I had a sister 'drop out' for about 10 years after my father died, but we have made amends and have a great relationship now.

My other sister 'dropped out' when her husband and I could no longer be partners in business. (he stopped showing up for work, disappeared for many hours a a time, daily.) Rather than try to work out an amicable division, he lawyer-ed up and cost us a fortune.
