Permanent alimony continues indefinitely. The main bases for teasing payments of permanent alimony are the death of the payor, the death of the recipient, or the remarriage of the recipient. Cohabitation of the recipient with a member of the opposite sex also is a common basis for cessation of permanent alimony. Generally, the cohabitation needs to be of a permanent or near permanent nature, with the parties who are living together sharing living expenses. A few overnight visits usually do not constitute cohabitation for the purpose of stopping alimony payments.
Unless an agreement between the parties says otherwise, payments of permanent alimony can be adjusted upward or downward based on a change of circumstances. If the recipient gains employment at a well-paying job or receives a significant amount of money from an other source, that might be a basis for reducing alimony payments. If the recipient incurs unexpected medical expenses (that are not covered by insurance), that might be a basis for increasing alimony payments, if the spouse paying alimony has the ability to pay more.
