5 C.F.R. § 890.804 Coverage.
Title 5 - Administrative Personnel
(a) Type of enrollment. A former spouse who meets the requirements of §890.803 may elect coverage for self alone or for self and family. A family enrollment covers only the former spouse and any unmarried dependent natural or adopted child of both the former spouse and the employee, former employee or employee annuitant, provided such child is not otherwise covered by a health plan under this part. An unmarried dependent child must be under age 22 or incapable of self-support because of a mental or physical disability existing before age 22. No person may be covered by two enrollments. (b) Proof of dependency. (1) A child is considered to be dependent on the former spouse or the employee, former employee, or employee annuitant if he or she is— (i) A legitimate child; (ii) An adopted child; (iii) A recognized natural child who lives with the former spouse or the employee, former employee, or employee annuitant in a regular parent-child relationship. (iv) A recognized natural child for whom a judicial determination of support has been obtained; or (v) A recognized natural child to whose support the former spouse, or the employee, former employee, or employee annuitant makes regular and substantial contributions in accordance with §890.302(b)(2). (c) Exclusions from coverage. Coverage as a family member may be denied— (1) If evidence shows that the former spouse, employee, former employee, or annuitant did not recognize the child as his or her own, despite a willingness to support the child; or (2) If evidence calls the child's paternity or maternity into doubt, despite the former spouse's employee's, former employee's, or employee annuitant's recognition and support of the child. (d) Child incapable of self-support. When a former spouse enrolls for a family enrollment which includes a child who has become 22 years of age and is incapable of self-support, the employing office shall determine such child's eligibility in accordance with §890.302(d), (e), and (f). (e) Meaning of unmarried child. A child, under age 22 or incapable of self-support, who has never married or whose marriage has been annulled, or a child who is divorced or widowed is considered to be unmarried.
