Support is the non-resident parent’s money duty — custody defeat does not zero it, and there is no national percentage table.
Parents must support minor children (and adult children who cannot live independently in statutory cases). After divorce, the parent who does not have direct custody usually pays support. Amounts follow the child’s needs, local living costs and the payer’s means — courts use evidence, not a single national formula. Agreements can set a figure; courts can still adjust if it undercuts the child. Enforcement is a civil-judgment problem if unpaid. This is not the custody page and not the city ‘dilemma’ blogs.
