My Grandfather, a resident of Lehigh County, Pennsylvania, died of dementia 12 years ago. Shortly before his death, his will was changed giving everything to my Aunt. We believed that my grandfather died broke, but now that my Aunt died we found out that he had a joint account with her containing a large sum of money. The prior will stated that I would receive one-fourth of his estate. Can I challenge the will?
First, a challenge case alone based on incapacity or undue influence, even if successful, would not help you. You stated that the funds were in a joint account. A joint account passes outside of probate, meaning the Will has no effect on the joint ownership.
