Family cover for expats: adding a partner or children to your policy
How family cover works on an international policy - eligibility, timing, and what changes mid-year actually cost.

International health insurance is structured around a principal insured person, with partners and children added as additional applicants. Here is how that works in practice when your situation changes during the year.
Who can be added?
A partner - married, in a civil partnership, or unmarried in most policies - can be added at any age, subject to the same overall age limit as the principal. Children are typically eligible from birth to age 17, with the option to extend until 24 if they are in full-time education.
Pricing and continuity
Each additional person is priced on their own age band, which means children are usually the cheapest line on the policy. There is no automatic family discount on most international policies, but per-policy admin charges spread across multiple insured people make a family plan meaningfully cheaper than buying separate policies.
Adding people mid-year
You can add a partner or child during the year - at marriage, at the birth of a child, or when an adult child returns home - without resetting the policy. The premium is pro-rated from the date the new person joins, and the rest of the family keeps continuous cover.
A note on maternity
Maternity benefits typically have a 10-12 month waiting period from the policy start date before they pay out. If you are planning a pregnancy, factor that lead time in when you choose a commencement date.
