What are the risks in making spousal maintenance non-modifiable?

Both you and your spouse takes a risk in making spousal maintenance non-modifiable. For the recipient spouse, they bear the risk that they may need more money than initially thought or may need it for a longer period of time. The paying spouse bears even more risk. If a paying spouse becomes disabled or loses their job or business, they must still pay their spousal maintenance. There are occasionally some very harsh results that happen to a paying spouse because of a non-modifiable provision.
