Possessory liens and legal liens are two securities that has been the subject of debate from legal scholars for quite some time. Possessory liens are often viewed as a weaker security compared to legal liens. However, upon closer examination it turns out that possessory liens in most cases provide the the same opportunity to sell the property withheld as security. This possibility makes possessory liens resemble, if not be identical to, legal liens. Both securities arise by operation of law and grant the right to both withhold and sell property in the event of non-payment.
