No, this does not happen in the west. In the UK, the brides family was once expected to pay for the wedding. This is tradition, but it is not a rule. If a rich man marries a girl from a poor family, it wouldn't be fair if the girls family had to pay for things.

I agree with Rich. This does not happen in the West and I think it would actually be considered quite inappropriate. I think it would also be considered rude if the bride's family were expecting to receive money. As Rich said, sometimes the bride's family (specifically, the bride's father) might pay for the wedding, or contribute largely to it, but I'd say this is an outdated tradition.

Agreed with Rich and Daniel. The word for this gift is "dowry", and it is traditionally provided by the bride's father, in the form of paying for the wedding. As far as I know, modern couples prefer to cover all basic expenses themselves, without help from relatives.

NEVER. Any man that gives money to a family in order to marry must be a complete idiot.

No this does not happen in Australia either. Both sets of in laws would meet and get to know each other before their children marry and would talk about who would pay for what at the engagement party and wedding. Most couples in Australia live together before they get married and often have a lot of household furniture and in some cases a house as well. If parents are rich they may give the young couple money to help them buy a house.
