Lord Archer's accountant, Mr Barry Carmel, was questioned yesterday at the Old Bailey about the £500,000 damages the novelist was awarded after his High Court libel action.
Lord Archer said he would give the damages to charity after his 1987 victory against the Daily Star which had accused him of having sex with a prostitute while he was deputy chairman of the Conservative Party.
Lord Archer (61) and his former friend, Mr Ted Francis (67), are accused of dishonesty in relation to diaries and alibis connected to the case.
Mr Roy Amlot QC, for Mr Francis, showed the accountant a piece of paper which Mr Carmel said appeared to be in Lady Archer's writing.
Mr Amlot said: "I suggest to you that out of the full amount, £130,000 was paid to different charities."
Mr Carmel replied: "That is what this piece of paper says."
Earlier, Mr Carmel had been asked by Mr Amlot if he could say what proportion of the damages was paid to charity.
Mr Carmel said: "I know very high amounts were paid to charity. I cannot give precise amounts. Lord Archer would have made his own decisions on how much and to whom it was paid."
Mr Carmel said his company would have advised Lord Archer on tax deductions for more substantial amounts.
Lord Archer denies three counts of perverting justice, two of perjury and using a diary as a false instrument.
Mr Francis, a retired television producer, denies one charge of perverting justice by providing Lord Archer with a false alibi.
Lord Archer arrived at court with his wife and their grown-up sons, William and James. Mr Carmel was released as a witness; a colleague will produce tax documents in court today.
A solicitor, Ms Paula Lent, told the court that she was handed an A4 diary in the presence of her boss, Lord Mishcon, in 1987. She said it was partially obscured by paper and the two halves held open with strong elastic bands.
The prosecution alleges the diary, which was later used in the libel hearing, was a fake.
The hearing will continue today.
