Abandon

From Advocatespedia

v. to intentionally and permanently give up, surrender, leave, desert or relinquish all interest or ownership in property, a home or other premises, a right of way, and even a spouse, family, or children. The word is often used in situations to determine whether a tenant has left his/her apartment and the property inside and does not intend to come back. Thus, a landlord can take over an apparently abandoned residence, but must store anything a tenant leaves behind and give notice to the tenant before selling the possessions, which are left. To abandon children can mean to have no contact and give no support for a year or more.
