I recently purchased a home at 75% completion where I signed all agreements by 7th of March. One week prior to the developer progress payment claim (dateline is 13th April), my bank told me they have yet to approve payment due to incomplete Power of Attorney documents. The development project is a JV between the developer and 8 individual landowners. Now the developer threatens to charge interest on me for failure to obtain payment from my bank. Since I assume it is in the developer's interest to earn an extra buck, is there any legal route I can resort to to deter them?
