222.22—Relationship as divorced spouse.
A claimant will be considered to be the divorced spouse of an employee if—
(b)
He or she is not married (if the claimant remarried after the divorce from the employee, the later marriage has been terminated by death, final divorce, or annulment); and
(c)
He or she had been validly married to the employee, as set forth in § 222.11, for a period of 10 years immediately before the date the divorce became final. The claimant meets this requirement even if the claimant and employee were divorced within the ten-year period, provided that the claimant and employee were remarried no later than the calendar year immediately following the year in which the divorce took place.
