Tennessee child support authorities can suspend driver’s licenses and take other actions to ensure the timely payment of child support. The non-custodial parent’s income and number of children that require support determine child support. One child would receive 21% of the net income, 33% for two, up to 46% for four children. Payments are garnished automatically from the non-custodial parent’s paychecks. Medical insurance is mandatory for all children in Tennessee. If the parents cannot come to a visitation agreement, then the court will determine a visitation plan that involves visits every other weekend, 4 to 6 weeks in the summer and rotating holidays. Child support terminates at the age of 18 or graduation from high school. If you need legal advice and assistance, contact Tennessee lawyers.
