The current laws financially penalise couples and take the focus off what a marriage is. If it works in Scotland it can surely work here.
Couples should have the right to have their wedding in their home or parents home, as in Scotland. A registrar is currently only allowed to marry a couple in a registered venue, including a register office. This adds unnecessary expense, and encourages couples to add even more expenses, with the idea that a wedding day should be some sort of elaborate theatrical spectical, rather than a life long commitment.
