Will support be reduced when my ex retires at age 65?

Experienced Bay Area Family Law clients will tell their clients that retirement constitutes a change in circumstances. 

A supporting spouse's attainment of retirement age typically constitutes a material change of circumstances for purposes of a motion to modify a spousal support order, depending on the circumstances of a given case..

It has been found that there is no material change in circumstances occurred when the obligee became old enough to access a retirement fund without penalty, where the accessibility and possible increase in value of the obligee's share of the retirement accounts were part of the parties' expressed reasonable expectations in entering the stipulated judgment, the retirement accounts were divided equally between obligor and obligee, and by the time of the hearing the obligor was also old enough to access his account without penalty; since the marital settlement agreement, the obligee had become unable to work due to illness, and the obligor's income had increased.
