§ 720.650.When Third Person's Undertaking Becomes Effective

This short section ties the third person's undertaking to a concrete event: release of the property. Posting the undertaking and having it accepted doesn't, by itself, make the undertaking binding — the undertaking becomes effective only once the levying officer releases the described property back out of levy under this chapter.

That sequencing matters because it fixes the moment the third person's surety exposure begins. Before release, the undertaking is just a filed document; after release, it's the security the judgment creditor can pursue if the third person's claim to the property turns out to be wrong. § 720.660 supplies the other half of the picture — the levying officer's duty to carry out that release once the objection period runs.
