Leading divorce lawyer Deborah Chambers QC says prenups shouldn't be a thorny issue between couples.

"Ideally it should be pretty matter of fact. We need to talk about this. And I know you're not in love with me for my money," was Ms Chambers advice on bringing up the issue.

When it comes to Prince Harry and Meghan Markle, she has $7 million, while he has $65 million.

This disparity firmly puts the couple in prenup territory according to Ms Chambers.

"They're certainly for people where at the beginning of the relationships, one party's got significantly more wealth than the other," she said.

Here's hoping the wedding of the year isn't a case of easy come easy go.
