Frequently Asked Questions

Everything you need to know.

Are letters of intent binding when signed electronically?

LOI binding force depends on the document's language, not the signature method. Provisions explicitly stated as binding (confidentiality, exclusivity, break fees) are enforceable whether signed electronically or in ink. Electronic signing via Zignature provides strong audit evidence of execution.

What LOI provisions are typically binding vs non-binding?

Typically binding: confidentiality, exclusivity (no-shop), governing law, and break fees. Typically non-binding: purchase price, deal structure, and conditions to closing (these are negotiated in the definitive agreement).

Can both parties sign an LOI simultaneously using Zignature?

Yes. Configure parallel signing — both parties receive signing invitations simultaneously. This is common for LOIs where competitive speed matters.

How do I handle LOI negotiations before signing?

Use Zignature's document revision workflow to exchange redlined versions. When both parties agree on the final text, lock it for signing — no more version confusion.

Can I add an expiry date to the LOI signing request?

Yes. Set a signing expiry date on the LOI request. If the counterparty doesn't sign by the deadline, the request expires — preventing stale acceptance of terms that may have changed.

Should an LOI be executed before or after due diligence?

An LOI typically precedes due diligence — it establishes the indicative terms and grants exclusivity for the due diligence period. The definitive agreement is executed after due diligence is complete.
