Child support falls under the responsibility of the Child Support Enforcement Department which can assist in determining paternity. By New Mexico law, if a man accepts paternity on the birth of the child, he had only sixty days to revoke this claim before it becomes a finding of paternity. The fees for child support services for families not on public support are higher than other states, with a $60 fee to locate an absent parent, $250 to establish paternity and $150 to take enforcement action against the delinquent parent. Tax interception will cost $25. Other fees will be assessed for testing, the use of an expert witness and filing fees.
