If you remarry on or after your 55th birthday, you can keep your CHAMPVA benefits after you remarry. If you remarry before age 55, your CHAMPVA benefits will end on the date of your remarriage. If you remarry before age 55, but your remarriage ends, you may qualify for CHAMPVA again. The first date that you qualify again is the first day of the month after your remarriage ends.
