Ok first question:

Is Emancipation to be considered a qualifying event as loss of depedent status?

If so what documentation should be requested to support proof of emancipation?

If I'm not mistaken, a minor must get a court declaration of emancipation from their parents. Think of it like a divorce. You would ask for the divorce decree and support order. In this case, you should at least be able to get the decree of emancipation from the minor. At that point, I would run it by a family law attorney (you are in Louisiana?) and get their opinion on whether they should be offered COBRA.

I’m not so sure that emancipation in and of itself would result in loss of medical coverage. Some dependents become emancipated strictly to get more college grant money. If the medical plan covers students to age 23 how would it know that a dependent became emancipated? All most plans want to know is if the dependent is a full time student. I’ve never heard of emancipation being an issue. That’s not to say it isn’t.
