Mr. Hunt (plaintiff) and Mrs. Hunt’s (defendant) marriage dissolved in April 2000. The Hunts had a son and a daughter. Mr. Hunt was ordered to pay $392 per month in child support according to the dissolution order. In July 2002, the Hunts’ son passed away at only nine years old. Following their son’s death, the Hunts reached an oral agreement for Mr. Hunt to pay only $200 in child support per month. However, Mr. Hunt never sought an order of the court modifying the dissolution judgment. Accordingly, the child-support obligation of $392 per month remained in effect. Time passed, and the Hunts’ daughter reached the age of 18 and became a legal adult. Mrs. Hunt filed an arrearage claim, which is a type of claim in which a party seeks unpaid or past-due debt. Mr. Hunt sought relief from the arrearage claim, and the trial court denied his request. Mr. Hunt filed an appeal pro se, or without counsel.
