Understanding Void and Voidable Marriages Under Philippine Law
If you've started researching how to legally end your marriage, you've probably noticed that people use the word "annulment" for almost everything — even when what they actually mean is a declaration of nullity of marriage. A friend may have told you to "just file for annulment," while someone else insisted you need "nullity" instead. This mix-up is extremely common, but the two are legally distinct processes, with different grounds, different deadlines, and different consequences.
This guide breaks down annulment vs declaration of nullity of marriage in the Philippines — what separates them, which one might apply to your situation, and why getting this distinction right matters before you file anything in court.
Void vs. Voidable: The Core Legal Difference
The entire distinction comes down to one legal concept: whether your marriage is void or voidable.
A voidable marriage is considered valid and produces full legal effects, until a court sets it aside through annulment. Until that happens, the marriage exists in the eyes of the law.
A void marriage is treated as if it never legally existed at all, from day one. A declaration of nullity doesn't end the marriage, it simply confirms, officially, that there was never a valid marriage to begin with.
This distinction affects everything else: the grounds you can raise, how long you have to file, and even how the case is argued in court.
What Is Annulment? (Voidable Marriages)
Annulment applies to marriages that were valid when celebrated but suffer from a specific legal defect present at the time of the wedding.
Legal basis: Article 45 of the Family Code lists the exclusive grounds for annulment: lack of parental consent (for a party aged 18 to below 21 at the time of marriage), unsound mind, fraud, force or intimidation, physical incapacity to consummate the marriage, and a serious, incurable sexually transmissible disease.
Because these marriages are only voidable, not void, they can even be ratified in some cases — for example, if the parties freely cohabited after the reason for the defect no longer applied. Until a court grants the annulment, the marriage remains legally binding.
What Is Declaration of Nullity? (Void Marriages)
A declaration of nullity applies to marriages that were legally defective from the outset — meaning the law never recognized them as valid marriages in the first place.
Legal basis: Article 35 of the Family Code voids marriages contracted without a valid marriage license, those celebrated by parties below 18, bigamous or polygamous marriages, and certain incestuous or public-policy-prohibited unions. Article 36 separately voids a marriage where a party was psychologically incapacitated to comply with essential marital obligations at the time of celebration.
Because the law treats these marriages as if they never happened, an action to declare a marriage void generally does not prescribe, there is no deadline by which you must file, unlike with annulment.
Annulment vs. Declaration of Nullity: Side-by-Side Comparison
Feature | Annulment (Voidable Marriage) | Declaration of Nullity (Void Marriage) |
Legal status of the marriage | Valid and binding until annulled | Treated as if it never legally existed |
Governing article | Article 45, Family Code | Articles 35 and 36, Family Code |
Example grounds | Lack of parental consent, fraud, force, impotence, serious STD | No marriage license, bigamy, underage marriage, psychological incapacity |
Deadline to file | Yes, specific prescriptive periods under Article 47 | Generally none, the action does not prescribe |
Can it be ratified? | Yes, in some circumstances | No |
Effect on children conceived before judgment | Remain legitimate | Remain legitimate under Article 54, for certain grounds including psychological incapacity |
How Long Do You Have to File an Annulment?
Unlike a declaration of nullity, annulment cases are time-sensitive. Missing the deadline can permanently bar your case, no matter how valid your grounds might otherwise be.
Legal basis: Under Article 47 of the Family Code, the prescriptive periods are: 5 years after turning 21 (lack of parental consent); anytime before the death of either party (unsound mind); 5 years from discovery (fraud); 5 years from when the force or intimidation ceased; and 5 years from the date of the marriage (impotence or serious STD).
If you're unsure whether your specific circumstances still fall within these windows, this is exactly the kind of question to raise with a lawyer early — prescription under Article 47 is treated as jurisdictional, meaning a late filing can bar the case entirely, regardless of merit.
What Happens to Your Children and Property?
Many people delay seeking legal help because they fear a void or annulled marriage will make their children "illegitimate" or leave them with nothing. In most cases, that fear is misplaced.
Legal basis: Article 54 of the Family Code provides that children conceived or born before the judgment of annulment, or before a judgment of nullity based on psychological incapacity under Article 36, are considered legitimate. Property acquired during the marriage is also generally subject to liquidation of the couple's property regime, whether annulled or declared void.
Because property and custody consequences shift depending on the ground and timeline involved, this is an area where case-by-case review matters more than general rules of thumb.
Common Mistakes to Avoid
Using "annulment" as a catch-all term. This causes confusion when explaining your situation to a lawyer — knowing which category you fall under saves time.
Missing the Article 47 filing deadline. Because annulment grounds prescribe, waiting too long can permanently close off an otherwise valid case.
Assuming a void marriage needs no court action. You generally still need a court judgment declaring it void before you can safely remarry or resolve property and custody matters.
Overlooking psychological incapacity as a nullity ground. Many default to thinking "our marriage just didn't work" only qualifies for annulment, when a deeper, enduring incapacity may fall under Article 36 instead.
Frequently Asked Questions
Can I just choose whichever process is faster?
No — the process depends on which specific ground applies to your marriage, not personal preference. A lawyer can help assess which category fits.
What if my grounds don't fit neatly into either category?
Some situations need careful legal analysis to determine the correct ground. It's best to have your specific facts reviewed rather than assume based on general descriptions online.
Do I need to go to court for a void marriage, or is it automatically void?
You typically still need a court judgment declaring it void — this is what allows you to remarry and legally settle property and custody matters.
Is there a deadline to file for declaration of nullity?
Generally, no — unlike annulment, actions to declare a marriage void do not prescribe. Related issues like property or support claims may still have their own timelines.
Summary: Annulment vs Declaration of Nullity of Marriage
The core difference in annulment vs declaration of nullity of marriage comes down to void vs. voidable — whether the marriage was ever legally valid at all.
Annulment applies to voidable marriages under Article 45 and has strict filing deadlines under Article 47.
Declaration of nullity applies to void marriages under Articles 35 and 36 and generally does not prescribe.
Children conceived before judgment are typically still considered legitimate, but property and custody outcomes depend on your specific facts.
