Child support in Mississippi is typically calculated using a guideline worksheet that considers both parents’ gross incomes, the number of children, and custodial time. The worksheet adjusts for allowable deductions and may account for shared expenses such as childcare and insurance premiums. Judges use this baseline while retaining discretion to deviate when statutory factors make the guideline amount unjust. Accurate income documentation, such as pay stubs and tax returns, is essential to produce a reliable calculation and ensure the order reflects each party’s financial reality. Because courts also consider special circumstances, additional expenses like extraordinary medical costs or educational needs may alter the final order. The process involves filing required financial disclosures and presenting evidence to support income and expense claims. Parties can reach an agreed order by negotiation or mediation, or the court will set support after a hearing. Understanding the worksheet and preparing documentation in advance helps streamline resolution and avoid disputes about the underlying numbers.
