Marriage Laws for Italy Weddings

There are four sets of marriage laws for weddings in Italy:

Marriage laws of your country of origin. These describe what must be done to gain approval from your home country to get married in Italy. We have these spelled out in our wedding regulations page for the most popular countries we deal with. Other nationals must talk to their embassy or consulate in Italy to get these marriage laws defined.
National marriage laws of Italy. These are laws that apply to all marriages. The main law to note is that each one of the couple must obtain a Nulla Osta ( a certificate that says there is no impediment to the individual being married). Again this is described in our wedding regulations page.
Local marriage laws. Each town hall sets their own regulations. For example, most mayors will insist that the wedding only takes place in the town hall (as decreed by national laws); however, some (e.g., some of the mayors that we deal with) will allow the recitation of the legal part of the marriage ceremony and the paperwork signing to be done informally in the town hall with just the bride & groom present. This is followed by a full wedding ceremony at any other venue with all guests, but with most of legal jargon stripped out. Some mayors will insist in a minimum stay for the couple prior to the marriage in Italy.
Religious Marriage Laws /Regulations for Religious Weddings in Italy - These vary widely. See "Catholic Marriage Laws", Non-Catholic Marriage Laws.
