Lifestyle Home Nicole Curtis' Ex Ordered to Appear In Court Over Unpaid Child Support The news comes amid an ongoing years-long custody battle between the former couple, who share a three-year-old son By Madison Roberts Published on February 8, 2019 07:05 PM Share Tweet Pin Email Photo: From left: Nicole Curtis, her son Harper and Shane Despite having reached an agreement over custody of their son in October, Nicole Curtis and ex Shane Maguire still have unfinished business. According to court documents first reported by The Blast and obtained by PEOPLE, Maguire, who shares son Harper, 3, with the HGTV star, has been ordered to appear in court over $6,059.50 in unpaid child support. The document was filed on Jan. 16 by the State of Michigan. If he fails to prove why he hasn’t paid, Maguire could be held in contempt of court, and if he does not show up for the proceedings, he could be arrested. Curtis, who is the star of HGTV and DIY Network’s Rehab Addict, declined to comment on the matter and Maguire’s attorney did not immediately respond to PEOPLE’s request for comment. In July, Maguire filed for sole custody of Harper, alleging that Curtis was “not a fit” mother because, he says, she had intentionally inhibited his court-ordered time with their child. Nicole Curtis Says She Will Keep Fighting for Her Family: ‘Sometimes the Storm Clears the Path’ After a contentious, years-long legal battle, in October, Curtis and Maguire reached a settlement that allowed them to maintain joint custody of Harper. Based on the terms of that agreement, neither parent is required to pay child support. However, before the agreement was signed, Curtis, 42, was allegedly receiving $1,200/month in child support from Maguire, according to the Blast. It’s possible the current sum owed stems from that prior agreement.
