Let's start with a definition:
"A legal representative is a person legally appointed to represent and defend the interests of a business."
In other words, this person is someone who can be a signatory for your company. It's oftentimes a business's general manager or, in the case of many independent, single-employee businesses, that person is you.
We ask you to provide this information because it's required for issuing invoices on your business's behalf. It won't appear anywhere else publicly on Malt, including on your profile page.
Important: If you benefit from wage portage, this person will be the legal representative of the wage portage company you work with, but on Malt you will have to indicate your own personal information and your identity proof.
