<p>According to what I have read, the adult child can be married and stay on the parent insurance (if they are otherwise allowed to stay on the plan). Their spouse and/or child would not be eligible to be on the plan. </p>
<p>My daughter is getting married next year. The current plan is that her fiancee stays on his Mom’s plan and our daughter stays on ours. Really hoping they both find good jobs and are able to get their own pretty soon after. It does cost us extra to have her on ours as my husband and son are not on it so the only reason we have the family plan is the +1. (my Husband is retired and on medicare and the company booted all their over 65 retirees a couple of years back.). Her fiancee is an only child so I am guessing his Mom is in the same situation. If one of them gets a job with good benefits it will hopefully be a better deal for them to get on their own plan. </p>
<p>Not holding my breath on the getting a good job front - never seen 2 such disorganized people when it comes to planning their after undergrad future.</p>
