You have written very well but the point I'm that draws my attention was this below:

Shielding youngsters from preceding relationships: A prenup can define monetary provisions for children from preceding marriages or relationships, making sure of their well-being and inheritance rights.

For peace to rain, the both party should have a separate bank account and one joint bank accout.

The reason is, if you as a wife want to send money to your sister that your husband don't really cherished, you can just do it from your account without telling your husband, likewise the man.

The joint account should be for the family upkeep. I think this will really safe conflict in the home.

Please do well to drop your comment on my post. Thanks for sharing and all the best.
