Is the digital signature in the daily report of the TIME App legally secure?

The construction diary (or the daily report) is not one of the contracts for which a law (e.g. the BGB) requires the written form. The electronic form is therefore basically possible here.

In order to ensure recognition by your client, it is advisable to have the basic collection of digital signatures in a contract recognized by both sides.

We recommend that you discuss the procedure individually with your legal adviser and / or your professional association.
