My sister who lives abroad is selling her property in Bulacan. The TCT title is registered under her name "married to" husband who is not a Philippines citizen. She is too busy to travel to the Philippines and handle the sale of the property (empty lot) and just wants to execute a special power of attorney to assign me all the rights to sell the land on her behalf. How would a SPA work in this case since she is married to a non Filipino citizen? Would a normal SPA work since foreigners cannot own land in the Philippines?
