The Royal Bank of Scotland and Elite Information Systems have come together to create the first partnership between a bank and a software company specialising in the legal sector.
The move allows solicitors to reconcile client and firm accounts directly with the bank.
Elite, which is based in Los Angeles, has more than 20 legal clients in the UK.
The agreement with the bank will result in the company's software being compatible with Roylink - a scheme linking customers' cash management systems and the Royal Bank of Scotland.
The aim is to give solicitors increased efficiency and accuracy and, consequently, to help save costs.
Miller McLean, director of group legal and regulatory affairs at the bank, said: "The Royal Bank already has very close links with the legal profession and our joint initiative with Elite is a good example of our ability to provide our customers with innovative, added-value products and services."
