A survival action, not a separate statutory claim
Iowa Code §611.20 lets all causes of action survive death — so a fatal injury claim continues as the decedent's own claim, now pursued through the estate (via §611.22), rather than creating a brand-new statutory action for named beneficiaries the way many states' dedicated wrongful death acts do.
Under Iowa Code §633.336, the recovery is generally disposed of as personal property of the estate — but when the damages include loss of services and support of a deceased spouse, parent, or child, the court apportions that specific category among the surviving spouse, children, and parents as it deems equitable, rather than by a fixed statutory formula.
