Dear Eric: My brother passed in 2023. He was not married and had no children. He left an estate of $1.5 million. My two sisters and I split his estate equally and have finally closed the estate. From the start, my older sister’s husband protested that we should not split the estate equally. He says we should have split it to “level the retirement playing field.” In other words, I should have declined my inheritance to give my sisters a retirement financially equivalent to what my husband and I have.
