Trump's lawyers said that she ought to be exempt from deposition of her "special circumstances".
"Accordingly, she can not avoid a deposition in this matter".
Her manufacturer has flatly rejected the charge.
"Testimony of Mrs. trump would be an unnecessary distraction and would interfere with the performance of her duties in the White house", said lawyer Darren Sanders.
Ms Trump stepped down from her corporate position before her father took office and her legal team said she should not be deposed because she "does not possess any unique information" about her company's shoe designs. Trump can only be questioned for two hours and that it must occur on her turf in Washington DC. "A deposition is appropriate".
Last week, Trump's lawyers requested that U.S. District Judge Katherine Forrest block her from submitting to a deposition on the basis that she "had no involvement in the designing process", the Daily News reports.
Aquazzura is seeking unspecified damages.
The judge's ruling said: "While that declaration does assert a lack of personal knowledge of the design at issue, plaintiff asserts otherwise". The judge said the deposition should occur by the end of October on a mutually acceptable schedule.
Aquazzura, in its lawsuit, said its shoe designs have "skyrocketed to fame in the fashion world" since the company was formed in 2011, with its shoes "coveted by fashionistas and celebrities alike".
Aquazzura say Trump's shoe copied "nearly every detail of the "Wild Thing" from the shape and silhouette to the fringe covering the toes, to the tassel on the heel".
The Aquazzura "Wild Thing" shoe was ripped off by Ivanka's "Hettie" model, according to the lawsuit, and according to photos like the above one from Twitter users claiming that Ivanka will likely lose this lawsuit.
