Bigamy is a ground for annulment

Imagine finding out that your spouse was already legally married to someone else before marrying you.

This situation -known as bigamy- has serious legal consequences.

Bigamy is a criminal case in the Philippines used to criminally charge one of the spouses if he or she married someone without first ending a previous married (Article 35(4) of the Family Code.)

Bigamy is a ground for annulment so you can file an Annulment to end your marriage.

However, can you file for annulment or is another legal process required?

Annulment is a family law case used to end the marriage.

Where as bigamy is a criminal charge.

These are 2 separate cases.

In this article, we will answer common questions, such as the difference between annulment and bigamy in the Philippines, the evidence needed, and the process for filing an annulment in such circumstances.

Can I file an annulment if my spouse was married before and not legally separated?

A marriage that is void from the beginning still requires an annulment

Yes, you can file for annulment in the Philippines if your spouse was previously married and not legally separated when you married.

A marriage like this is void from the beginning.

This is because Philippine law only allows someone to be married to one person at a time.

So, any marriage that happens when one of the parties is already married is void from the beginning.

However, you will still have to go through a court case called Annulment (or more technically Nullity of Marriage) if you want to legally end the marriage and remove this marriage from your PSA record.

Please note also –

Annulment and bigamy in Philippine law is different cases.

These are separate cases with very different effects.

In the Philippines, bigamy is a criminal case which can put someone in jail while annulment just ends the marriage.

(I understand some people will be upset and want to file bigamy cases, but it just costs a lot of time and money. Getting an annulment may help in just allowing you to move on with your life.)

What is the difference between annulment vs bigamy?

Annulment is a civil case while bigamy is a criminal case

In the Philippines, marrying someone who is already legally married carries serious legal consequences — both civil and criminal.

The difference between Annulment vs Bigamy in the Philippines is that the first type of case ends a marriage while the second type of case criminalizes the act of marrying while already married.

Let’s discuss annulment first.

Annulment is a court case that ends a marriage, dissolves conjugal property and removes a spouse as a compulsory heir.

Basically, annulment process declares a marriage null and void, as if it never legally existed from the beginning.

There are two Types of Marriage Nullification in the Philippines:

First, Annulment (Voidable Marriage).

Which the marriage is valid until annulled by a court.

It applies when there were issues at the time of the marriage, but it was not automatically void.

And, Declaration of Nullity (Void Marriage)

Which the marriage is invalid from the beginning.

Although annulment and nullity of marriage often confused, both served same purposes which is to declare a marriage legally invalid, granted freedom to remarry, and protected both legal rights.

On the other hand,

Bigamous marriage is considered void ab initio (invalid from the beginning) under article 35 of the Family Code.

Meaning, no legal rights arise from it. No conjugal property, spousal support, inheritance rights and child legitimacy.

Bigamy is a criminal case in Philippines that is filed when one spouse marries while still married to their first spouse.

Under Philippine law, bigamy is defined any person who shall contract a second or subsequent marriage before the former marriage has been legally dissolved, or before the absent spouse has been declared presumptively dead by means of a judgment rendered in the proper proceedings.” Article 349 of the Revised Penal Code

Bigamy happens when a person marries someone else while still legally married to another, and the first marriage has not been annulled, dissolved, or legally ended.

To be liable for bigamy, the following must be present:

  • There is a first valid marriage.
  • The first marriage is still in effect (not annulled or legally ended).
  • The person contracts a second marriage.
  • There is no court declaration of presumptive death (in case the first spouse is missing).

Bigamy is punishable by prisión mayor, which means 6 years and 1 day to 12 years

Bigamy can end up with the perpetrator being in jail (although that is not always the case, for example, prescription may apply.)

Bigamy may be filed by the public prosecutor attached to a court.

You can do each in separate cases but the cost of filing three cases is quite high and so annulment is the best and cheapest way to do.

For example is the case of Luisito Pulido who got convicted of bigamy and his marriage declared null and void:

Case Study: Luisito Pulido — Nullity of Marriage Confirmed After Bigamy Conviction

In G.R. No. 220149, Luisito Pulido was convicted of bigamy after marrying Rowena Baleda in 1995 while still legally married to Nora Arcon, whom he wed in 1983. Pulido argued that both marriages were void — the first allegedly lacked a valid marriage license, and the second lacked a proper ceremony. However, the courts found that his first marriage was presumed valid, and that he had not obtained a judicial declaration of nullity before entering the second.

