Foreclosing on a Note With Partial Investor

[Franklin Tirrell]

Say that I buy a 30 year note and sell the first 10 years worth of payments as a partial to an investor. The borrower stops paying and I want to start the foreclosure process. Since the investor has partial ownership of this note do I need permission from him/her to foreclose? What if they own majority of the note (i.e. 20 out of the 30 years)? Does he have more say than me on foreclosing?
