Does sponsoring a spouse require me to meet a minimum income?

For most spouse and partner sponsorships there is no Low Income Cut-Off (LICO) income test, which is a key difference from sponsoring parents and grandparents.

You still sign an undertaking promising to financially support your partner, and you must not be in certain disqualifying situations (such as being bankrupt, in default on a previous undertaking, or receiving social assistance for reasons other than disability). But you are not required to prove a specific income level simply to sponsor a partner.
