Best-selling author Carolyn Jessop will receive support to care for her disabled son for the rest of his life in a settlement reached Tuesday with her former husband, who oversees a polygamous sect's enclave in Texas.

Merril Jessop, 73, agreed to pay $2,350 monthly to his former spiritual wife to support the seven children in her care, with a dollar-for-dollar credit for his Social Security benefit that is currently diverted to her.

They had eight children together before Carolyn Jessop left the Fundamentalist Church of Jesus Christ of Latter Day Saints in April 2003. Their oldest daughter Betty, now 20, returned to the sect after graduating from high school and lives in Texas with her father, who is the bishop at the Yearning for Zion Ranch in Eldorado.

The rest remain with Carolyn Jessop, who chronicled her marriage in the 2007 book Escape . They range in age from 22 to 8.

As part of the agreement, Texas attorney Natalie Malonis, who represented Carolyn Jessop, withdrew various exhibits she planned to use during the child support trial.
