My sister is co-executor of my mother's estate. The will stipulates the estate is to be divided equally between her seven children. My sister is refusing to put the will in probate for "emotional reasons". In the meantime, she took my mother's car to her home (out of state) for her personal use, she is refusing to allow us to put my mother's home on the market, and she is having workmen come in and make repairs and changes to the house and writing checks from the estate to pay for them. How can I have her removed as executor so our family can proceed with probate of the will, sale of the house and distribution of assets? State is New Jersey.
