 If, however, the heir of any such be under age, his Lord shall not have wardship of him, nor of his land before he has received his homage, and after being a ward such an heir shall have his inheritance when he comes of age, that is, of twenty-one years, without paying relief and without making fine, so, however, that if he is made a knight while still under age, the land, nevertheless, shall remain in the wardship of his lords for the full term.
