Suggestions to curb property speculation are not legally binding and flat buyers may not heed them, Law Society deputy president Vincent Liang Wan-sang said yesterday. The Government asked the Law Society last week to consider amending clauses in transaction contracts for non-consent flats, to stop people selling before occupation permits are issued. Flats sold under the non-consent scheme are built on land acquired through redevelopment, rather than through public auction. But Mr Liang said there were flaws in the suggestion. Provisional contracts, arranged by property agents and signed between buyers and vendors, did not involve solicitors although they were legally binding, he said. 'Moreover, the buyers who are represented by their own solicitors can choose not to follow the prohibiting clauses and demand to have them deleted from the contracts,' he said. Half the buyers of uncompleted flats built under the non-consent scheme were represented by their solicitors, rather than those of the developers. Mr Liang, a member of the property committee studying the suggestion, suggested consulting property developers on the issue. He denied they would be biased. 'If the buyers cannot resell the flats before completion, the demand may increase for flats sold in later batches,' he said.
