Clauses
Insurance policies contain “other insurance” clauses that explain how they interact with other applicable policies. Courts often interpret these clauses to allow recovery under multiple policies up to the total damages amount.
Challenges to Successful Insurance Stacking
Anti-Stacking Provisions
Some insurance policies contain explicit anti-stacking language designed to prevent or limit stacking. Texas courts have upheld some anti-stacking provisions, particularly in uninsured/underinsured motorist contexts.
Policy Exclusions
Each policy may contain exclusions that limit coverage in certain scenarios. Common exclusions include:
- Regular use exclusions
- Business use exclusions
- Named driver exclusions
Priority of Payment Disputes
When multiple policies apply, disputes may arise regarding which policy pays first and in what amounts. These disputes often require legal intervention to resolve.
Strategic Approaches to Maximize Recovery
Comprehensive Investigation
A thorough investigation to identify all potential liable parties and applicable insurance policies is crucial. This includes:
- Obtaining police reports
- Interviewing witnesses
- Reviewing employment relationships
- Investigating business entities involved
Policy Analysis
Careful review of all potentially applicable insurance policies is essential, focusing on:
- Coverage limits
- “Other insurance” clauses
- Priority of payment provisions
- Exclusions that might apply
Proper Timing of Settlements
Strategically timing settlements with different insurers can maximize total recovery. In some cases, it’s advantageous to settle with one insurer before proceeding against others.
Recent Texas Case Law on Insurance Stacking
Texas courts have addressed various aspects of insurance stacking in recent decisions:
- The Texas Supreme Court has generally upheld the validity of anti-stacking provisions in uninsured/underinsured motorist policies but has been more flexible regarding third-party liability stacking.
- Lower courts have recognized the applicability of multiple liability policies in cases involving commercial and personal use overlaps.
Steps to Effectively Stack Third-Party Liability Insurance
- Identify all potentially liable parties (drivers, vehicle owners, employers, businesses)
- Locate all applicable insurance policies for each potentially liable party
- Analyze each policy for coverage limits, exclusions, and “other insurance” clauses
- Document damages thoroughly to justify recovery beyond primary policy limits
- Present strategic demands to each insurer, clearly outlining your legal theory for stacking
- Address denials and coverage disputes through proper legal channels
