# AddDependentRequest

Model ID: `AddDependentRequest`

HC transport shape for creating/updating a FHIR RelatedPerson dependent.

``relationship`` is a free-form string on purpose: the app sends
title-case display labels ("Spouse", "Child", ...) while FHIR stores v3
RoleCode values ("SPS", "CHLD", ...); the service layer
(``Dependent.parse_relationship``) maps both case-insensitively.

Type: `object`
