The most significant cause in determining liability for a loss is referred to as proximate cause. Proximate cause is a legal concept that establishes the primary reason or event that set into motion the chain of events leading to a loss. This means it directly relates to the incident for which liability is being assessed. In the context of insurance, understanding proximate cause is essential because it helps to determine whether the insurer is liable for a particular claim.

For example, if a fire (the proximate cause) led to significant property damage, the insurance company would look at this cause to evaluate whether the claim is valid under the terms of the policy.

Other types of causes, such as remote, dominant, or indirect causes, may play a role in the broader context of an event, but they do not directly establish liability in the same clear and significant way that proximate cause does. These other causes may refer to factors that contributed to the situation but do not directly link to the immediate loss or damage for which liability is determined.
