In Ireland up until the 1920s, couples could legally get married just by walking towards each other as LONG as they did so in Teltown, county Meath and ONLY on Saint Bridget’s Day.
If the marriage failed, they could also divorce at the same spot they got married, and even on the same day of marriage! And by doing so, all they had to do was walk away – literally.
The custom was based on old Irish Brehon laws which allowed for temporary marriages to happen.
It’s a little more complicated these days and not as easy!
