§55-4-12. Payment or performance by mortgagor as defense.
The payment of the whole sum, or the performance of the whole duty, or the accomplishment of the whole purpose, which any mortgage or trust deed may have been made to secure or effect, shall prevent the grantee or his heirs from recovering at law, by virtue of such mortgage or trust deed, property thereby conveyed, whenever the defendant would in equity be entitled to a decree revesting the legal title in him without condition.
