The Moneyologist: Can I sue my mother for changing my last name?

Dear Moneyologist,

My family has been fragmented for at least the last three generations, creating an elaborate blend of step-everything and relationships that were seldom defined by blood. My deceased grandfather — whom I loved dearly — is not my relative by blood, nor is the so-called father whose name I carry. Suffice it to say our family traditions are fragmented or non-existent.

When my mother divorced and remarried, she and my step-father changed my name and my younger brother’s to match his, creating this collection of five kids where the oldest two had one last name and the younger three had another (my parents had the youngest son together).
