Personal injury lawyers in the West Midlands have warned that plans to have higher compensation claims settled in the small claims court could result in fewer people making claims.
The Government is expected to respond shortly to recommendations by a Department of Constitutional Affairs select committee to raise the value of claims made in the small claims court from £1,000 to £2,500.
The region's Association of Personal Injury Lawyers said if the recommendations were implemented the public could lose out.
The select committee's recommendations were made following a 2004 report by the Better Regulation Task Force aimed at tackling compensation culture.
At present, personal injury claimants can generally recover money spent on legal costs as part of a no win, no fee deal offered by many personal injury specialists.
But costs stemming from legal advice or representation in small claims courts action has to come out of the claim-ant's pocket.
An APIL spokesman said: "We know that the lack of legal advice in the small claims court acts as a disincentive for those with low value cases seeking compensation which is rightfully theirs, and that a large proportion would not bring a legal case without a solicitor."
Scottish research had also found that the aid which a district judge provided litigants in the small claims court was limited, he added.
"The aforementioned research from Scotland has found that the people leading the hearing, the sheriffs in Scottish cases, were more reluctant to take an interventionist role where one party was legally represented, as it usually was in personal injury actions.
"In most instances it is the defendant who is represented by either counsel or a solicitor. It is obvious that the claimant, the only one who does not have legal knowledge, is placed in a disadvantageous position.
"The level of proactivity by the presiding judge is further reduced by the high volume of cases which he will hear. As one district judge commented: 'I have a feeling that I am doing less than a perfect job - and it's way less than that on occasions'."
A spokesman for the Department of Constitutional Affairs said the Government had concerns about the potential lack of legal representation in personal injury claims.
"We are carrying out research that the Better Regulation Task Force has recommended. There are concerns about the potential lack of legal representation and that is one of the issues being researched," said the spokesman.
