haha, i have the same question also. ".....beginning from the date of this letter and ending on the date of the Agreement" means from now till the day u sign the SPA? No LAD in this period, right?

I am assuming "the Agreement" referring to the SPA. Correct arr? Anyway, when letter is read in full content, it could mean otherwise.

Anw, agree with Kochin, developer can ask u to sign letter to waive ur right for LAD claims in this manner, but that doesnt stop purchaser from claiming their LAD in Tribunal.
