The High Court will be providing judgment in a £300,000 inheritance dispute between step siblings, over which parent died first. John and Ann Scarle , who each had children from previous marriages , were both found dead from hypothermia after police were called by their neighbours to their home in October 2016.

The “Commorientes Rule” means that in a case of apparently 'simultaneous' deaths, if two or more people die in circumstances where it is not possible to determine who died first, the younger is deemed to survive the elder - Section 184 of the Law of Property Act 1925 . 

Following this rule, Mr Scarle (79) will be presumed to have died before his wife (69) unless compelling evidence to the contrary is provided. Depending on the answer the Court gives, the step children on one side of the family stand to inherit everything, whereas the other side will inherit nothing. 

Judgement has been reserved for a later date. 

The High Court dealt with the Commorientes Rule rule in Jump & Jones v Lister [2016] EWHC 2160 , where the couple had drafted mutual wills, giving their estate to each other. Interestingly, in that case the survivorship clause was not invoked between the couple because the husband had not survived his wife for the '28 days' stipulated in the will.
