Short answer. Yes. Contracting a subsequent bigamous marriage is the seventh ground for legal separation, and the article says expressly that it counts whether the ceremony took place in the Philippines or abroad. A wedding overseas does not put it beyond the reach of the clause.

A ceremony, not just another relationship

The clause turns on Contracting by the respondent of a subsequent bigamous marriage. What it describes is a marriage entered into while yours still subsists — a second ceremony with the formalities of one, not a live-in relationship however long-standing or however openly conducted. A spouse who has a second household and children with someone else has certainly given you a ground, but it is the one about sexual infidelity rather than this one. The distinction matters because the two are proved in completely different ways.

Abroad is expressly covered

The phrase whether in the Philippines or abroad was put there for a reason. It closes off the argument that a marriage celebrated in another country, under another legal system, is somehow outside the reach of the provision. This is the common pattern in practice: a spouse working overseas marries there, sometimes in the belief that distance makes it a separate life. On the wording of the clause the location of the ceremony makes no difference at all.

The second marriage is itself in serious trouble

Two other consequences run alongside your family case, and it is worth knowing they exist. A marriage contracted while an earlier one subsists is void, so the later spouse has no standing as a spouse whatever they were told. Bigamy is also a criminal offence, which means a separate case with its own evidence and its own timeline. Those proceedings are independent of the legal separation and none of them is a substitute for the others.

The certificate is the case

This is one of the most document-driven grounds in the article. What proves it is the marriage certificate or its foreign equivalent, together with your own, and a certification of the civil registry records. Photographs and social media may tell you where to look but they do not establish a marriage. Obtaining a foreign record takes time and usually needs authentication, so start that early. Be candid with a lawyer about when you learned of it, since prescription and forgiveness after the fact are separate bars to relief.
