The new Legal Indemnities Online website includes block policy transactions and easy premium payment tracking and processing, all through a simplified online accounts system.
This means that businesses can pay for policies on an individual basis, or as a single payment at the end of the month.
There are 35 core covers available online, including breach of restrictive covenants, lost title deeds and leasehold problems, with around 170 different variations depending on risk type. Quotes can be received instantly and policy documents can be viewed, saved or printed in minutes.
Aviva has also launched its own self-issue packs for solicitors, which will offer immediate cover for the most common residential risks.
Nina Woodwiss, legal indemnities trading manager, said: "L.I.ON is already used by thousands of solicitors and conveyancing companies in England, Wales and Northern Ireland to arrange indemnity cover mainly for residential property transactions for a wide range of situations. There are also covers available for a smaller selection of commercial transactions.
"The changes to L.I.ON will further help solicitors to ensure their clients meet the latest insurance regulations, and we will continue to make improvements to the site throughout the year.
"If a particular cover appears not to be available on L.I.ON, users can submit a request to Aviva's experienced team of underwriters for consideration. All L.I.ON users are given priority service for any enquiries to the legal indemnity team."
