I have represented clients in many estate matters in NH and MA.
Some of these cases involved an heir exerting undue influence on an elderly testator, resulting in her or him leaving a will grossly favoring that heir. Others involved the executor nominated in the will betraying his trust, violating his fiduciary duty, and trying to loot the estate.
These are very difficult cases, because they are often immersed with emotional and psychological issues such as “mother loved you best,” “I loved mother best,” and, “if only you had taken better care of mother, she’d be here today.”
Difficult cases for all involved, but, if there are sufficient assets in dispute, worth pursuing.
