If two people become joint tenants on a house deed that they inheirit can one borrow against the deed without the other's consent?
Zero. Term insurance has no cash value from which to borrow. Although term policies do not have cash value, some do offer a rider called the ROP Rider (return of Premium rider). We have known of one company that allowed individuals to borrow against the value of their ROP rider. please contact your agent or the insurance company.
Can a lien be placed against a property which is in tenancy of the entirety but the judgment is against the husband only?
No. In most states that allow property ownership as "tenants in their entirety", a lien can only be placed against a property if all owners of record are included in the judgment. However, laws vary and most creditors will record the lien "just in case" the tenancy changes. The tenancy by the entirety could be broken by a death or divorce or if one partner conveys their interest to the other.
