BACHLS, LP ceased to exist in July 2011, yet it is still maintaining legal actions across the country.   

Check your own state statutes. Under Oklahoma Code Title 54. Partnership 54-311.1 (F):

F.  A domestic limited partnership that has ceased to be in good standing or a foreign limited partnership that has ceased to be registered in this state may not maintain any action, suit or proceeding in any court of this state until the domestic limited partnership has been reinstated as a domestic limited partnership in good standing or the foreign limited partnership has been reinstated as a foreign limited partnership duly registered in this state.  An action, suit or proceeding may not be maintained in any court of this state by any successor or assignee of the domestic limited partnership or foreign limited partnership on any right, claim or demand arising out of the transaction of business by the domestic limited partnership after it has ceased to be in good standing or a foreign limited partnership that has ceased to be registered in this state until the domestic limited partnership or foreign limited partnership, or any person that has acquired all or substantially all of its assets, has caused the limited partnership to be reinstated as a domestic limited partnership in good standing or as a foreign limited partnership duly registered in this state, as applicable.  

Manufacturing performing loans into default because it still works...

Since the early 1990s, banks have used this same scam (described below) to steal homes. The paying customer sends in a full and timely payment, but the bank refuses to cash it, and then claim the loan is in default. This is called a manufactured default. The bank then piles on bogus fees and eventually initiates an illegal foreclosure action based on their own manufactured default; running into court with false statements claiming the borrower is not paying. This simple scheme has been used successfully for more than 20 years because it still works, and incredibly, judges are still falling for it. 

In most if not all states, this act of "making false statements to obtain property" is a state jail felony, and in Texas, it is punishable by up to 99 years in prison. 

What most homeowners don't know is the Uniform Commercial Code provides a remedy for this ruse:

§ 3-603. TENDER OF PAYMENT.

(a) If tender of payment of an obligation to pay an instrument is made to a person entitled to enforce the instrument, the effect of tender is governed by principles of law applicable to tender of payment under a simple contract.

(b) If tender of payment of an obligation to pay an instrument is made to a person entitled to enforce the instrument and the tender is refused, there is discharge, to the extent of the amount of the tender, of the obligation of an indorser or accommodation party having a right of recourse with respect to the obligation to which the tender relates.

(c) If tender of payment of an amount due on an instrument is made to a person entitled to enforce the instrument, the obligation of the obligor to pay interest after the due date on the amount tendered is discharged. If presentment is required with respect to an instrument and the obligor is able and ready to pay on the due date at every place of payment stated in the instrument, the obligor is deemed to have made tender of payment on the due date to the person entitled to enforce the instrument.
