A consultation has been launched into whether conveyancers should be made to publish their fees.
They could also have to publish data on complaints.
The consultation, launched by the Solicitors Regulation Authority, is aimed at helping consumers to shop around and make informed choices when choosing law firms.
The SRA proposals including a register of law firms, where some would publish information on prices and the services included.
It is suggested that firms would only do this for certain types of work, such as personal injury, wills and conveyancing.
The SRA is also considering publishing data on the complaints that firms receive.
The move comes after the Competition and Markets Authority said the legal services market is not working well for the public or small businesses.
The CMA recommended that better information be made available to create a more competitive market, where people can make more informed choices.
The consultation, at www.sra.org.uk/consultations, is open until December 20.
