Quick Answer

A non-Muslim couple's marriage is considered valid in Islam if: (1) they undertook a formal marriage ceremony recognized by their own culture and civilization, and (2) the parties are lawfully permitted to marry each other (i.e., not within prohibited degrees of relation). All four major madhabs agree on this. Mere cohabitation or common-law living arrangements are not considered a marriage. If the couple meets these two conditions and then converts to Islam, they do not need to redo their nikah. Ibn Abidin's position: the nikah of non-believers is valid when conducted in accordance with their own cultural norms.

The Question: What Constitutes a Valid Non-Muslim Marriage? — 19:39

A questioner asks: if a non-Muslim married couple converts, what is the minimum for non-Muslims to be considered married? When different non-Muslim societies conceptualize marriage differently — how do we know a couple from any given culture has a marriage instead of a mere living partnership?

Ibn Abidin's Ruling — 20:12

Ibn Abidin, the famous Hanafi scholar, states in his Hanafi textbook — and Yasir Qadhi cites this because it is the madhab he has studied most — that the nikah of the kuffar will be considered valid if it was done in accordance with their cultures and civilizations.

Every single civilization — without exception — has a ceremony that is deemed to be a public marriage. There is no civilization that lacks this. So what our fuqaha say is that if they have undertaken that ceremony, whatever it might be — whether by their priest or priestess, whether in their court, whatever it might be — there is something that happens that society recognizes as a formal marriage between a man and a woman.

Two Conditions — 20:55

There are two conditions for the marriage to be recognized:

First: they have undertaken the formal marriage ceremony according to their culture.

Second: the two people must be halal to be married in Islamic law. In some civilizations, they had incestuous marriages. Most famously — believe it or not — in the Zoroastrian civilization of pre-Islamic Iran, there were incestuous marriages among the nobility. If such a couple were to come before our courts, we cannot consider that a valid marriage. You cannot marry within the prohibited family degrees under any circumstances.

But other than that — if they have undertaken any type of vow or public contract that is recognized by their society — that is considered a valid marriage.

Cohabitation Is Not a Marriage — 21:42

Cohabitation — simply living together — is never deemed to be a marriage in any civilization. You might get some legal perks and protections in America: a common-law wife might get some money in a legal dispute. But a common-law wife is not deemed to be a legally wedded wife, even in American society. So in any civilization, if they have undertaken the appropriate ceremony — if they have done the vows, if they have done whatever needs to be done according to their culture — the Sharia considers that to be a valid marriage.

The Ruling on Converting — 22:08

If they are living in a non-Muslim state and they convert, they are deemed to be husband and wife. They do not need to redo their nikah. This is the position of all four madhabs.
