The total value of her estate - £1,181,207 - passes to her father Jack as she had not written a will when she was shot dead on the doorstep of her home in Fulham, west London, in April.

But because of her father's age - he is in his eighties - her estate will be administered by her brother Nigel until further representations are granted.

According to solicitor Nicholas Brown, the net value of her estate is £863,756, which takes into account her mortgage and the income tax she paid as a self-employed worker.

Mr Brown, from London-based firm Bircham & Co, said about £276,000 of that sum would be payable to the Inland Revenue in inheritance tax. The majority of it had been paid, he added.

Miss Dando was planning to marry Dr Alan Farthing in September. If she had died after the ceremony, Mr Brown pointed out, the Inland Revenue would have only been entitled to £40,000 in inheritance tax.

Police are still searching for her killer

What happens to the remaining sum - about £600,000 - is up to her father, he added.

"It's entirely in his hands. I don't think anyone has a legal claim against that," he said.

There would also be no tax implications if the money was given to other family members or to Dr Farthing.

The level of tax payable would only be reduced if some of it were to be given to charity.

It is now expected to take at least a year to sort out all Miss Dando's financial dealings, including her income tax and the sale of her house on 15 July.

Mr Brown added that the work had been made more complex as the police had kept all the papers for their continuing inquiries into her killing.

Nigel Dando said in a statement: "I am very grateful to the police, the BBC, and all Jill's professional advisers for providing Bircham & Co with the necessary information so promptly, thus ensuring that the sale of Jill's property could proceed on time."
