The Royal Institution of Chartered Surveyors (Rics) has mounted a legal challenge against the government intended to suspend the introduction of Home Information Packs (Hips).
The judicial review will examine whether the Department for Communities and Local Government (DCLG) conducted proper consultation before implementing the new legislation.
Home sellers and buyers will be watching closely after recent Rics figures showed homesellers were hurrying to sell their properties before the introduction of Hips on June 1st.
After that date, home sellers will have to bear the cost of compiling a home information pack, estimated at between £400 and £600.
But a question mark now hangs over whether the scheme will go ahead, with a House of Commons vote scheduled for Wednesday on a motion from the Conservative party on whether to scrap Hips.
"Rics has not made the decision to commence Judicial Review proceedings lightly," stressed Teresa Graham, chairman of Rics' regulatory board.
Communities secretary Ruth Kelly said the Rics legal challenge was "groundless".
To oppose the bill was to be "anti-change", "anti-consumer" and "anti-green", she added.
