The stay was ordered as settlement talks continue between Mr McNamara and private investors who are pursuing him for €62.5m over unpaid loans to acquire the Irish Glass Bottle site at Ringsend.
Mr McNamara had previously written to the investors asking them to sign a 'non-disclosure' agreement before releasing the asset statement to them.
The move was designed to ensure 'unnecessary' material was not released to the media.
Mr McNamara has since given the statement to the investors but it has not yet been filed in court, Mr Justice Peter Kelly heard.
Gary McCarthy, Counsel for Mr McNamara, told the judge this week his side wanted an extension of time to 13 April before filing the affidavit of means.
His application arose because, while the investors had been given the statement, there were private discussions between the sides relating to resolving most of the issues between them and it had been agreed the affidavit of means be kept in the possession of the two sides, Counsel said.
The judge was told the investors are consenting to Mr McNamara being given to 13 April before lodging the affidavit of means.
In those circumstances, the judge allowed Mr McCarthy's application.
