Why don’t we borrow from real estate and create a marital lease? Instead of wedlock, a “wedlease.”
Here’s how a marital lease could work: Two people commit themselves to marriage for a period of years — one year, five years, 10 years, whatever term suits them. The marital lease could be renewed at the end of the term however many times a couple likes. It could end up lasting a lifetime if the relationship is good and worth continuing. But if the relationship is bad, the couple could go their separate ways at the end of the term. The messiness of divorce is avoided and the end can be as simple as vacating a rental unit.
A wedlease could also imitate a real-estate lease through the use of security deposits. Each spouse could deposit a sum of money with an independent third party to ensure compliance with the wedlease. A further step could be to authorize the third party to arbitrate disputes between the spouses.
