The probate battle between tycoon Nina Wang Kung Yu-sum and her father-in-law was adjourned for half a day yesterday after the 89-year-old said he was too tired to continue. After the morning session, Wang Din-shin, who had been testifying for the sixth day, asked Mr Justice David Yam Yee-kwan to excuse him from the witness stand because he was exhausted. The judge told Mr Wang to rest so he could continue his testimony this morning. Earlier, when cross-examined by barrister Martin Lee Chu-ming, SC, Mr Wang said he left Shanghai for Hong Kong in 1948 and had not returned to the mainland as all his property had been confiscated by the Communists. His wife, Ruen Yu-chin, and three of his children, including Ms Wang's husband, Teddy Wang Teh-huei, flew in later. Asked whether many businessmen stayed behind after the Communist Party took control of China, he said he could not speak for others and asked Mr Lee to remain focused and not talk about politics. The probate tug-of-war between Mr Wang and Chinachem Group chairwoman Nina Wang focuses on whether a 1968 will left by Teddy Wang that names his father as sole beneficiary is valid. Teddy Wang was kidnapped in 1990 and has not been seen or heard from since. He was declared legally dead in 1999. Ms Wang claims he made her beneficiary and administrator in a will dated March 12, 1990. Barrister Edward Chan King-sang, SC, for Mr Wang, said the court would hear evidence from a witness, Donald Cheung, via video link from Exchange Square next Wednesday. Mr Cheung, a former partner in the law firm of Zimmern & Co, was said to have prepared the 1968 will under Teddy Wang's instructions. It is believed that Ms Wang, property tycoon Cecil Chao Sze-tsung, casino tycoon Stanley Ho Hung-sun, former HSBC chairman Sir Michael Sandberg and Sino Land chairman Robert Ng Chee-siong will also be called to testify in the hearing, which continues today. Both parties yesterday agreed to share costs of a real-time computerised translation system being used in the hearing.
