Is it acceptable to follow the cultural practice of mahr now and delayed, but delayed only meant to be paid in an event of divorce.

Yes, it is. It is completely acceptable.

My recommendation, however, is for that to be clearly written in the contract.

Because there are some people who think muakhar is only for divorce, when in reality muakhar simply means to be paid later. And that's why they'll disenfranchise some women from their muakhar at the time of death.

They say, no, no, no, muakhar is not for later, muakhar is just for divorce. So, if you're going to be doing muakhar, meaning deferred or delayed amount to be paid and you know, some families essentially use it as a punitive measure to say.

Hey, you want to divorce my daughter? You're going to think twice about it.

She's going to marry you for $5,000 now. And for $50,000 due at divorce, then the man's going to think to himself, do I really want to put myself through that.

Now there might be positives and negatives to that, but it is something that contractually is permissible.

So yes, it is permissible for you to do that, but please state it clearly so that no one could come and say later that this was meant to be paid or it was not meant to be.
