Short answer. Yes. Failure to comply with a required condition precedent, such as barangay conciliation before filing, is one of the specific affirmative defenses the Rules of Court let a defendant raise in the answer — but it must be raised there, at the earliest opportunity, or it is treated as waived.

Condition precedent is a listed affirmative defense
Rule 8, Section 12 lists a specific, limited set of grounds a defendant may raise as an affirmative defense in the answer, and one of them is squarely on point: that a condition precedent for filing the claim has not been complied with. Barangay conciliation is a common example of a condition precedent in disputes between residents of the same city or municipality — if the case should have gone through that process first and did not, the missing step can be raised as this specific affirmative defense rather than argued informally or ignored.
Why the defense has to be in the answer itself
The rule is specific about where and when this defense must appear: a defendant shall raise his or her affirmative defenses in his or her answer, and the grounds are limited to those the rule enumerates, including lack of jurisdiction over the defendant, improper venue, lack of legal capacity to sue, failure to state a cause of action, and the unmet condition precedent. Raising the missing step later, or only mentioning it in passing during hearings, is not the same as pleading it as an affirmative defense in the answer where the rule requires it.
The cost of not raising it early
The rule also carries a real consequence for delay: failure to raise the affirmative defenses at the earliest opportunity constitutes a waiver of them. That means a defendant who has a genuine condition-precedent defense but does not raise it in the answer generally loses the ability to raise it later, even if the underlying procedural step really was skipped. This makes it important to identify the missing step and plead it clearly and promptly, rather than treating it as something that can be brought up whenever it becomes convenient.
What happens after the defense is raised
Once pleaded, the court is required to resolve the affirmative defense on its own initiative, within thirty calendar days from the filing of the answer. If the defense is denied, the rule does not allow it to be challenged right away through a motion for reconsideration or a special civil action — instead, it becomes one of the matters that can be raised on appeal once the case reaches a judgment on the merits. So raising the defense early protects your position for later, even if the trial court does not immediately agree with you.
