Many clients we represent on both sides of the spousal support equation would like to know how long they will potentially have to pay or for how long they will receive maintenance. This is a complicated question that really has to do with how your case is resolved. In Missouri, if your case proceeds to trial and the Judge orders maintenance, that maintenance order is almost always going to be ordered as modifiable maintenance. If your case settles prior to trial, then the parties can agree to modifiable maintenance or non-modifiable maintenance.
