how can put a voluntary lien on my house . I want to borrow some money from a friend but he wants to place a lien on my house for the amount borrowed?
Normally a party secures a loan of money by hypothecating real property, using either a mortgage or a deed of trust. The instrument most often used in California is the deed of trust. I would suggest that you get legal advice, before drafting and executing the instrument.
Mr. Roach is correct in his long winded answer. You use a document called a deed of trust. Most title companies can help you with the documentation for a modest fee.
