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.
