What must be proven for the relation back doctrine to apply?

For the relation back doctrine to apply, it is essential to demonstrate that all delivery conditions were met. This doctrine is crucial in real estate transactions, particularly regarding transfers of property. The concept of "relation back" refers to the legal principle that an act may be treated as having taken effect at an earlier time than when it was completed, provided that certain conditions are satisfied.

In practical terms, the relation back doctrine often comes into play during situations involving the transfer of interest in property and can be critical in determining the rights and obligations of the parties involved. By proving that all delivery conditions were met, it can be established that the transfer was valid and effective as of the earlier date, which provides clarity regarding priority among claims or interests in the property.

The other choices relate to aspects of property transactions but do not directly pertain to the application of the relation back doctrine. Immediate transfer of title, notarization, and intended gifts are specific elements that may be relevant in other contexts but do not address the fundamental requirement for establishing that the delivery conditions necessary for the relation back doctrine have been fulfilled.
