Short answer. Yes. Good faith is always presumed, and the burden of proving bad faith rests on whoever alleges it. So a possessor does not have to establish his own honesty; the party attacking him has to produce the evidence that he knew of the defect in his title.
What the law says

Where the burden sits, and why that decides cases
Article 527 is one sentence: good faith is always presumed, and upon him who alleges bad faith on the part of a possessor rests the burden of proof. Allocating the burden is not a technicality — it decides who loses when the evidence runs out. If nothing is shown either way about what the possessor knew, he is treated as having been in good faith, and the consequences that follow for fruits, improvements and deterioration follow with it. The party who wants the harsher treatment applied has to earn it.
What proving bad faith actually requires
Bad faith is awareness of the flaw, so it has to be shown by something that reached the possessor: an annotation on the title he examined, a demand letter received, a case already filed and known to him, a prior deed he signed, an admission in his own correspondence. Suspicion does not do it, and neither does the strength of your own claim — a true owner can be entirely right about ownership and still fail to prove the occupant knew anything. Bad faith is a fact about the other person's mind, established through documents, not an inference from the fact that he was wrong.
A presumption, not a shield
Two limits are worth keeping in view. The presumption can be overcome, and it is overcome routinely once a written demand or a registered notice enters the picture, because from then on the possessor cannot claim ignorance of what he has been shown. And it operates only where good faith is in issue at all — it does not make a defective title valid, does not defeat a registered owner, and does not convert a possessor into an owner. It affects how the consequences of possession are distributed, not who the property belongs to.
What to do with this practically
If you are the owner, the most useful thing you can do is destroy the presumption early: write to the occupant setting out your claim, attach the title, and keep proof of when it was delivered. Every day after that date is on a different footing from every day before it. If you are the possessor, keep the whole file from your acquisition — deed, title copy, receipts, correspondence — because although you do not carry the burden, the documents showing what you checked before you paid are what will answer the allegation when it comes.
