Common Legal Issues in Property Development

Can I use an option agreement to secure a site?

Yes, we can help draft and negotiate option deeds that give you flexibility to secure and conduct due diligence on a site before committing to purchase.

What are the legal risks in off-the-plan sales?

There are countless risks - disclosure, sunset dates, and contract variations must be carefully managed to avoid disputes or buyers rescinding contracts.
