A family feud over an allegedly forged will involving more than $100 million in property and jewellery is set to end up in the High Court.
Mr Harmesh Singh, 48, is accusing his elder brother, Mr Phagwan Singh, 60, and sister, Ms Dhanwant Kaur, 49, of tampering with their late mother's will.
The defendants deny the allegation and are in the process of obtaining an expert to attest to the will's authenticity.
The case will be heard before the end of the year.
In his writ of summons, Mr Harmesh, a businessman, stated that his father, Mr Ram Singh, died in 2003 at the age of 75.
The patriarch left his entire estate to his wife, Madam R.S. Gurbachan Kaur.
She died in 2009, aged 74, leaving five sons and two daughters.
In her 2007 will, prepared by lawyer Daljit Sidhu, she left 30 per cent of her estate to Mr Phagwan, 25 per cent each to Ms Dhanwant and the other daughter, and 5 per cent each to the remaining four sons.
Mr Phagwan, a businessman, and Ms Dhanwant, a secretary, were appointed executors of the mother's estate.
Court papers filed by Mr Harmesh note that the will was said to have been retrieved from a safety deposit box at Certis Cisco in Singapore held under the joint names of his mother and Ms Dhanwant.
Mr Harmesh had the will studied in September last year by forensic handwriting expert William Pang, who noted irregularities.
One irregularity he found was that only one page of the three-page document was numbered, and wrongly, too - the third page had been numbered as page two.
He also found "highly visible irregularities" between the pages, including inconsistencies between the margins of the pages.
Further, he observed that one of the mother's signatures on the will was "questionable".
Mr Harmesh said he had not been offered an explanation for the inconsistencies, despite repeated requests.
In addition, he accused Mr Phagwan and Ms Dhanwant of having breached their duties as executors of the will by failing to declare their late mother's assets.
