The daughter of former billionaire Sean Quinn has told the Commercial Court she signed a Russian employment contract entitling her to large sums of money without being able to read it.

Aoife Quinn said she received €379,000 from the companies. Her husband and brother owned two of the companies but she did not know who owned the third.

Aoife Quinn said she never kept a copy of the employment contract and returned it to the company.

She was the first of a number of Quinns to be cross-examined by lawyers for the Irish Bank Resolution Corporation about disclosure of information about their assets and accounts.

All five adult Quinn children and two of their spouses are to be cross-examined at the Commercial Court.

IBRC has disputed claims by the Quinns they have provided full disclosure of their accounts and assets.

This morning Ms Quinn said she opened four savings accounts in Dubai after legal proceedings were taken to prevent asset-stripping of the Quinn's international property group (IPG).

She said she opened the accounts in either late 2011 or early 2012, after proceedings were initiated in mid-2011 by IBRC alleging steps were being taken to put IPG assets out of its reach.

Ms Quinn said she has no documents related to those savings accounts as she had provided the relevant bank statements to her previous lawyers, Eversheds, on foot of court orders requiring disclosure of her accounts and assets.

That firm was exercising a claim or lien over those and other documents, she said.

She also said she has no documents about accounts held by her with Ocean Bank in Moscow but had disclosed text messages received by her from that bank concerning the accounts.

Ms Quinn said she had signed employment contracts entitling her to large sums of money but had not read the contracts or kept copies because they were in Russian.

When asked by Mr Justice Peter Kelly how she even knew what she was signing, she said she had been told they were employment contracts by her brother, Seán.

"Maybe I'm unusual but I never kept copies of employment contracts," she said.

Paul Gallagher, senior counsel for the bank, put it to her that if she could not read the contract she would not know what her obligations were under the contract.

She replied: "OK".

Ms Quinn said she has disclosed all documents in her possession and had also disclosed any other documents received by her from other parties as part of efforts to help her brother purge his contempt of court orders restraining asset-stripping.

The cross-examination of the Quinns arises from orders freezing their accounts, which were made last July.

Ms Quinn said she does not have any documents relating to the Quinn's International Property Group assets.

She also said she had never deleted emails to avoid disclosure.

She said she had a policy of deleting emails after a period of time but would keep copies of any important documents.

However, she would not disclose documents if she knew they had already been included in disclosure made by some of her siblings.

IBRC is trying to uncover documents relating to control of companies in the Quinn's IPG, assets, bank accounts and documents relating to salaries from Russian IPG companies in 2011 and 2012.
