A new law in Maryland allows consenting couples with no minor children to file for divorce without having to wait one year. The change will go into effect on Thursday, while it eliminates the waiting period for those couples, couples with children will still have to live apart for a year before they can file. The legislation was proposed by Senator Robert A. Zirkin. The current law starts the one-year clock on the day one spouse moves out of the common home. If the two later stay under the same roof for even a night, the clock resets to Day One.
