The Huffington Post recently listed the top ten cases which significantly impacted divorce law. These cases cover many areas of divorce law including alimony, pensions, relocation, foreign judgments, palimony and visitation rights for grandparents.
This a national list. In fact, no specific Connecticut cases appear on the list. However, some of these cases resulted in changes in the law here in Connecticut. The most notable being the Troxel decision regarding the inability of third parties to petition for visitation rights over the objection of a parent unless very specific criteria are satisfied.
