Compulsory Conditions for Nikkah

[anonymous]

Assalamwalaikum

Are there a specific set of conditions both (compulsory / non compulsory) that need to be followed in order to make a Nikkah valid in terms of Sunnah and Quran, if so how does it vary between the 4 main schools of thought.

Hanafi
Maliki
Hanbali
Salafi

Questions are

Bride side:
if a parent or guardian / mahram exists, do they have to be there?
Can someone else be there in their stead?, i.e. bride father left this world, bride has one brother that does not agree to marriage, can brides brother in law be there in stead?

Groom Side:
if a parent or guardian exists (despite not having good relations with him), do they have to be there?

For initial viewings, bride wants to meet the groom for a look see and light conversation,
does the bride's brother or father or male / mahram have to be there (given that they do exist), what if they dont agree to the marriage and dont want to be there, what options does the bride have apart from making supplication

is it right to invite the groom over by himself so a family can present the bride? or should they demand that the groom brings a family member, more importantly a guardian right from the beginning of the whole process? male figures should protect the dignity and honour of their female family members right? if there is a meet, then they have a right that the guy should bring with him someone who is responsible for him, even though the guy is 33?

in our asian culture, despite family members not agreeing to marriages, is the mere attendance of mahram (although they are very reluctant to do so) enough to imply they agreed to the wedding.

in simple english it is wrong, bringing people in for the sake of it whilst their hearts say otherwise is categorically wrong...

despite saying Allah swt knows whats in everyones hearts, any deception to the community will be paid for at some point, what does our religion say?

Any advice according to our sunnah and the quran appreciated, Thanks....

going off point, sikh and hindu weddings have a reputation for wedding boycotts, people arriving on the wedding day protesting that they disagree and cause disruption... just a little info, it is true. lucky we dont have that

Correction : Any deception within the family or the community to justify a wedding/marriage will come back to bite the very people carrying out the deception... what does our religion say?

If your wali is being unreasonable, take the issue to whoever is the Islamic judge in your area, such as an imam or sheikh. If your wali continues to be unreasonable, let the islamic judge become the wali.
