Cases may arise when a couple die together (e.g., in an accident) and both have different wills and/or different beneficiaries to their estate but the majority of the estate is joint. The answer has  been decided by the High Court; the Court has upheld the presumption that the oldest person has died before the  youngest person (when the actual timing of death is uncertain). Section 184 of the Law of Property Act 1925 creates a presumption that the oldest person died first in cases where the order of death is uncertain
