What are the conditions for a valid nikah?
What are the conditions for a valid nikah? The core requirements in a row: consent, wali, witnesses, mahr, and the absence of impediments.

A nikah isn't just a ceremony; it's a contract with a number of conditions that determine whether it's valid. If you know what they are, you can take the right steps with peace of mind and avoid uncertainty arising later. On this page we go through the conditions for a valid nikah one by one, as a clear checklist. It's an explanation of the general requirements; on some details the schools of law differ, so for your situation an imam or scholar is the right person to ask. If you first want to know what a nikah is at its core, read what a nikah is.
1. Mutual consent
The first and most fundamental condition is that both partners consent to the marriage of their own free will. Islam has no forced marriages. A marriage that comes about under coercion isn't as it should be; the consent of both the bride and the groom is essential.
This isn't a formality, but the heart of the union. Without the sincere, voluntary consent of both, the rest stands on shaky ground.
2. Offer and acceptance (ijab and qubool)
A nikah is concluded with a clear offer (ijab) and a clear acceptance (qubool), usually in one sitting. One party (or the wali on behalf of the woman) makes the offer, the other accepts it, in unambiguous terms.
This exchange of consent is the moment the contract comes into being. It makes clear that both parties consciously and explicitly say yes to the marriage.
3. The wali (marriage guardian)
For the woman, the wali plays a part: her marriage guardian, usually the father, who consents on her behalf and oversees the conclusion of the contract. For the majority of the schools of law, the wali is a condition for a valid nikah, on the basis of the narration that there is no marriage without a wali.
Here the schools of law do differ: according to the Hanafi school, an adult woman can under conditions conclude her own marriage. What applies in your case depends on the school of law you follow. Read more about this role and the differences in what a wali is and why the role matters.
4. Two witnesses
A valid nikah requires the presence of witnesses, usually two upright Muslim witnesses. Their presence has a clear purpose: it makes the marriage known and prevents a secret union. Islam holds that a marriage shouldn't take place in secret.
The precise requirements for the witnesses, and why they matter so much, you can read in the role of witnesses at a nikah.
5. The mahr (dower)
The man gives the woman a mahr, a dower that becomes her property. The amount or form is determined by mutual agreement and ideally recorded clearly beforehand; "we'll arrange it later" doesn't do the mahr justice.
There's a nuance about the mahr: most scholars see it as an obligation of the man, but there's a difference of opinion about whether it's strictly a validity condition. Either way, it belongs to a correct nikah. Read more about what the mahr is and how it works in what is the mahr.
6. No marriage impediments
Finally, there may be no impediments that forbid the marriage. Think of too close a blood or in-law relationship, or a woman still in her waiting period (idda) after a previous divorce or bereavement. Suitability for marriage must also be met, such as a minimum marriageable age and the capacity to enter into the union.
If there are such impediments, the marriage can't be validly concluded. This is exactly the kind of situation where it's wise to put it to an imam or scholar, so you're sure nothing stands in the way.
And the Dutch context?
Important to know: these are the religious conditions for a valid nikah. They stand apart from Dutch law. A nikah isn't legally binding on its own in the Netherlands, and the law prescribes that the civil marriage comes before the religious ceremony. What that means for your rights and why you're best off arranging both, you can read in is an Islamic marriage legally valid in the Netherlands.
