Setting Aside Spousal Support Agreement Waivers Tel: 604 602 9000
Section 164 of the Family Law Act sets out what a court should look at in cases where someone seeks spousal support after signing an agreement waiving it on divorce or relationship breakdown. If you are unmarried you need to use the Family Law Act not the Divorce Act if you are Setting Aside Spousal Support Agreement Waivers.

You Don’t Need To Prove A Material Change Since The Agreement Was Signed But It Is A Factor
MacLean Law’s UHNW Do you need to prove a material change to get support after signing a marriage agreement waiving it?
No, you do not need to prove material change in circumstance in order to change the agreement. Whether there has been a material change in circumstance is merely one of several factors listed at s. 164(5) FLA.
The language of s. 164(5) — and, in particular, the use of the phrase “on consideration of the following” before the enumeration of factors — signals that a material change of circumstance is not a necessary element of a finding of significant unfairness. This interpretation is supported by the recent case law: Goldstone at para. 48; Hinz v. Davey, 2022 BCCA 232 at para. 29; Reiner at para. 12; and Deboer v. Deboer, 2017 BCSC 735 at para. 14.
