Long Term Ramifications of Divorce

The New York Times published an article in its Health section regarding how divorce complicates caregiving for parents. The author of the article is a woman whose parents divorce when she was young and then remarried. Now both her parents and their spouses are in the later stages of life and suffering from various ailments requiring nursing care. The divorce caused her to have twice as many obligations as she would otherwise have. There is nothing that can be done legally to address this issue, but perhaps parents should consider it in their post-divorce estate planning.
