Possibilities for litaral enslavement
Definition of a slave

"One who is the property of, and entirely subject to another person, whether by capture, purchace or birth; a servant completely divested of freedom and personal rights"
Being a slave by birth, but living in a free society, slavery and total prefarable internal enslavement will always be in the first place a matter of free choice of the person.. Because a slavecontract is not enforced by law, just because it is not considered to be legal in contrary with a marriage contract
To overcome this problem of legalness  and to enforce a slave into  longlasting enslavement ,the total permission of the slave is needed to create a situation in which  the  furure Owner will be able to bring the potential slave in a position from which is no way out
Methods,
Knowing your future Owner, preferable having met him face to face,  when you are still free and not yet his property, before deciding  to become his property for real

After making arrangements and appointments  with your future Owner going voluntarily to him preferable abroad and leaving your old  life behind you, in this case you must be absolutely sure of your future Owner






methods: Capture, kidnapping, abduction; by taking the slave blindfolded to an unknown and isolated place,  where he will be imprisonent and isolated from the outside world. During this period of total imprisonment and isolation from the outside world,the  Owner will start to submit the slave to  severe and  training programs

Psychological Methods: Brainwashing, interrogation
