Which document is NOT a method for obtaining proof of title?

A deed of assignment is not typically regarded as a method for obtaining proof of title. It is a legal document that conveys the rights associated with a property, often from one party to another, but it does not itself establish ownership or title to the property. Proof of title generally requires documents that demonstrate ownership, such as a grant of probate, which is necessary to transfer property after someone has died, or a land registry certificate, which officially records ownership. Additionally, letters of administration serve a similar purpose as probate but apply when a person dies without a will, allowing someone to manage the deceased's estate. Each of these documents provides evidence of ownership or a claim to the title, which is why they are considered valid methods for proof. In contrast, a deed of assignment does not serve this function.
