It can raise or reduce the dollar value of a case because it pays for harm to a close family relationship, not just the injured person's medical bills or lost wages. Technically, loss of consortium is a derivative claim for the loss of a spouse's companionship, affection, assistance, sexual relations, and other benefits of the marital relationship after another person's wrongful act causes serious injury or death.

Because it is derivative, the claim rises or falls with the underlying personal injury or wrongful death case. If liability is weak, or if the injured person's recovery is reduced by comparative fault, the consortium claim is reduced the same way. In practical terms, that means a severe crash or crushing workplace injury in Wichita may support substantial consortium damages only if the defendant is legally responsible and the evidence shows a real change in the marriage.

Kansas treats this carefully. For a death case, family relationship losses are generally recovered within the wrongful death action under K.S.A. 60-1901 and 60-1903, including nonpecuniary losses such as loss of society, companionship, comfort, or protection. Kansas caps wrongful-death nonpecuniary damages at $250,000 under K.S.A. 60-1903 (2024). The usual filing deadline is 2 years under K.S.A. 60-513 (2024). In a nonfatal injury case, a spouse may pursue loss of consortium as a separate but derivative damages claim tied to the injured spouse's lawsuit.
