Predatory marriage is the practice of marrying an elderly person exclusively for the purpose of gaining access to their estate upon their death.[1] While the requirements for mental capacity to make a valid will are high, in most jurisdictions the requirements for entering into a valid marriage are much lower; even a person suffering dementia may enter into marriage. In many jurisdictions, a marriage arrangement will invalidate any previous will left by the person, resulting in the spouse inheriting the estate.[1]
In the United Kingdom a campaign, Predatory Marriage UK (originally known as Justice for Joan)[2] was started, working to change laws and procedures around marriage to reduce this practice, supported by lawyer Sarah Young[3] of Ridley and Hall.[4][5] The local MP, Fabian Hamilton MP, introduced a bill in Parliament during 2018 entitled the Marriage and Civil Partnership (Consent) Bill,[6] to establish that marriage should no longer always revoke a previous will and have introduced other protections against predatory marriage.[7] The bill was passed but ran out of parliamentary time, but work is continuing.[8][9]
