Your husband is clearly a Mummy's boy & needs taking in hand, if he's not prepared to get off his fat *rse & do something in the house it's not fair of him to ask/allow his mother to come round & do the cleaning and he has no right saying anything to you about it either. I'd really hate to have someone come round & go through my stuff and rearrange everything - this is the opportunity to get your husband to do something, tell him you appreciate his mother's efforts but you don't want someone else interfering in your home, you aren't children, if he wants his mother to continue to act as chief cook, bottle washer & skivvy, perhaps he should go home to her then get to re-arrange everything to your satisfaction.
I think you also need to have a word with your mother in law, express your thanks for what's she's done but it is your household & you will run it as you see fit.
