All spousal support orders continue until they are terminated by the court or modified by a subsequent court order. A spousal support obligation cannot arbitrarily be stopped by the person paying. Any modification or termination must be done through proper legal channels. Failure to do so can incur substantial support arrearages, and the law imposes interest of 10% per annum on any unpaid balance. There can be other serious consequences, which a qualified family law attorney can discuss with you.
