77. In the event of cessation of the conjugal relationship between a member of the plan and a spouse, within the meaning of subparagraph 2 of the first paragraph of section 71, the member and the spouse may, in the ensuing year, agree in writing to a partition of the benefits accumulated by the member under the plan; such an agreement cannot, however, confer on the spouse more than 50% of the value of the benefits.
For that purpose, the member and the spouse are entitled to obtain the statement described in section 76, established on the date of cessation of their conjugal relationship.
The plan administrator must partition the benefits under the plan to the extent provided for in the agreement referred to in the first paragraph and in the manner prescribed by regulation.
