Online legal services platform Rocket Lawyer has raised another $15 million in new funding from a so-far unnamed “strategic investor”. Rocket Lawyer previously raised $40 million in capital from August Capital, Google Ventures and Investor Growth Capital (IGC). Rocket Lawyer founder Charley Moore claimed earlier this year that the company is growing revenues by $20 million a year.

Last year, rival LegalZoom sued the company over alleged false and misleading advertising, trademark infringement and unfair competition. Rocket Lawyer has since countersued LegalZoom. Rocket Lawyer, which currently provides legal documents to consumers and small businesses, as well as allowing consumers to find and reach lawyers, is believed to be looking to expand beyond just offering documents. The company recently bought legal Q&A site LawPivot.
