To be absolutely honest, I admit one thing; the treasury's potential collection wasn't absent... I would recommend that organisations willing to enter the marriage's celebration business be licensed and to cover the cost of assessing their abilities, they would have to pay for the licence annually and a tax on marriages they celebrate to cover the cost of the registration. Of course no discrimination would be admissible on who can be licensed to open a Marriage Celebration Business or the type of marriages they celebrate.
The state and legislation only registering marriage contracts.
