My husband's business partner wants to buy my husband's half of the business with a note. How can we guarantee payment of this note?

There is almost no way to guarantee payment, but a security interest in all of the business sold including the stock would provide better assurance of payment and a possible remedy and relief for  non-payment.This is not intended to be legal advice, and is general in nature.
