Declaration of intent for divorce

Hello Rabbi Michi,

It’s T., hope you are well.

I have a question,
A few weeks ago, a column was published in Makor Rishon’s “Shabbat” written by someone from “Kolac” named Nitzan Caspi Shiloni.

There she talked about their new project, called a “security bill,” in which a man signs that he wants to give his wife a divorce if he is in a situation where he is not willing to give it (for example, a plant). In the article, the author claims that from a halachic perspective, it is easier to give a wife a divorce if it is known that the husband wanted it, and of course, a bill that he signed constitutes a fairly clear statement of intent. (She also wrote there that in the case of the “Get Safed,” the opponents claimed that it would have been much easier to grant that Get Zichuk if it had been proven that the husband had actually wanted it.)

My question is; what is the true halakhic validity of the man’s declaration of opinion, is it really likely to help in a case of need, and how worthwhile is it to approach signing such a document?

Thank you in advance and have a good weekend.

Talia
