Online tools usually rely on general inputs (age, income, dependents) and then apply broad assumptions. In Duarte, the biggest drivers are often case-specific proof, such as:
- How the collision or incident happened (and whether the other party’s conduct clearly violated a duty)
- Whether the death was caused by the incident versus a preexisting condition
- What evidence survives (camera footage, phone data, maintenance or training records)
- Comparative fault—California allows parties to be assigned percentages of responsibility, which can reduce recovery
Even two families with similar losses can see very different outcomes depending on the evidence available and how clearly causation is established.
