Stepmothers are present in many of the battles launched over estate battles, according to Forbes in "Stepmothers: The Cause Of So Many Estate Fights."
The real problem is not really stepmothers. When family members do not get along for other reasons, they often find themselves at odds over the estate of a deceased loved one. It just so happens that one of the primary familial relationships gone awry is that of stepmothers and their stepchildren.
What this means is that people who have entered a new marriage with children from a previous relationship, need to understand the family dynamic and how it could have an impact on the administration of their estates.
An estate planning attorney can advise you in creating an estate plan that fits your unique circumstances, including a blended family.
