The instruments required to be recorded to show title based on a mortgage foreclosure by action are the sheriff's certificate of sale, and the sheriff's deed.
If mortgagor redeems, recording the original certificate of redemption will eliminate the foreclosed mortgage and does not affect status of junior liens. Satisfaction of the original mortgage is neither necessary nor desirable. Foreclosure cuts out subsequent liens and satisfaction or release of them is not necessary.
Satisfaction of lien holders, properly joined in the action, is not necessary.
