In Maryland, there is no specification under the law about which parent must provide health insurance.
With that said, if both parents have health insurance coverage available to the child, the following may be considered:
How much it costs each parent under their health insurance plan to cover the child;
Which health insurance plan provides better coverage for the child;
If the child has any specific medical needs which one health insurance plan might be able to address; and
Any other specific details of each parent’s health insurance plan which could affect the child’s health insurance coverage.
