Predatory marriages seem to be on the increase, as in this desperately sad case, the vulnerable person often has dementia, and would not have capacity to make a Will, yet are able to marry. 

So what is the answer? Should marriage no longer revoke a will? Or should there be more training for registrars who apparently assess capacity before the marriage takes place. Or perhaps a new basis for annulment of the marriage post death in circumstances such as these, where presently it must be bigamy or incest.

An incredibly sad state of affairs and it feels criminal that this individual got away with it because it wasn't considered a 'forced marriage'.
