Never having needed to be consummated, civil partnerships ought not to be confined to unrelated same-sex couples, or even to unrelated couples generally.
Furthermore, any marrying couple should be entitled to register their marriage as bound by the law prior to 1969 with regard to grounds and procedures for divorce, and any religious organisation should be enabled to specify that any marriage which it conducted should be so bound, requiring it to counsel couples accordingly.
There should be similar provision relating to the Methodist and United Reformed Churches, which also exist pursuant to Acts of Parliament, as well as by amendment to the legislation relating to the restoration of the Catholic hierarchy.
Entitlement upon divorce should be fixed by Statute at one per cent of the other party's estate for each year of marriage, up to fifty per cent, with no entitlement for the petitioning party unless the other party’s fault be proved.
That would be a start, anyway.
