When a bridal couple enters the church in the Netherlands (and Belgium, and Luxembourg, and France, and Germany, and Italy, etc.)
they already are husband and wife.
In most European countries the only legal binding wedding is the one before the municipal registrar. The religious wedding has no any relevance for the law. The bride going down to the aisle and 'given away' by the father is really an anglosaxon phenomenon.
Many European ladies even find it insulting because they are adult, independent and well-educated ladies who have made the choice of their heart for their partner. The father has nothing to do in that. They do not need his permission and for sure not to be 'given away'.
But it is romantic and sometimes you see a father 'giving away' his daughter in church in the Netherlands, which is really nonsense because they already are married.
The most used custom is:
the groom arrives with a special car at the bride's parental home
the brides' parents greet the groom and he asks to see their daughter
the bride walks out of her parental home, the whole street gasps an applauds
the bride and groom together go to the municipal hall
they go to the church (if they want a church wedding)
they go to the reception
