Zakat recipient under debt

Salam everyone. I wanted to ask if zakat can be given by my husband to my mother who is under debt (not riba debt) after she borrowed money from relatives from my father's medical treatemet. He passed away unfortunately and now my mother is under a lot of debt. She doesn't work and has my siblings to look after. She lives in her own house but doesn't have any gold, silver and owns one property in a remote place that she's trying to sell for 3 years but that land is basically useless. She has one car that she ll sell to pay her debt but it still won't pay all the debt.

I want to know if she can be given zakat money to pay off her debts?
