A client is looking to prepare their Will, they are suffering from a terminal illness but at this stage do not have a clear idea of their prognosis/life expectancy. The client is due to inherit a significant sum from another estate, the estate of X who died recently and is in the early stages of estate administration.The client wishes to accept the inheritance but in their Will they want to say that anything that remains of what they have inherited at the date of death from X’s estate should pass to Y, whereas anything else that was in their own estate should pass to Z. A deed of variation in X’s estate has been discussed but the client does not want to do this, at this stage. In terms of drafting, has anyone come across anything like this/or drafted a clause that way? If so, please could you suggest appropriate wording or ref to a precedent source. Would it not be too uncertain and instead be more advisable for the client to divide the whole of their estate between Y and Z in whatever proportions they deem fit? I would appreciate your views.
