Weekly conversation led by Dr Joelle Grogan to give you an in-depth understanding of the law stories making news and the legal decisions that could have a bearing on everyone in the UK.

This week:

Prenuptial contracts: what is a "prenup," as they're often called? Should you get one even if you're not wealthy? Are they legally binding in the case of divorce, or not worth the paper they're written on? What do you need to do for the courts to uphold them in the various parts of the UK? Family law solicitor and social media's "legal queen" Tracey Moloney has the answers.

And: Japanese knotweed, a fast-growing invasive species so tough it can only be successfully removed by professionals. A Scottish couple has been granted permission by an Edinburgh sheriff to sue the previous owners of their home, who had not declared that there is Japanese knotweed on the property. This case centres around whether or not it counts as an "infestation". Other home seller packs ask about knotweed explicitly. Dr Sam Fowles explains the law, and who you can sue if you find yourself with unwanted knotweed after all.
