"Pagan" is a word with extremely broad connotations and encompasses a huge number of otherwise-unrelated religious practices. Depending on the tradition, she might. Some traditions, such as Dianic Wicca, are very feminist in their orientation and may frown on such a practice. The "pagan" ritual of handfasting (marraige) is merely a promise that for a year, you will remain faithfully to that person's wife/husband. Every year and 1 day, the handfasting is either renewed or not. Pagans do not require a woman to legally adopt her husband's name after the ritual. She may choose to, she (or they both) may choose to hyphenate their names or adopt a new one together. Or she may continue using her maiden or legally chosen name. There are no hard and fast rules.As for the Ritual of handfasting... It is performed before a High Priestess &/or High Priest who may or may not be empowered by the "State" to perform "legal" marriages. A handfasting may as stated above be for the "year & a day" (this is a Pagan deffinision of a year the "day" in question is Samhain - believed to be a day outside of time. It does not mean your anniversary progressively gets a day later per year) OR for "as long as the love shall last". Both Rituals may be disolved at the end of the term. A Correction to the above A Pagan handfasting is a ceremony which is personal to the two people getting married. As opposed to what is suggested, there are no "rules" regarding who performs it, or the length of time for which the vows are made. The celebrant may be a "High Priest / Priestess", or it may be a friend, or family member of those getting handfasted, or the couple may choose to act as their own celebrants. The comment about being empowered by the state is relevant only to the USA. In many other countries a Pagan handfasting can not be a legal marriage (a source of much annoyance to Pagans who have to go through two ceremonies!). The length may be "for a year and a day", it may be "for as long as love will last", it may be "for this life", it may be for whatever length of time the couple decide is appropriate.
