This Plan will be secondary. • For adopted children, children placed with you for adoption, or foster children to be considered eligible dependents, you must provide the Fund Office with appropriate legal documentation, satisfactory to the Plan in its sole discretion, such as adoption papers or a court order appointing you as the legal guardian for the child. • For a stepchild to be considered an eligible dependent, the Fund requires that the employee provide a copy of the child’s birth certi ficate and proof of the employee’s marriage to the child’s biological or adoptive parent. The Fund may also require any and all documentation, including paternity papers, court order, state order and/or divorce decree setting forth the relationship with th e child. • If a dependent Spouse is eligible for benefits under this Plan as an active participant, benefits will be payable for the Spouse first as a participant, then as a dependent. In no event will benefits exceed 100% of covered Charges incurred. • If a d ependent child loses eligibility status, the child may regain eligibility only by satisfying all of the requirements included in the Plan’s definition of an eligible dependent and these dependent Eligibility Requirements.
