Girls please advise!!

So my mom owes me and my husband a significant amount of money she has some saved but that's for a house she's going to close and she can't move the money from her account until the bank is done processing. All her info. And we are in need of a new car asap bc our vehicle is not working anymore she said she gets paid in 2 days. My husband is pressuring me to get the money from her NOW I'm in the middle and idk what to do :(
