2.  Continuation of deferral by spouse.  A spouse who does not meet the age requirements of subsection 1, paragraph A or the disability requirement of section 6251, subsection 1, paragraph A, but is otherwise qualified to continue the property in its tax-deferred status under subsection 1 may continue the deferral of property taxes deferred for previous years by filing a claim within the time and in the manner provided under section 6251. If a spouse eligible for and continuing the deferral of taxes previously deferred under this subsection becomes 65 years of age or meets the disability requirement of section 6251, subsection 1, paragraph A prior to April 1st of any year, the spouse may elect to continue the deferral of previous years' taxes deferred under this subsection and may elect to defer the current assessment year's taxes on the homestead by filing a claim within the time and in the manner provided under section 6251.
