Modifies provisions relating to wrongful death actions

HB 2164 modifies Missouri's wrongful death law by replacing Section 537.080 with new language that clarifies who can file such lawsuits. It specifies that claims must be brought first by a spouse, children, or parents; if none exist, then by siblings (or their descendants) regardless of prior parental rights termination; and finally by a court-appointed representative if no eligible family members remain. The bill also states only one lawsuit may be filed against a single defendant for a single death. This directly affects families seeking compensation after a death caused by another's negligence or wrongdoing.
