According to Rule 124 of the Constitution, a member whose subscription remains unpaid for one full year shall cease to be a member of all Lodges, provided a notice has been served regarding the arrears. Moreover, a member can only become a member again by regular proposition and ballot, and payment of the arrears of all Lodges will be a condition prior to election.
Therefore, if a Mason is a member of multiple Lodges, he is liable for dues to each of those Lodges, and failure to pay can result in cessation of membership from all Lodges.
