Sale deed of a property executed by a non employee

Hello,

I wanted to understand the legal course for a case where the sale deed needs to be executed by a non employee. The property is owned by a pvt ltd company, and the directors won't be able to come down for property registration due to covid since they are in a different city. They are proposing to provide a Board resolution authorizing an unrelated, non employee to execute the sale on behalf of the company. What's the legal solution?

Thanks a lot.
