More interesting cases - to illustrate the halakhah. How far do they go toward kiddushin? (Spoiler: Not kiddushin). Plus, kiddushin with a shtar/document. Note - it's not worth even a perutah, nor is it a bill of sale, in that it comes from the woman's husband-to-be, and not her father (or herself, once she's an adult). Note the requirement for consent. Also, does the document need to be written for this woman specifically, like divorce, or not so, like betrothal via money?
