HAP, or HAPP, in law, signifies to catch or snatch a thing. Thus we meet with, to hap the possession of a deed-poll. Littleton, fol. 8. also, to hap the rent. If partition be made between two parceners, and more land be allowed the one than the other, she that hath most of the land charges it to the other, and happeth the rent whereon assize is brought.
