MMC Benefits Handbook
Spouses and Domestic Partners
For your spouse and domestic partner to be eligible for coverage under the plans that provide coverage options:
  • you must meet the employee eligibility requirements for the plan,
  • the family members you want to cover must meet the eligibility requirements for the plan, and
  • the insurance benefit plan must provide coverage for the eligible family member you wish to cover.
Spouse / Domestic Partner
  • You have already received a marriage license from a US state or local authority, or registered your domestic partnership with a US state or local authority.
Spouse Only
  • Although not registered with a US state or local authority, your relationship constitutes a marriage under US state or local law (e.g. common law marriage or a marriage outside the US that is honored under US state or local law).
Domestic Partner Only
  • Although not registered with a US state or local authority, your relationship constitutes an eligible domestic partnership. To establish that your relationship constitutes an eligible domestic partnership you and your domestic partner must:
    • be at least 18 years old
    • not be legally married, under federal law, to each other or anyone else or part of another domestic partnership during the previous 12 months
    • currently be in an exclusive, committed relationship with each other that has existed for at least 12 months and is intended to be permanent
    • currently reside together, and have resided together for at least the previous 12 months, and intend to do so permanently
    • have agreed to share responsibility for each other's common welfare and basic financial obligations
    • not be related by blood to a degree of closeness that would prohibit marriage under applicable state law.
Marsh McLennan reserves the right to require documentary proof of your domestic partnership at any time, for the purpose of determining benefits eligibility. If requested, you must provide documents verifying either the registration of your domestic partnership with a state or local authority or your cohabitation and/or mutual commitment.
My spouse or domestic partner also works for the Company; can I still cover my spouse or domestic partner under the Plan?
If both you and your spouse or domestic partner are employees of the Company, you may elect to cover each other.
