Final answer:
Voluntary alienation of title refers to the willing transfer of property ownership, which can occur through private grant or public grant, with private deeds and government land grants as examples.
Step-by-step explanation:
The two methods of voluntary alienation of title are through private grant and public grant. Voluntary alienation is the legal term for the willing transfer of the ownership of property from one individual to another. Private grant occurs when the owner voluntarily transfers the property to another private party, typically through a written document such as a deed. This method is the most common way property is conveyed in real estate transactions. On the other hand, a public grant involves the transfer of property by the government, such as through deeds for homesteads or land granted to railroad companies for developing infrastructure.
