Public relations boss Sarah Sparks' company has claimed her ex-husband's firm was trying to put "undue pressure and financial hardship" on her.
The Supreme Court earlier this year refused to hear Sparks' appeal against a decision involving St Heliers property she owned with her former husband Greg Olliver.
Sparks runs markomPR and Olliver is a former high-profile developer involved in a range of projects including Ngunguru Spit plans and the development of what is now Todd Property's Stonefields, Mt Wellington.
Companies linked to the pair have been back in the High Court at Auckland this month after a firm he directs, CIT Holdings, demanded $14,486 in court costs from her firm, Glover No.2.
Sparks' company applied to set aside the demand, although it did not dispute it owed CIT that amount.
