More needs to be done to help New Hampshire families collect back child support, according to some parents who have been fighting for years to collect what they’re owed. The Division of Child Support Services helps families establish and enforce support orders, but some cases fall through the cracks. "It's not a case. It's a family," said Alicia Houston, who said she has been fighting for back child support since 2012. "I have two boys, 11 and 7. Jordan and Kobe. They're humans. They're people." Houston calls herself a squeaky wheel as she tries to get help getting what her family is owed. "Fast-forward to now," she said. "It's still $143 a week and $20 a week for arrearages. I don't know if you're really good at math, but now, it's upwards of $5,000." The target of Houston's frustration is not the father of her two sons, but the Division of Child Support Services. "If somebody's not paying child support, what are you doing to enforce it?" Houston said. "Because you're offering a service on your website. You say that you'll help enforce orders. You say that you'll help obtain orders." Kysa Crusco has practiced family law in New Hampshire for more than 15 years. She said she often advises her clients to avoid going through the state to get child support enforcement. "I've seen it take the Division of Child Support seven or eight months to start processing payments," Crusco said. Legal experts said that parents who work outside a corporate structure, such as subcontractors or the self-employed, are the hardest enforcement cases. "If you have someone who doesn't have an employer who gives them a paycheck, then you don't have a way to do a wage assignment," family law attorney Marilyn Mahoney said. DCSS declined multiple requests for an interview but provided some statistics. In New Hampshire, 38,551 families receive child support. DCSS collects and distributes more than $84 million annually in child support. The state reported last year that $225 million is owed to custodial parents in back child support. Mahoney has practiced family law in New Hampshire for decades and said she has complete faith in caseworkers at the division, but she said they are overwhelmed and under-resourced. The state told News 9 that the agency has 84 child support case workers who each carry about 460 cases per year. The division gets most of its funding from the federal government. For every $1 that a state spends on its child support program, the federal government reimburses it 66 cents. But critics said that more than $15 million annually is not enough to effectively enforce child support. Mahoney said she believes New Hampshire is letting children down. "On all fronts, because we're so concerned about not spending any money," she said. News 9 compared New Hampshire child support arrearages to other states with similar populations. New Hampshire averages nearly $8,000 owed per case with arrearages. That's better than Maine, which is at nearly $10,000 per case, but worse than Montana, which reports nearly $4,400 per case. Frustrated parents such as Houston said that at the on-again, off-again rate her ex is paying, it will be 20 years before the back support is paid off, and she wants the state to be more aggressive. "I kept asking them, 'Well, every time you go to court, shouldn't you be asking for the full amount?'" Houston said. "Because that's what's owed to the case. I mean, if it's $18,000, $5,000 -- it doesn't matter if it's a dollar. The full amount owed to the case is what at the end of the day is owed to the children." Some states charge interest on back child support, but interest doesn't accrue in New Hampshire. The statute of limitations for collecting unpaid child support is 20 years. Houston said she believes at the rate her ex is paying, she will never see the full support she said her sons deserve.
