Monica, Making a legal partnership is exactly what a civil partnership is
Sorry Atqui I did not make myself clear. I am aware that Civil Partnership is legal. I was trying to make the point that the simplest way to sort this out is to make the civil partnership, the only legal way of registering a partnership, ie, meld civil registration of marriage and CP into one. All couples wishing to enter a partnership and have the rights and obligations this bestows in law, must go to a Registery Office and register it, no ceremony, just forms filled in and signed.
Any further celebration or ceremony of commitment by the partnership, whether religious, or in any other way, is then entirely up to the registered couple.
It would be no different to the way the birth of a child is legally registered and the parents then sometimes choose to have the child baptised, or to have their own naming celebration. It is the same with death. A death is registered and then you dispose of the body with or without a ceremony as you think fit.
Why should partnership registration be any different?
