BALLATAN V. CA
304 SCRA 34
Petitioner constructed a house and found out that Go was encroaching on her land. A relocation survey was then conducted and it was found out that her total land area was decreased while the land of Yao increased.
Where a person had no knowledge that he encroached on his neighbor’s lot, he is deemed a builder in good faith until the time the latter is informed of his encroachment upon the latter’s property.
