What Our Clients Say
“I almost lost nearly 400,000 baht in condo down payments. OSP LEGAL helped me get every baht back!
When I received a letter canceling my condo purchase agreement and stating that my nearly 400,000-baht down payment would be forfeited, I was shocked and stressed. The developer claimed I had failed to show up for the transfer, even though I never received any notice of the transfer. It felt like I was about to lose a huge sum for nothing, and I had no idea what to do.
Fortunately, I found OSP LEGAL. The team listened carefully and thoroughly reviewed the purchase agreement and the developer’s mailing records. The turning point came when OSP’s attorneys discovered that the developer had sent the transfer notice to an “alternate address” — not the address specified in the contract, and I had never submitted a written change of address. This meant the notice was invalid under the contract.
OSP LEGAL filed a lawsuit on my behalf, arguing this critical error. The court ruled in my favor and ordered the developer to refund the full 392,800 baht plus interest.
I felt an enormous sense of relief and am deeply grateful to the OSP LEGAL team for catching a small but crucial detail that made all the difference. I highly recommend OSP LEGAL to anyone facing a real estate contract dispute. They are thorough, professional, and they truly deliver results.
