Can I authorize a representative to sign the Contract to Sell (CTS) on my behalf? What are the requirements?

Yes. Should the buyer wish to authorize a representative to sign the Contract to Sell on his/her behalf, the authorized representative should present and submit an original copy of a duly notarized (or consularized, if executed outside the Philippines) Special Power of Attorney (SPA), together with the buyer/s’ valid government-issued ID as well as his/her own for validation.
