“Excellent attention to detail and outstanding commercial acumen”

Our practice

Market Street Legal is a boutique corporate and commercial law firm. We have deep experience in private M&A, private equity and venture capital investments and complex commercial transactions – and we are actively involved in philanthropy and social impact investment. We focus on understanding our clients’ key commercial drivers and risk appetite for each transaction, recognising that profit maximisation is not the only goal across the spectrum of investments.

Based in beautiful Fremantle, Western Australia, our small size encourages us to work efficiently and responsively, building close and trusting relationships with our clients nationwide.

Market Street Legal provides excellent value alignment for:

funds and family offices across the full spectrum of their investments, from traditional investments to social impact investments and philanthropic gifting
transactions with deal value under approximately $50 million (although we assist with transactions of all sizes)
founders pursuing an exit or introducing an investor
flexible generalist support tailored to in-house counsel’s needs.

We welcome the opportunity to discuss how we can assist with your legal needs.
