In 1964 Singer married Vickie Lemon, who shared his religious views. They quickly began a family which grew to seven children. Singer raised his family in Marion, Utah, on a 2.5-acre farm, much like a nineteenth-century homestead. Religion was important to Singer and his family. He entered into a plural marriage in 1978 with Shirley Black, an already married woman with four children.

Singer's stand against the public school system began a road of court battles. His dissatisfaction with the school system escalated over a picture in a textbook showing whites and blacks together. He confronted the school superintendent and objected that his children were being subjected to what he considered immoral secular influences. His legal confrontations began when he declared that he would withdraw his children from public school because the Constitution states that states cannot interfere with religious beliefs. The state countered by showing him a copy of the State Compulsory Attendance Law, which states that parents with children ages 6 to 18 must send them to school.
