A law firm in London has created a 'clean-up' prenup to help couples navigate the division of housework.
New research has found household chores cause arguments among 39% of co-habiting couples.
Legal firm Lawrence Stephens is working with cleaning product company Method, to highlight the gender 'spray gap'.
54% of women are still doing the majority of the housework.
Meanwhile, 59% of people surveyed said rows about cleaning up have led or have the potential to lead to the breakdown of their relationship.
But Clinical Psychotherapist, Stephanie Regan, says arguments about housework can reveal deeper issues:
"It's often within it, wrapped within it, is are you being fair to me?"
She says people tend to think, "Is there equality here? Are you doing as much as me? Is this fair?"
Common Rows
The research also found half of those polled expected praise or thanks from their partner when they finally managed to complete a task.
Leaving lights on around the house, not putting down the toilet seat, and not putting dishes away are among the most common reasons for arguments.