Despite Pulido’s defense, the Regional Trial Court, Court of Appeals, and ultimately the Supreme Court upheld his conviction. The second marriage was later declared void for being bigamous, but the criminal liability remained because the first marriage was still subsisting at the time of the second.

In 2015, the RTC of Imus, Cavite issued a final judgment declaring Pulido’s first marriage void, followed by a Decree of Absolute Nullity in 2016. However, this did not absolve him of bigamy, as the second marriage was contracted before the judicial declaration of nullity.

They are filed in the Family Court and require evidence such as your marriage certificate and a certified copy of your spouse’s prior marriage certificate to prove that the first marriage was still valid at the time of your wedding.

Annulment cases are filed both online through a personal visit to the court.

Annulment on the grounds of bigamy is filed at the RTC Family Court.

As part of the bigamy annulment process, the petition should be filed in the court that has jurisdiction over where you or your spouse currently resides.

So, if you live in Tagaytay, your lawyer will file the petition for annulment in the Tagaytay RTC. Alternatively, if your spouse resides in Makati, the bigamy annulment process can also be initiated there.

Choosing the correct venue is an essential part of the procedure to ensure the case moves forward efficiently and within the bounds of the law.

What are the evidence needed for Annulment when one spouse was still married when you married?

Pile of documents

If one is already married, what you will get is Advisory on Marriage

Although witness testimony, emails and text messages can be admitted, it is important to get actual documentary proof, evidence needed that is grounds for annulment (that one of the spouses was married at the time you married).

Some of these documents are the following:

  • CENOMAR (Certificate of No Marriage): The Philippine Statistics Authority (PSA) releases this certificate when a person has no record of a marriage.

If the person has a record of marriage, then the PSA will instead release an Advisory on marriage where his or her marriages will be listed.

  • PSA Marriage certificates will also be needed.

Other official documents demonstrating the existence of the prior marriage can be included.

  • Emails, texts and photos

Photos of the first and second marriages with system generated timestamps can be helpful.

Texts or emails showing evidence that the 2 marriages existed at the same time can also be admitted.

  • Witness testimonies

Testimonies from individuals who can attest to the existence of the prior marriage and the knowledge of both marriages can be valuable evidence.

These witnesses will likely be called to court, so please make sure that they can actually attend a court hearing.

 

What if your spouse used another name to get married?

Falsifying public documents is a serious crime

If your spouse used a different name to marry without legally separating first, you’ll need to find proof that they are the same person.

  • Documents showing both names such as government-issued IDs, driver’s licenses, or employment records.
  • DNA samples of children from both marriages showing that the same person was the father or mother.
  • Testimony from people who can confirm that the person with the different name is the same person in both marriages.

Other documents that may exist that prove that the same person was involved in both marriages.

What if your spouse used a fake marriage license so that he could marry without legally separating first?

A fake marriage license

A fixer is someone who has access and contacts “inside” a government office

If a fake marriage license was used for the second marriage, you will need to present proof that the marriage license had a grave error.

You will need to get the marriage license application from the Local Civil Registry for both marriages.

You will physically need to go to each Local Civil Registry. Ask for the entire file and if they cannot present one, ask for a Certificate from them acknowledging this fact.

If the fake marriage license was procured through a fixer, consult first with a Philippine family lawyer so that he can help you determine the proof you need.

Can I file Annulment based on Bigamy from abroad?

Additional processes like apostillization of petitions and other documents may add to the scope of work and the cost

Yes, you can file for annulment in the Philippines on the grounds of bigamous marriage even from abroad, but you might have to come for testimony.

There are video conferencing options available.

However, these options rely on the following:

  • If the judge allows
  • If there is a consulate near where you live that offers videoconferencing testimony.

In some cases, the judge absolutely insists to have an in-person testimony.

In those cases, you must appear or risk the case being dismissed.

A good lawyer will always tell you that is a possibility although they will also try to ask the judge for the opportunity to do a videoconference testimony instead.

Does the annulment deal with property and child support issues?

Child support can also be discussed in the case but it not advisable as it may prolong the case

An annulment ends issues with regard to property rights for properties that you will buy in the future.

An annulment can also end issues with regard to current properties that you own jointly and the case can also tackle child support issues.

However, adding property issues and child support issues when the spouses disagree may lead to a very long, very expensive annulment case that may fail.

If there is disagreement on these issues, consider separating them from the annulment based on bigamy case so that the annulment at least can succeed.

Talk it over with your Philippine family lawyer.

He’ll best be able to advise you on the best thing to do.

It may sometimes be that you will have to file separate cases for child support or property.
