What Our Clients Say About Aptum

“As strangers to the Australian legal system, and indeed litigation funding, we probably weren’t the easiest guys to deal with. But Aptum made the process clear and there were no surprises.”

- Martin Fine (Director)

Case Study

Contesting a business valuation

An investor in an early-stage business had been forced out through a compulsory share buyout in what presented as an undervalued share price, and came to Aptum to initiate a substantial professional negligence claim against the large accounting firm who had conducted the business valuation.

Aptum reopened the valuation to provide our client with a voice in the process, ensuring a fair amount was received based on their interest in the business.

Aptum also worked closely with a litigation funder to provide certainty in pricing to our client, and achieved the outcome within 12 months of issuing proceedings.
