§ 293. Recording of conveyances heretofore acknowledged or proved. A
conveyance of real property, within the state, heretofore executed, and
heretofore acknowledged or proved, and certified, so as to be entitled
to be read in evidence, or recorded, under the laws in force at the time
when so acknowledged or proved, but which has not been recorded is
entitled to be read in evidence, and recorded in the same manner, and
with the like effect, as if this chapter had not been passed. If
heretofore executed, but not proved or acknowledged, it may be proved or
acknowledged in the same manner as conveyances hereafter executed and
with like effect.
