MO SB410

Criminal nonsupport becomes a Class E felony (instead of Class A misdemeanor) when arrearages exceed 24 monthly payments, increased from the previous 12-month threshold

First-time offenders may petition for expungement after 8 years if they have completed their sentence, remained current on all child support with no payment lapses, paid off all arrearages, and have no pending criminal or administrative child support actions

Periodic payments toward arrearages combined with current support payments shall not exceed 50% of the defendant's adjusted gross income after deductions for payroll taxes, medical insurance covering dependents, and other court-ordered support

Adds formal definition of "arrearage" to include unpaid child support and spousal support when the spousal support order also requires child support and the recipient is the custodial parent

Expunged records become confidential and accessible only to parties or by court order; expungement restores the person to pre-arrest status with no legal obligation to disclose the offense
